Cocket Nova CH552 Dev Board Features USB-C Programming and Versatile GPIO Options

Based on the WCH CH552G 8-bit microcontroller the Cocket Nova CH552 Dev Board is a low-cost development board with an enhanced E8051 core clocked at 24MHz. designed for beginners and hobbyists, this compact and cost-effective development board features a USB Type-C interface for power and programming. Additional option include s 17 GPIO pins (shared with USB, LEDs, and boot buttons), 2 PWM outputs, 4 ADC channels, and 6 capacitive touch channels for up to 15 buttons and much more.

The board also has easy expansion capabilities with Qwiic/STEMMA QT connectors. All these features make this device useful for applications including educational purposes, low-power IoT devices, and simple sensor-based projects, where a cost-effective solution with minimal features is sufficient.

Previously we have written various ICs and development boards that are powered by MCUs designed and developed by WCH including LANA TNY-CH32V203, Sipeed Tang Mega 138K, the Adafruit CH552 QT, and much more feel free to check those out if you are interested in the topic.
