Espressif’s ESP32-C3 32-bit RISC-V MCU offers a frequency of up to 160MHz and supports 2.4 GHz Wi-Fi and Bluetooth LE 5.0. The device also offers excellent radio-frequency performance, all necessary security mechanisms, and abundant memory resources that are suitable for a wide range of IoT applications. The safe, low-power and low-cost ESP32-C3 MCU has been Wi-Fi CERTIFIED by Wi-Fi Alliance for b/g/n, WPA3-Private, and WPA3-Enterprise programs.


WPA3 is the next generation of Wi-Fi security in the Wi-Fi Protected Access (WPA) technology series providing cutting-edge security protocols. WPA3 also provides more reliable authentication and improves the encryption strength of privacy protocols. WPA3 includes the WPA3-Private and WPA3-Enterprise that can be used in government, industry, or other large-scale Wi-Fi networks transmitting and receiving sensitive personal data.


ESP32-C3 has passed both the WPA3-Private and WPA3-Enterprise certifications, making the 32-bit RISC-V MCU can offer secured Wi-Fi connectivity for both individual and corporate consumers.
