PRODUCT DETAILS

Description

M5Stamp C3U is a cutting-edge development board featuring the ESPRESSIF ESP32-C3 RISC-V MCU. Equipped with Wi-Fi 5 (LE) connectivity, this board is designed for a wide range of applications, including home appliances and industrial automation. With top-of-the-line security features such as RSA-3072-based secure boot and AES-128-XTS-based flash encryption, the M5Stamp C3U ensures robust protection for your data. Its compact size and powerful functionality make it an ideal choice for various IoT scenarios.

The M5Stamp C3U is built around a 32-bit RISC-V microcontroller, operating at a maximum clock frequency of 160 MHz. With 400 KB of internal RAM and 4 MB Flash memory, it provides ample resources to support diverse connected device use cases. This versatility enables seamless integration into a wide range of projects and applications.

Furthermore, the M5Stamp C3U features an exceptional heat-resistant plastic enclosure, allowing it to operate reliably even at higher temperatures. This ensures the board's durability and stability, making it suitable for demanding environments.

The M5Stamp C3U combines the power of the ESPRESSIF ESP32-C3 RISC-V MCU, Wi-Fi 5 (LE) connectivity, advanced security features, and a compact form factor, making it a highly adaptable and capable development board. Whether you're working on smart home appliances or industrial automation solutions, the M5Stamp C3U provides the performance and reliability you need for your IoT projects.

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

• 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!

Program Download/Notes

Enter the program download mode operation:
1. Long press the center button (G9) of STAMP C3U under power failure condition.
2. Connect to the computer, after the port is successfully identified, program burning.
USB CDC enabled:
By default, USB CDC is not enabled, the serial port output started by C3U will be output through UART0, if you need to output through USB, please use IDE to make it USB CDC before downloading the program option enabled. (Arduino users can enable it through Tools->USB CDC on Boot-Enabled, IDF users please refer to ESP IDF official documentation.)
