The newly M5Stamp C3U featuring ESPRESSIF ESP32-C3 RISC-V MCU, with Wi-Fi 5 (LE) connectivity, applicable for home appliances and Industrial Automation. By combining RSA-3072-based secure boot and the AES-128-XTS-based flash encryption. The compact size and powerful functions, make it applicable for multiple IoT scenarios.

The M5Stamp C3U is based on 32-bit RISC-V micro controller, and operates at a maximum clock frequency of 160 MHz. With 400 KB of internal RAM and 4 MB Flash, it can facilitate many different use cases, involving connected devices. The M5Stamp C3U provides, Furthermore, the exceptional heat resistance plastic enclosure is sustained at a higher operating temperature.

Note: If you need to use SPIFFS filesystem in Arduino IDE. Please install a patch package first.

Features

• MULTIPLE STYLE:
  • Three types soldering options are available (SMT, DIP, fly wire);
  • High-temperature resistant plastic enclosure, Peak temperature = 230℃;
• HIGH INTEGRATION:
  • M5Stamp C3 contains 5V->3.3V DC/DC design, GPIOx14;
  • USB Type C port;
  • Programmable RGB LED x1, Reset button x1, button x1;
  • 3D antenna, providing stable and reliable wireless communication.
• DEVELOPMENT PLATFORM:
  • Arduino, ESP32-IDF (UIFlow support coming soon)

Application

• DIY, Prototyping
• Industrial Automation
• Smart Home
• Wearable Devices
• Medical Devices
• Consumer Electronics

Note: The newly updated C3U shares the same features as C3, but the difference is that M5Stamp C3U without the USB download chip and the program download method is different（(The C3U uses the ESP32-C3’s built-in USB Serial for program download)）. If you are looking for a more affordable project, you can add this to your shopping list!
