ESP32 C3 Mini Dev Board

The ESP32-C3 is powered by a RISC-V 32-bit single-core processor with a clock frequency of up to 160 MHz. It has 22 programmable GPIO pins, built-in 400 KB SRAM, and supports multiple external flashes through SPI, Dual SPI, Quad SPI and QPI interfaces to meet the functional requirements of various IoT products. In addition, the high temperature resistance of ESP32-C3 also makes it an ideal choice for lighting and industrial control fields.

The ESP32-C3 integrates 2.4 GHz Wi-Fi and long-range Bluetooth 5 (LE) to help build IoT devices with extended range and enhanced RF performance. It also supports Bluetooth Mesh (Bluetooth Mesh) protocol and Espressif Wi-Fi Mesh to maintain excellent RF performance at higher operating temperatures.

ESP32-C3 supports secure boot based on RSA-3072 algorithm and flash encryption based on AES-128-XTS algorithm to ensure secure device connection; innovative digital signature module and HMAC module to ensure device identity security; hardware accelerator supporting encryption algorithm ensures Devices securely transmit data on local networks and the cloud.
