Description

The Seeed Studio XIAO ESP32-C3 is a small thumb-sized 21mm x 17.5mm (0.83in x 0.69in) microcontroller board with WiFi (2.4GHz 802.11IEEE 802.11 is a set of protocol standards that define communication for a Wireless Local Area Network (WLAN). In order for WiFi to work between different devices, they all need to agree on how they are going to communicate. The current version of the standard is IEEE 802.11-2007, with many amendments such as 802.11a, 802.11b, 802.11g, and 802.11n.b/g/n up to 150Mbps) and Bluetooth 5 (BLEBluetooth Low Energy).

The board contains an ESP32-C3 SoCSystem On a Chip (Datasheet PDF) with an RISC-VReduced Instruction Set Computer 5 (RISC-V, pronounced "risk-five") is the 5th generation of processors built on RISC principles, with a modular, extensible, open standard Instruction Set Architecture (ISA) provided under royalty-free open-source licenses. 32-bit Single-Core 160MHz processor, 4MB of flash memory, USB-C connector, reset and boot buttons, battery charge status LEDLight Emitting Diode, and uFL connector for an external antenna. A uFL antenna comes with the board that provides a wireless connection over 100m.

There are two solder pads on the back of the board (labeled BAT) for connecting a single-cell LiPoLithium Polymer/Li-ionLithium-ion battery. The board has a battery charge chip that allows you to charge the battery when power is applied to the USB and a charge status LED.
