M5Stamp C3 RISC-V board supports WiFI 4, Bluetooth 5.0 Long Range and 2 Mbps bitrate

M5Stamp C3

It was only last month that M5Stack launched the M5Stamp Pico module based on an ESP32-PICO-D4 SiP and heat-resistant plastic shell, but M5Stamp C3 board is already out with most of the same specifications and features but an ESP32-C3 RISC-V SoC replaces the ESP32 dual-core Xtensa processor. M5Stamp C3 offers WiFi 4 and Bluetooth 5.0 with high bitrate and long-range connectivity and comes with the same heat-resistant plastic shell, but the company also highlights the RSA-3072-based secure boot and the AES-128-XTS-based flash encryption as a more secure way to address Bluetooth security concerns. M5Stamp C3 specifications: WiSoC – ESP32-C3FH4 32-bit single-core RISC-V processor @ up to 160 MHz, with 384KB ROM, 400KB SRAM, 8KB RTC SRAM, 4MB embedded flash, WiFI and Bluetooth Connectivity 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, […]
