M5STAMP-C3 ESP32 Miniature Module

M5Stack offers a more secure way to answer Bluetooth security concerns by combining RSA-3072-based secure boot and the AES-128-XTS-based Flash encryption, making it optimal for industrial IoT equipment collecting sensor data within a factory or a building.

The Stamp-C3 is based on a 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 use-cases involving connected devices. The Stamp-C3 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. The exceptional heat resistance plastic enclosure is sustained at a higher operating temperature.
