About the Esp rust board

Esp rust board is an open source ESP32 PCB design by esp-rs, published on GitHub. It is a 2-layer board measuring 22.9 × 63.5 mm, with 48 components from 27 distinct parts.

Its main chip is the ESP32-C3-MINI-1, from the ESP32 family. Other key parts include the SHTC3, ICM-42670-P, SY8088 and MCP73831T-2ACI/OT. By type, the board carries 16 resistors, 13 capacitors, 9 diodes, 5 ICs, 2 switches and 1 transistor.

It belongs with the sensors, dev boards & breakouts and iot & wireless designs in this gallery.

Esp rust board: common questions

What microcontroller does the Esp rust board use?

The Esp rust board is built around the ESP32-C3-MINI-1, from the ESP32 family.

How big is the Esp rust board?

The Esp rust board measures 22.9 × 63.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Esp rust board?

48 components, from 27 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Esp rust board design files?

From the esp-rs/esp-rust-board repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Esp rust board design in my own project?

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

Can I test firmware for the Esp rust board 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.
