M5Stack Developer board M5stamp C3U Mate with pin headers

The M5Stack Stamp C3U is based on a 32-bit RISC-V microcontroller with a frequency of 160 MHz. With 400 KB of RAM and 4 MB of onboard flash memory, it is suitable for a variety of applications. The Stamp C3U supports WiFi and Bluetooth 5.0, as well as Bluetooth Mesh functionality. It is compatible with the UIFlow graphical programming platform, is script-free, offers cloud push capabilities, and is fully compatible with Arduino, MicroPython, ESP32-IDF, and other mainstream development platforms for quickly creating various applications. The difference between the C3U and the C3 Mate is that the C3U does not have a built-in USB download chip. The C3U uses the USB serial interface from the ESP32-C3 for downloading.
