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.
The specifications of the M5 Stamp C3 are as follows:
- ESP32-C3FH4 32-bit single-core RISC-V processor @160 MHz, with 384KB ROM, 400KB SRAM, 8KB RTC SRAM, 4MB embedded flash
- 2.4 GHz WiFi 4, 20 MHz and 40 MHz bandwidth, IEEE 802.11 b/g/n protocol, up to 150 Mbps
- Bluetooth 5, Bluetooth mesh, with supports for 125 Kbps, 500 Kbps, 1 Mbps, 2 Mbps bitrate, long-range
- USB -C port for power and programming via a CH9102
- Expansion – 2.54mm pitch headers with ADC, 13x GPIO, SPI, UART, I2C, I2S, PWM, RMT, DMA, USB Serial
- 1x user button, 1x reset button, RGB Neo-Pixel
- Power: 5V @ 500mA via USB-C port
- Dimensions: 34 x 20 x 4.5mm
- Weight: 3.8 grams
