About the Meshtastic v0-rounded PCB

Meshtastic v0-rounded is an open source ESP32 PCB design by luthfai, published on GitHub. It is a 2-layer board measuring 71 × 46 mm, with 71 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 22 capacitors, 22 resistors, 10 ICs, 7 diodes, 4 connectors and 3 transistors.

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

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-rounded: common questions

What microcontroller does the Meshtastic v0-rounded use?

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

How big is the Meshtastic v0-rounded PCB?

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

How many components are on the Meshtastic v0-rounded?

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

Where can I download the Meshtastic v0-rounded design files?

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

Can I use the Meshtastic v0-rounded 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-rounded 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.
