This ESP32-C3 board delivers maximum performance in an ultra-compact form factor: Featuring an integrated 0.42″ OLED display (72×40 pixels), a USB-C connector, and a powerful RISC-V microcontroller, it is the perfect choice for makers, developers, and IoT projects.
The compact board offers Wi-Fi and Bluetooth Low Energy (BLE 5.0), multiple GPIO pins, and full compatibility with Arduino, MicroPython, CircuitPython, and ESP-IDF. This makes it easy to integrate sensors, displays, and other modules.
Thanks to the built-in display, data, status messages, or debugging information can be shown directly — ideal for prototyping, smart home devices, or portable electronics.
Setup instructions and resources are available on GitHub.
The package includes the board and header pins, which can be soldered if required. Delivery comes in a durable plastic storage box.
