I’m not sure a part is going to be possible. This appears to be very poorly documented. The various images are blurry and the connections unclear. I have not been able to find any clear indication of what the connectors are.
there is what claims to be a schematic and pcb layout, but it doesn’t appear to bear any resemblance to this board. Without better information I expect this isn’t worth attempting.
While at this point I am sorry I made this, here is a part which may do what you want. The pin labels are likely wrong, there is no information on the debug ports that I can find (including pin layout) so they are there but probably not correct. Pcb view is suppressed as not useful.
