€8.30
Tax included

Compact M5Stamp C3U module based on ESP32-C3 RISC-V (160 MHz, 4 MB Flash). Features WiFi, Bluetooth 5 (LE), USB Type-C and 14 GPIOs. Heat-resistant for SMT soldering, ideal for industrial IoT.

Quantity

The M5Stamp C3U is a cost-effective, minimal core board based on the 32-bit RISC-V ESP32-C3 microcontroller. Operating at up to 160 MHz with 400 KB SRAM and 4 MB Flash, it supports 2.4 GHz Wi-Fi and Bluetooth 5 (LE). The board features a high-temperature resistant plastic housing capable of withstanding reflow soldering temperatures (230°C), making it suitable for mass production.

Equipped with secure boot (RSA-3072) and flash encryption, the Stamp-C3U is optimized for industrial IoT applications such as home automation and factory sensor data collection. It supports multiple mounting styles (SMT, DIP, or flying leads) and can be programmed via Arduino IDE, ESP-IDF, or PlatformIO.
