Key features of ESP32-C3-MINI development board

  • ESP32-C3 is a secure, stable, low-power, low-cost IOT chip equipped with RISC-V32-bit single-core processor, supporting 2.4GHz Wi-Fi and Bluetooth 5 (LE). Provide industry-leading RF performance, complete security mechanism and rich memory resources for iot products.
  • ESP32-C3's dual support for Wi-Fi and Bluetooth 5 (LE) reduces the difficulty of device distribution and is suitable for a wide range of iot application scenarios.
  • ESP32-C3 is equipped with RISC-V 32-bit single-core processor, clock rate up to 160 MHz. It has 22 programmable GPIO pins and 400 KB built-in SRAM, and supports multiple external flash interfaces through SPI, Dual SPI, Quad SPI, and QPI, meeting the functional requirements of various iot products. In addition, the high temperature resistance of the ESP32-C3 also makes it ideal for lighting and industrial control.
  • The ESP32-C3 integrates 2.4GHz Wi-Fi and Bluetooth 5 (LE) with long range support to help build iot devices with greater coverage and RF performance. It also supports the Bluetooth Mesh protocol and Wi-Fi Mesh, maintaining excellent RF performance at higher operating temperatures.
  • ESP32-C3 supports secure startup 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 ensure device identity security; Hardware accelerators that support encryption algorithms ensure that devices securely transfer data on local networks and in the cloud.
  • ESP32-C3 follows the mature Internet of Things development framework ESP-IDF. ESP-IDF has successfully enabled hundreds of millions of iot devices and has gone through rigorous testing and release cycles. Based on its mature software architecture, familiarity with apis and tools will make it easier for developers to build or migrate ESP32-C3 applications.
  • The ESP32-C3 also works in slave mode, providing wi-Fi and Bluetooth LE connectivity to the external host MCU through ESP-AT and ESP-Hosted SDK.
