The Seeed Studio XIAO ESP32C3 is a compact and versatile microcontroller module powered by the ESP32-C3 SoC, featuring both Wi-Fi and Bluetooth capabilities with a U.FL antenna that supports long-range connectivity over 100 meters. It comes equipped with 11 digital I/O pins, all of which can function as PWM outputs, and 4 analogue I/O pins that can serve as ADC inputs. This module is also compatible with UART, IIC, and SPI serial communication ports. Its petite dimensions (21 × 17.5 mm) make it exceptionally portable and suitable for space-constrained projects. With an impressively low power consumption that drops to as little as 44 μA in deep sleep mode, it offers 4 different operating modes to cater to various power requirements. Additionally, it supports battery charging, rendering it ideal for wearable technology and a range of wireless IoT applications.
