M5Stamp C3 Released Featuring 32-Bit RISK-V ESP-32C3 MCU

M5Stack’s new development board, the M5Stamp, uses an ESP-32C3 MCU. The ESP-32C3 is a RISK-5 based microcontroller with Wi-Fi 4 and Bluetooth 5 LE connectivity. The onboard RSA-3072-based secure boot and the AES-128-XTS-based flash encryption ensure that devices are connected securely. The ESP32-C3 is supported through Espressif’s open-source ESP-IDF SDK. The M5 Stamp C3 comes housed in a heat-resistant plastic casing.
