Here the next boards came to us and we have even soldered them. And running to the front I will say that we went through the checklist and everything works as expected. in fact, there were a couple of replacements, there was no pin on the NFC processor, and a defective frequency generator was caught. But after identifying defective parts and replacing them, everything started up easily.
And now we are doing the last piece of software that we could not complete earlier - this is the creation of a driver for communication between halves using the USB protocol, type C.
And here is our own checklist of 173 points to guarantee the working capacity of almost 600 components on each half:
