It features the following integrated components:

ESP32-C3 SoC (RISC-V 160MHz single core, 400KB SRAM, Wi-Fi, Bluetooth)
on board Grove connector
USB-C connector for power and communication (on board serial)
optional 18340 Li-ion battery holder
LED

Hardware

This board is based on the ESP32-C3 with 4MB of flash, WiFi and BLE support. It has an USB-C port for programming and debugging, integrated battery charging and an Grove connector.
