The first working bench version of my button-controlled Meshtastic handheld is up and running on a Heltec Vision Master T190.
The buttons now navigate the menus, and I can compose and send messages from the device. The screen shows the node world, inbox, channel, and signal info. I’m going for a colourful, pixel-art, NES-inspired look.
It’s still a bench prototype. I’m fixing some font spacing, text collisions, and emoji rendering before moving on to the finished enclosure.

Hi there!

I want to get into Meshtastic. For a portable one, which one should I buy? Or if you have others ones to show me. I'm in Canada buy the way! Thanks!

Hello everyone.

Since I joined the meshtastic community with my new Xiao ESP32-C3, I decided to design an interesting case for this device to put on a windowsill.

I like the Meshtastic logo, so I used those shapes. It wasn't easy to fit it all into a small case. I spent some time r/3Dmodeling in r/blender.

The r/3Dprinting may not be perfect, but I might work on it.

The final colors were supposed to be the Meshtastic logo, but I don't currently have the filaments.

As you can see, there's a small OLED display on the front, a small ventilation window on the back, a button for changing pages in the menu on the top, and a USB-C port on the right.

I hope you like it. Best regards.

I picked up the v3 board and didn't find any cases which used 21700 batteries. I fixed that. Fully designed by me with no AI. Fits the board and 217002P battery pack. The pack is spot welded together with the power leads by I. Plenty of room for other battery options but they would be loose. Cut outs for the antenna, LED, and buttons. Tested with the included stubby and muzi works antenna. I'm working on a case for v4 now as I did not care for the v3 and grabbed some v4 boards which are working way better. Find the model free here: https://makerworld.com/en/models/3443167-heltec-v3-lora-case-using-21700-batteries#profileId-3926651 v4 case on the way.

I have a think node M6 mounted on my roof, and a T096 as my companion. When I look at the node list they both see 54 nodes, and usually anywhere between 6-9 online at a given time. If I send a test message on long fast I get a few responses, but if I try to direct message the same nodes it shows "relayed, not confirmed by recipient" and the user on the other end doesn't get my message.

I'm semi new to this so if someone could ELI5 that would be great

When i try to connect the L1 with my phone, it shows the needed code on the device for a split second until it disappears again and even if i try to memorize it and put it in correctly, nothing happens

Good Evening

I am brand new to the world of mechanistic and just put my first node together. I purchased a kit from Meshology, ESP32 LoRa V3. It came with a Heltec LoRa 32 and I have parts left over and want to make sure I’m not missing anything and find out what I have left over. Should any of this be installed?

I have it programmed and connected through the app but haven’t found any other devices but from what I understand you should be outside for that. Anything else not super technical I should getting started?

Rate my build

I'm planning to modify firmware because I want to add a button for GPS. However, I can't connect my faketec nrf52 in Arduino IDE, that's where I'm planning to create mine.

So I have these RAK Wizblocks from a Helium development kit im trying to use for Gps through Meshtastic. and right now, I'm at my wits end. I went to the web flasher, It would not go into DFU. I did it manually, downloaded the UF2, and the folder would not close and restart. I checked forms and it said it needed a new bootloader. I downloaded python and ran it through terminal, no location or smth. tried to do it through the Arduino Serial monitor, didnt show up. I could see it on device manager as COM11 called Feather nRF52840 Express. At this point it has given me 3 headaches lol. I have 3 of these chips and dont want them to go to waste so some help would be awesome or just send to a company that flashes these for a small charge.

Hello everyone

As a LoRa fan since around 2018 I decided to build my first solar node using wio tracker l1 lite (EU_868).

I've seen people building theirs and got some good ideas about what components to use.

My setup will be like this:

• A waterproof junction box
• An (most probably) alfa antenna on top with the proper connector and sealing
• An IP68 Vent in the bottom (I saw it somewhere)
• A 18650 battery holder and the battery itself

I am not familiar with solar power or power management in general and I need your help on choosing a solar panel. In seeedstudio's wiki for the l1 lite they say the following

Well, this "do not exceed 5v got me worried.

At first I was looking on aliexpress, banggood and temu for a panel with a mount that had JST 2.0 as output, then some 5V panels which had usb port with some pictures of charging a phone and I was thinking to connect my module through usb.

I've seen people using some 1W or 1.5W ones but I've read somewhere that they won't be enough for my setup.

Basically I don't want to complicate my setup by adding more components or 3d printing and of course I don't want to fry the board hahaha.

Thank you

Hi all! I'm part of Meshbrasil ( https://www.meshbrasil.com ), an unofficial Meshtastic community in Brazil (guides, regional groups, a marketplace and a setup wizard, mostly in Portuguese). We put together an interactive explainer of what happens when you hit send, and I'd love help making it better.

Try it: https://meshbrasil.com/como-a-mensagem-viaja.html (English and Portuguese)
Code: https://github.com/rogerio-richa/meshbrasil-anatomy (MIT)

It has three scenes:

1. Sending a message - type on a handheld. The readout shows your text size, the packet size and the LongFast time on air (SF11 / 250 kHz / CR 4/5, using the ANZ settings we use on this neck of the woods)

2. Riding the waves - the packet drawn as a waterfall in perspective: 16 preamble up-chirps, the 0x2B sync word, 2.25 down-chirps, then the data symbols. You can switch between clean lines and a heat map computed from the same chirps.

3. Mesh at work - a little suburb with nodes on the roofs. The message floods the way Meshtastic does it: weaker-signal nodes rebroadcast sooner, a node cancels if it hears someone else relay first, and each relay uses one of the 3 hops. There's even a CLIENT_MUTE node that listens but never forwards.

