by Ai-Thinker

Image of Board

This is an entry-level development board based on Espressif ESP32-C3 SoC, which is equipped with a RISC-V 32-bit single-core processor, operating frequency up to 160 MHz, supports secondary development without using other microcontrollers or processors. The ESP32-C3 is an highly integrated low power Wi-Fi and Bluetooth system-level chip (SoC), designed for various applications such as internet of things (IoT), mobile devices, wearable electronics, smart home, etc.

Features

  • Onboard ESP-C3-32S module that comes with a PCB antenna
  • Onboard CH340, USB to UART converter
  • RGB 3-in-1 LED, convenient for secondary development
  • USB port for power input, firmware programming, or UART debugging
  • 2x15pin extension headers, breakout all the I/O pins of the module
  • 2x keys, used as reset or user-defined

Specifications

  • Complete Wi-Fi 802.11b/g/n, 1T1R mode data rate up to 150Mbps
  • Support BLE5.0 and rate support: 125Kbps, 500Kbps, 1Mbps,2Mbps
  • Onboard ESP32-C3 chip, 32-bit RISC-V single-core processor, supports a clock frequency of up to 160 MHz, with 400 KB SRAM, 384 KB ROM, 8KB RTC SRAM
  • Support UART/PWM/GPIO/ADC/I2C/I2S interface, temperature sensor, pulse counter
  • SMD-38 package
  • Integrated Wi-Fi MAC/ BB/RF/PA/LNA/BLE
  • Support multiple sleep modes, deep sleep electric current is less than 5uA
  • UART rate up to 5Mbps
  • Support STA/AP/STA+AP mode and mix mode
  • Support Smart Config (APP)/AirKiss (WeChat) of Android and IOS One-click network configuration
  • Support UART port local upgrade and remote firmware upgrade (FOTA)
  • General AT commands can be better understand
  • Support secondary development, integrated Linux development environment
  • ESP-C3-32S module acquiesce in using the built-in 2MByte Flash, meanwhile support external Flash version

CircuitPython 7.1.0-beta.1

This is the latest unstable release of CircuitPython that will work with the ESP-C3-32S.

Unstable builds have the latest features but are more likely to have critical bugs.

Absolute Newest

Every time we commit new code to CircuitPython we automatically build binaries for each board and language. The binaries are stored on Amazon S3, organized by board, and then by language. Try them if you want the absolute latest and are feeling daring or want to see if a problem has been fixed.

Past Releases

All previous releases are listed on GitHub, with release notes, and are available for download from Amazon S3. They are handy for testing, but otherwise we recommend using the latest stable release. Some older GitHub release pages include the same binaries for downloading. But we have discontinued including binaries as assets on newer release pages because of the large number of files for each release.
