Rust ESP Board

Welcome to the Rust ESP Development board project. This repository contains everything you will need to build the board yourself.

Where to buy

• ESP32-C3-DevKit-RUST-1
• AliExpress Espressif Official Store
• Mouser Electronics (Note that at least when ordering from the UK and seemingly EU and Europe, if you choose to order through Mouser there is long process instigated by email post-checkout to fill out and then electronically sign or fax export declaration forms which can add significant delay)

I2C Peripherals

This board includes the following peripherals over the I2C bus:

I2C Bus Connection

I/Os

The following devices are connected through GPIO:

Power

• USB type-C (no PD compatibility).
• Li-Ion battery charger - MCP73831T-2ACI/OT, it charges up to 4.2V.
  • Recommendation: MCP73831T-2ACI/OT does not provide battery protection for over-current or over-discharge. For the battery (Li-Ion or Li-Po), it's recommended the ones with embedded protection
  • Limitation: reading the battery voltage is not supported.
