Infineon MiniWiggler 3-in-1 Downloader

Downloader for Infineon series chips suitable for the National Undergraduate Intelligent Vehicle Competition

The schematic diagram references the full PCB structure of the Infineon official development board's onboard downloader

, using copper pillars for assembly, conforming to JLC free-to-use technology. For free-to-use, please select 1.0mm for easy cutting.
It supports DAP and JTAG downloads, and also has a separate serial port interface with overcurrent protection, ESD protection, and support for external I/O voltage.
There is an RGB light indicating the working status: red indicates power failure of host computer control/USB not connected to the computer/load overcurrent protection/no external power supply; green indicates connection status; blue indicates simulation.
The upper right corner switch toggles the serial port definition for debugging the core board.
The first switch in the lower left corner toggles the I/O voltage to built-in 3.3V/external power supply.
The second switch in the lower left corner toggles JTAG download mode/DAP download mode (different interfaces are required; JTAG and DAP download interfaces are separate).

Assembly requires a bill of materials:
M2x3mm screws -----------4
M2x3 double-through knurled screws with the same pin ----- 4
M2x6+3 single-through knurled screws with the same pin --

Note: For simple bull mount mounting, the leads need to be cut. Firmware is attached.

You can purchase the finished product using FT_Prog. [Link: https://m.tb.cn/h.g5u02IG?tk=oChXWzqgCRQ](https://m.tb.cn/h.g5u02IG?tk=oChXWzqgCRQ)
