CH522G programmer PRGMR-PC100

Overview

CH522G programmer, the information comes from the DIY programmer forum. The PCB was redrawn based on the schematic shared by the forum master and verified successfully. The speed is faster than CH341A.

You can add the chip yourself

without soldering the IC holder. The holder is also a CH552G development board. The information downloaded from the forum is shared in the attachment. Press and hold BOOT1 to power on and enter download mode. I won’t go into details about the specific download process. If you don’t know how, please refer to the tutorials in other projects.