Everything is plain SVG + JavaScript, no framework and no network calls. The geometry is computed at build time and the browser only animates it.

Would love your help/contribution/suggestions on how to awesomize it. The simplifications are listed in the README. If something is wrong, tell me, that's the whole point!

Built with help from Claude 5.5 and the awesome Anatomy ( https://github.com/wheresryan22/anatomy ) drawing kit.

Hello all,

Just got started with Arduino and love what I'm learning so far. As someone interested in Mesh though, I was wondering if anyone here had built any projects with an Arduino board to use with metastatic.

Sorry if it's the wrong board just thought I'd start here.

Hello. Everyone, I hope y'all are doing well.

A while ago I bought the t1000e to join the network and learn a little about lora and mesh. I was able to chat on the default channel using mqtt since at the time there wasn't any local node around me. I finally got me another t1000e and the $10 node I can't recall what is called. Updated firmware to the latest and set them up. I can only see them only when I'm near by, once I am about 2 blocks away, I can't communicate with other 2 nodes despite the fact that those are connected to either a tablet or a laptop. Would that be a firmware issue?

What am I doing wrong?

Thanks for any input.

Edit: I forgot to add, all 3 devices are connected to the mqtt server. I will get msgs on the default channel with no nodes around me but I am unable to transmit.

I just received a T Deck Pro from a seller on ebay and was working fine for a while. Ended up dropping it twice back to back on concrete trying to work on something else. Screen is now paused without any change from screen taps or the buttons. (Only just found out about the buttons after looking up how to fix this lol) is something just disconnected inside? Does anyone have an easy way to pull off the back? I realize the Pro already has problems with the E Ink screen refreshing I was dealing with that out the box but this seems like the drops messed something up internally. Any help is appreciated thx

I’m designing a controller-style Meshtastic handheld. Haven’t printed it yet would love feedback before the first print!

First image is the look I’m aiming for; the others are current CAD renders.

Spin the 3D model, look inside, and grab the prototype print files + Amazon build list:

Hi, a while back I posted about my Meshtastic hardware project. It uses Google’s Yamnet sound recognition model with over 500 sound classes. The hardest part was to pack the fairly large model onto an ESP32 chip. On the device you can configure pretty much anything. You can define sounds that get alerted to your Meshtastic device. You can group sounds and a group triggers an alert. You can record scenes, eg someone cooking in the kitchen. Next time someone is cooking in the kitchen and the sound fingerprint matches to a certain degree, you receive an alert.

The device only works on private channels.

Sound classes (sound in text form :)) are super useful for Meshtastic:

- You want to know if something is happening in your chicken coop,
- You want to be alerted if people or animals are in your campground,
- You want to use your Meshtastic device as baby monitor (which I do),
- You want to be alerted if a vehicle is at the gate.

This project will be open source hardware and firmware. You can learn more and get updates on the project here:

Hey everyone,

We know some of you have been waiting for the Wio Tracker L2 Pro for a while — thank you so much for your patience, feedback, and support along the way!

Good news: Wio Tracker L2 Pro is finally ready for pre-order (15% OFF early bird price)! 🎉

Built with the mesh community in mind, L2 Pro brings a bigger touchscreen experience, external antenna support, a 3000mAh battery, and support for Meshtastic and other firmware projects.

A big thank you to everyone who followed this journey, shared ideas, and helped us make L2 Pro better. We can’t wait to see what you’ll build, test, and explore with it.

Let us know what you think!

The FBI, in coordination with the U.S. Attorney's Office for the Northern District of California, arrested a former employee of a San Francisco super-intelligence company for allegedly installing a covert audio recording device inside a secure executive conference room. The device was positioned to capture sensitive, nonpublic company communications.

Went to go check out where the antenna was made and it’s by this Meshtastic company.

Interesting what are y’all’s thoughts are?

Got my first node set up and am figuring it out. Cool little hobby to get into. Surprisingly there’s more nodes around me than I thought!

I’ve been beta testing Seeed’s Wio Tracker L2 Pro for the last few days, on EU_868 LONG_FAST. Mine is a pre-production unit, so the case in my photos isn’t final.

Specs: ESP32-S3 + SX1262, 3.2" touchscreen, GPS with ceramic antenna, 3000 mAh battery, microSD, Grove, USB-C. Runs MeshtasticUI.

Pros

• Works fully standalone. Chats, nodes, channels and network settings are all on the screen, no phone needed.
• Small, about the size of the screen. The antenna folds flat at 90° so it’s easy to carry.
• Offline maps from the SD card work fine. GPS got a fix in about a minute in open field.
• The Tools menu (Mesh Detector, Signal Scanner, Trace Route, packet log) is great if you like checking coverage.
• Screen is readable in direct sunlight.
• About 28 h of battery with the mesh active and the screen off most of the time.

Cons

• Entering BLE config mode isn’t obvious.
• Beta firmware had a few bugs. Most were fixed soon after I reported them, but it’s not final.

I wrote a longer review with internal and menu screenshots here: https://myembeddedstuff.com/wio-tracker-l2-pro-review

Ask me anything about it and I’ll check.

This rugged node from RAKwireless is IP67 dust and water rated, with improved GPS, a 3200 mAh battery, built-in buzzer alerts, and Meshtastic preloaded. Charge it, pair it, and you're on the mesh.

Available in Mint or Bone White for $84.97. Shipping begins October 22.

I am just getting into it but I found there's a telegram chat with some folks who are setting up meshtastic in Newfoundland. I'm hoping posting here may catch a few people who are interested and didn't know we're here!
