This repository contains everything you will need to build the board yourself.\n\n## Where to buy\n\n* [ESP32-C3-DevKit-RUST-1](https://www.espressif.com/en/products/devkits)\n* [AliExpress Espressif Official Store](https://www.aliexpress.com/item/1005004418342288.html)\n* [Mouser Electronics](https://www2.mouser.com/ProductDetail/Espressif-Systems/ESP32-C3-DevKit-RUST-1?qs=4ASt3YYao0WvXOj9TGjU2A%3D%3D)\n\n## Ferrous Systems Training\n\n* [Training Book: Explore the power of Rust on the new Espressif board](https://github.com/esp-rs/std-training)\n  * [Training Material](https://esp-rs.github.io/std-training/)\n\n## Project Specification\n\nThis board is based on the ESP32-C3, and includes sensors, LEDs, buttons, a battery charger, and USB type-C connector.\n\n### SoC Features\n\n* IEEE 802.11 b/g/n-compliant\n* Bluetooth 5, Bluetooth mesh\n* 32-bit RISC-V single-core processor, up to 160MHz\n* 384 KB ROM\n* 400 KB SRAM (16 KB for cache)\n* 8 KB SRAM in RTC\n* 22 × programmable GPIOs\n* 3 × SPI\n* 2 × UART\n* 1 × I2C\n* 1 × I2S\n* 2 × 54-bit general-purpose timers\n* 3 × watchdog timers\n* 1 × 52-bit system timer\n* Remote Control Peripheral (RMT)\n* LED PWM controller (LEDC)\n* Full-speed USB Serial/JTAG controller\n* General DMA controller (GDMA)\n* 1 × TWAI®\n* 2 × 12-bit SAR ADCs, up to 6 channels\n* 1 × temperature sensor\n\nFor the complete description, see the [ESP32-C3 Datasheet](https://www.espressif.com/sites/default/files/documentation/esp32-c3_datasheet_en.pdf).\n\n![Diagram](assets/rust_board_v1.2_diagram.png)\n\n### I2C Peripherals\n\nThis board includes the following peripherals over the I2C bus:\n\n| Peripheral               | Part number | Reference                                                                                                      | Crate                                     | Address |\n| ------------------------ | ----------- | -------------------------------------------------------------------------------------------------------------- | ----------------------------------------- | ------- |\n| IMU                      | ICM-42670-P | [Datasheet](https://invensense.tdk.com/download-pdf/icm-42670-p-datasheet/)                                    | [Link](https://crates.io/crates/icm42670) | 0x68    |\n| Temperature and Humidity | SHTC3       | [Datasheet](https://www.mouser.com/datasheet/2/682/Sensirion_04202018_HT_DS_SHTC3_Preliminiary_D2-1323493.pdf) | [Link](https://crates.io/crates/shtcx)    | 0x70    |\n\n#### I2C Bus Connection\n\n| Signal | GPIO   |\n| ------ | ------ |\n| SDA    | GPIO10 |\n| SCL    | GPIO8  |\n\n### I/Os\n\nThe following devices are connected through GPIO:\n\n| I/O Devices | GPIO  |\n| ----------- | ----- |\n| WS2812 LED  | GPIO2 |\n| LED         | GPIO7 |\n| Button/Boot | GPIO9 |\n\n### Power\n\n* USB type-C (*no PD compatibility*).\n* Li-Ion battery charger - MCP73831T-2ACI/OT, it charges up to 4.2V.\n  * 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\n  * Limitation: reading the battery voltage is not supported.\n\n### Pin Layout\n\n![Pin Layout](assets/rust_board_v1_pin-layout.png)\n\n\n#### Left Side\n\n| Pin Number | Description  | SoC        |\n| ---------- | ------------ | ---------- |\n| 1          | Reset        | EN/CHIP_PU |\n| 2          | 3V3          |            |\n| 3          | N/C          |            |\n| 4          | GND          |            |\n| 5          | IO0/ADC1-0   | GPIO0      |\n| 6          | IO1/ADC1-1   | GPIO1      |\n| 7          | IO2/ADC1-2   | GPIO2      |\n| 8          | IO3/ADC1-3   | GPIO3      |\n| 9          | IO4/ADC2-0   | GPIO4      |\n| 10         | IO5/ADC2-1   | GPIO5      |\n| 11         | IO6/MTCK     | GPIO6      |\n| 12         | IO7/MTDO/LED | GPIO7      |\n| 13         | IO9/LOG      | GPIO8      |\n| 14         | IO21/U0RXD   | GPIO21     |\n| 15         | IO20/U0TXD   | GPIO20     |\n| 16         | IO9/BOOT     | GPIO9      |\n\n#### Right Side\n\n| Pin Number | Description | SoC    |\n| ---------- | ----------- | ------ |\n| 1          | VBAT        |        |\n| 2          | EN [1]      |        |\n| 3          | VBUS [2]    |        |\n| 4          | NC          |        |\n| 5          | NC          |        |\n| 6          | NC          |        |\n| 7          | NC          |        |\n| 8          | NC          |        |\n| 9          | IO18/USB_D- | GPIO18 |\n| 10         | IO19/USB_D+ | GPIO19 |\n| 11         | IO8/SCL     | GPIO8  |\n| 12         | IO10/SDA    | GPIO10 |\n\n  * [1] Connected to LDO enable pin*\n  * [2] Connected to USB 5V*\n\n## Project KiCad Libraries\n\n* [ESP32C3](https://github.com/espressif/kicad-libraries)\n\n## Board Design\n\nTop\n\n![TOP](assets/esp-rust-board_top.jpg)\n\nBottom\n\n![BOT](assets/esp-rust-board_bot.jpg)\n\n## Bill of Material\n\n[Interactive BOM](https://esp-rs.github.io/esp-rust-board/)\n\n## Case\n\n[Case 3D Printing Model](https://www.printables.com/model/288200-minimalistic-case-for-esp32-c3-devkit-rust-1)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fesp-rs%2Fesp-rust-board","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fesp-rs%2Fesp-rust-board","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fesp-rs%2Fesp-rust-board/lists"}
