Seeed Studio XIAO ESP32C3 – tiny MCU board with Wi-Fi and BLE, battery charge supported, power efficiency and rich Interface

Description

Seeed Studio XIAO ESP32C3 featuring ESP32C3 carries a complete Wi-Fi system along with Bluetooth Low Energy function. With its exquisite design and WiFi+BT ability, it’s perfect for various IoT controlling scenarios and complex carriable applications.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.

Features:

1. Outstanding RF performance,Powerful ESP32-C3 SoC and U.FL antenna provided that supports WiFi/Bluetooth connection over 100m.
2. Thumb-size Design, 21 x 17.5mm overall dimension, portable and lightweight.
3. Low power consumption, Lowest as 44 μA (deep sleep mode), with 4 working modes available.
4. Onboard battery charge IC, Supports battery charging, great for various wearable scenarios and wireless IoT applications.
5. Ready for productization,  Single-sided components design, easily integrated into other boards and Seeed provides Fusion Service for rapid production.
