DevLab: CH552 Multi-Protocol Programmer Module

The CH552 Multi-Protocol Programmer Module is a versatile and compact programming tool designed for developers and hobbyists working with various microcontroller architectures. It supports multiple programming protocols, including SWD, JTAG, UPDI, and USBasp, making it an ideal choice for programming AVR, ARM, and CPLD devices.

Quick Setup

Features

• USB Full-Speed (CDC/HID)
• Voltage selector: 3.3V / 5V
• SWD / JTAG / UPDI / USBasp support
• Works with popular tools (avrdude, OpenOCD, Quartus, etc.)

Warning:
This programmer requires specific firmware depending on the protocol:

• AVR: USBasp & UPDI
