MicroDev microC3
by MicroDev
Introducing MicroDev microC3 dev-board based on Espressif’s 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.

- Blue led and two NeoPixels.
- Castellated pinout.
- Onborad 700mA, 3.3V LDO.
- Stemma-QT/Qwiic connector.
- External Flash 4MB.
Specifications
- Wi-Fi 802.11b/g/n, 1T1R mode data rate up to 150Mbps.
- BLE 5.0 and rate support: 125Kbps, 500Kbps, 1Mbps, 2Mbps.
- ESP32-C3 chip, 32-bit RISC-V single-core processor.
- UART/PWM/GPIO/ADC/I2C/I2S interface, temperature sensor, pulse counter.
- Multiple sleep modes, deep sleep electric current is less than 5uA.
- STA/AP/STA+AP mode and mix mode.
- USB port local upgrade and remote firmware upgrade (FOTA).
- Secondary development, integrated Linux development environment.

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. These releases are even newer than the development release listed above. Try them if you want the absolute latest and are feeling daring or want to see if a problem has been fixed.
Previous Versions of CircuitPython
All previous releases of CircuitPython are available for download from Amazon S3 through the button below. For very old releases, look in the OLD/ folder for each board. Release notes for each release are available at GitHub button below.
Older releases are useful for testing if you something appears to be broken in a newer release but used to work, or if you have older code that depends on features only available in an older release. Otherwise we recommend using the latest stable release.
