Seeed Studio XIAO Series are diminutive development boards, sharing a similar hardware structure, where the size is literally thumb-sized. The code name "XIAO" here represents its half feature "Tiny", and the other half will be "Puissant".

Seeed Studio XIAO ESP32C3 adopts new RISC-V architecture, supporting both Wi-Fi and BLE wireless connectivities. For Internet of Things applications, you will find it is flexible and suitable for all kinds of IoT scenarios.

The board equips highly-integrated ESP32-C3 SoC. The chip has been installed with a complete 2.4GHz Wi-Fi subsystem which means it supports Station mode, SoftAP mode, SoftAP & Station mode, and promiscuous mode for multiple Wi-Fi applications. It works under an ultra-low power state, also supporting features of Bluetooth 5 and Bluetooth mesh. There are 400 KB SRAM & 4 MB Flash on the chip, allowing for more programming space, and bringing more possibilities to the IoT control scenarios.
