Ask you about the specific connection method, it has the wiring diagram,thank you very much!!!
Probe. You only need ground, tx, and rx. If you try 9 different variations, 1 of them will be correct.
Pin3 looks like GND to me, now you only need to find the other two
Hope you don't try connecting your TTL adapter to the SPI chip.
Some times a wonder if ppl even read before they jump and post. You will need the NT to do that job.
