ESP32-C3-0.42LCD
by 01space
The ESP32-C3-0.42LCD is an ESP32 C3 / RP2040 Raspberry Pi Pico Development board with 0.42 inch LCD risc-v WiFi Bluetooth.
ESP32-C3 is a low-cost microcontroller from Espressif that supports 2.4 GHz Wi-Fi and Bluetooth® Low Energy ( Bluetooth 5 (LE)).Use RISC V as the core. There’s a minimum number of pins on this chip, it’s specifically designed to be low cost and for simpler projects than ESP32-Sx or ESP32 classics with their large number of GPIO. Think of it more as an intended replacement to the ESP8266 than to the ESP32! It has built-inUSB-to-Serial, but not native USB - it cannot act as a keyboard or disk drive. The chip used here has 4MB of Flash memory, 400 KB of SRAM.
The ESP32-C3 integrates a rich set of peripherals, ranging from UART, I2C, I2S, remote control peripheral, LED PWM controller, general DMA controller, TWAI controller, USB Serial/JTAG controller, temperature sensor, and ADC. It also includes SPI, Dual SPI, and Quad SPI interfaces. There is no DAC or native capacitive touch.
With its state-of-the-art power and RF performance, this SoC is an ideal choice for a wide variety of application scenarios relating to the Internet of Things (IoT), wearable electronics, and smart homes.

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.
