ESP32-C3 is a single-core Wi-Fi and Bluetooth 5 (LE) microcontroller SoC, based on the open-source RISC-V architecture. It strikes the right balance of power, I/O capabilities, and security, thus offering the optimal cost-effective solution for connected devices. The availability of Wi-Fi and Bluetooth 5 (LE) connectivity not only makes the device's configuration easy but also facilitates a variety of use cases based on dual connectivity.


  • ESP32-C3 integrates a 32-bit core RISC-V microcontroller with a maximum clock speed of 160 MHz. With 22 configurable GPIOs, 400 KB of internal RAM, and low-power-mode support, it can facilitate many different use cases involving connected devices. The MCU comes in multiple variants with integrated and external flash availability. The high-temperature support makes it ideal for industrial and lighting use cases.
  • Wi-Fi and Bluetooth 5 (LE) with long-range (LR) support help build devices with great coverage and improved usability. ESP32-C3 continues to support Bluetooth LE SIG Mesh and Espressif Wi-Fi Mesh. Furthermore, the solid RF performance of ESP32-C3 is sustained at a higher operating temperature.
  • ESP32-C3 ensures that the availability of features, such as the RSA-3072-based secure boot and the AES-128/256-XTS-based flash encryption, can be used to build connected devices securely. The innovative digital signature peripheral and the HMAC peripheral provide a secure device identity for applications. Hardware acceleration support for cryptographic algorithms ensures good performance for secure communication both in a local network and with the Cloud.
  • ESP32-C3 is supported through Espressif’s open-source ESP-IDF which already powers millions of devices in the field. This ensures the availability of a robust SDK and tools, as well as an easy application migration path for developers. ESP32-C3 can also be used with an external host MCU, using ESP-AT and ESP-Hosted solutions.
