Adafruit unveils QT Py ESP32-C3 development board with Wi-Fi and Bluetooth support

Adafruit has been famous for developing miniature development boards for IoT applications, such as the Adafruit QT Py dev boards powered by RP2040 and SAMD21. Adafruit, yet again, comes with another QT Py with ESP32-C3 module that supports Wi-Fi and Bluetooth Low Energy wireless connectivity. As a RISC-V microcontroller onboard, the hardware gives a lot of flexibility to new developers to explore the vast capabilities of a RISC-V process.

As mentioned earlier, the ESP32-C3 module is based on the RISC-V open-standard instruction set architecture with a single-core 32-bit RISC-V processor core, clocked at a frequency of up to 160MHz. The key highlight of the microcontroller device is the wireless connectivity support for a complete Wi­-Fi subsystem that complies with IEEE 802.11b/g/n protocol and supports Station mode, SoftAP mode, SoftAP and Station mode, and promiscuous mode. On the Bluetooth side, the Bluetooth LE subsystem supports features of Bluetooth 5 and Bluetooth mesh.
