XGecu TL866II Plus programmer TSOP-40A 8-bit adapter pin mapping
« on: February 07, 2025, 12:09:57 am »
 After MUCH research and frustration in looking for the exact pin-mapping between TSOP40 and DIP40 on the adapter for TL866II Plus, I was finally able to do it.
Even though the manufacturer of this programmer and its adapters states on its website that its adapters are "open source" and that its customers can make their own adapters, there was no information on the Internet that I could find regarding this specific adapter design.
 After many hours of search, I got two semi-decent images (top and bottom) of the mentioned adapter, placed them in GIMP, did some stretching/resizing and rotating to match them (I spent many hours there as well, being a beginner with GIMP).
 Finally, after spending some hours tracing each line multiple times and correcting my previous errors in tracing, I had a text file correctly matching the pins between the two different "sockets", which was late for my homemade adapter which I had wired directly (pin 1 to 1, 2 to 2, 3 to 3, etc.).

 A few days ago I got the adapter boards from AliExpress, and I have scanned them (at 300dpi which should be good enough) to share the detailed images with the world because of my own frustration of not finding them when it was urgent for me to have these adapters.
 I am also including the mapping between TSOP40 and DIP40.
 I plan to include PCB design files eventually, but as a beginner in KiCAD and EDA, I will need more time, though the 1:1 scans should make it easier now.

 The images are attached below in 256-color PNG format, below 300kB each.
The first two are the top and bottom sides separately, and the third image is the two of them superimposed on top of each other so that the holes are matched and traces can be relatively easily followed.
 Hopefully many other people find this useful and not waste many frustrating hours or even days looking for this information like I did.

Here is the pin mapping in a plain text format, grouped for easier following (also attached below as a txt file):
