About the Meshtastic v0 PCB

Meshtastic v0 is an open source ESP32 PCB design by luthfai, published on GitHub. It is a 2-layer board measuring 71 × 46 mm, with 74 components from 38 distinct parts.

Its main chip is the ESP32-S3-WROOM-1, from the ESP32 family. Other key parts include the DM-OLED096-636, ATGM336H, TPS62046DGQR, HT-RA62 and Lever Switch TMHU26. By type, the board carries 23 resistors, 22 capacitors, 10 ICs, 8 diodes, 4 transistors and 4 connectors.

It belongs with the iot & wireless, rf & radio and power & battery designs in this gallery.

From the project

Phones stop working the moment you leave coverage. meshthingy doesn't need coverage — it is the network.

Phones stop working the moment you leave coverage. meshthingy doesn't need coverage — it is the network.

Each board is one node in a self-healing Meshtastic mesh. Nodes talk directly to each other over licence-free LoRa radio, and every node automatically relays traffic for its neighbours. Two units give you a private long-range walkie-talkie for text; a handful scattered across a valley, a campsite, a ridgeline, or a city block give everyone in that area a shared messaging network that keeps working when nothing else does.

Meshtastic v0: common questions

What microcontroller does the Meshtastic v0 use?

The Meshtastic v0 is built around the ESP32-S3-WROOM-1, from the ESP32 family.

How big is the Meshtastic v0 PCB?

The Meshtastic v0 measures 71 × 46 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Meshtastic v0?

74 components, from 38 distinct parts. The full bill of materials is listed on this page.

Where can I download the Meshtastic v0 design files?

From the luthfai/meshthingy_v0 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Meshtastic v0 design in my own project?

The repository has no license, so all rights stay with luthfai. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Meshtastic v0 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
