Good day! I am an electronics designer myself. I will look for such a board for measurements, but it is discontinued and is no longer for sale. This makes searching difficult. I found out what the components are, it remains to find out their denomination, more precisely, under No. 1 and No. 2, I have already replaced the rest of the elements. No. 1 and No. 2 are resistors, I assume that No. 1 is within 22R, and No. 2 is denominated from 4.7k to 22k.
I found out that this is an SPI data exchange circuit with a FLASH chip. It would be enough for me to assign the output of the processor (the names of the circuits).
