ESP32-C3 is a development board for IoT applications. Base on esp32-C3, which is open-source RISC-V architecture. The development board can act as a WIFI node easily, at the same time it can use Bluetooth to communicate. OLED displays have some advantages of being lightweight and working well under low-temperature environment, and it also saves energy, which can work for a long-time.
