About this item

The WeAct Studio CH552T Mini Core Board is a compact and cost-effective development platform based on the WCH CH552T microcontroller. Built around an enhanced MCS-51 (8051-compatible) core, the CH552T offers a modern twist on a classic architecture, making it an excellent learning tool for embedded systems education, USB device development, and low-cost product prototypes. Running at up to 24 MHz, the CH552T integrates 16KB of flash memory and 1KB of RAM, suitable for lightweight embedded applications. The standout feature of this chip is its built-in USB 2.0 Full-Speed device controller, which allows easy implementation of USB HID, CDC, or custom USB classes—without requiring external USB chips. The board features a DIP20-compatible layout with a TSSOP20 package, making it breadboard-friendly and perfect for quick prototyping. Standard peripherals such as UART, SPI, PWM, ADC, and timers are available through its I/O pins. It supports development using SDCC, Keil, and WCH’s CH554Tool, offering flexible programming options. Compact, USB-capable, and easy to use, the WeAct CH552T Mini Core Board is a great entry point for students, hobbyists, and engineers working with 8051-style microcontrollers or learning USB firmware development.
