Mini DAP-Link based on CH552G, costing 2.6 yuan

Overview

All contents of this project are derived from
the assembly-optimized high-speed DAP-Link (CMSIS-DAP v2) implemented by the open source CH551/2 / Cortex M0/M3/M4/M7 / WhyCan Forum (Wow Cool Developer Community)
based on the schematic diagram. The design

has been verified and can work.
The attachment contains the burning software and corresponding firmware.

The following historical changes will not be applied to the PCB. Please directly check the values on the PCB to purchase components.
This PCB is only used for principle verification

TODO: History of
current anti-backflow
Change:
Added resettable fuse
