´╗┐Description:

The newly M5Stamp C3U featuring ESPRESSIF ESP32-C3 RISC-V MCU, with Wi-Fi and Bluetooth 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, ESP32-C3 offers a more secure way to answer the Bluetooth security concerns. The compact size and powerful functions, make it applicable for multiple IoT scenarios.

The M5Stamp C3U is based on 32-bit RISC-V microcontroller, 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 full Bluetooth 5.0 long-range (LR) support including long-range and mesh networking functions and achieves building devices with great coverage and improved usability. Furthermore, the exceptional heat resistance plastic enclosure is sustained at a higher operating temperature.

Product Features:

MULTIPLE STYLE:
Three types soldering options are available (SMT, DIP, flywires);
High-temperature resistant plastic enclosure, Peak temperature = 230Ôäâ;

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:
Arduino0, 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)

Download mode:

Enter program download mode:
1. Long press on the center button of the M5Stamp C3U when the power is off (G9)
2. After connecting to the computer and successfully identifying the port, it starts flashing programs.
