Universal R/W multitool - AnyFlasher

Tested the first version of the board.

Found a few errors:
1. Missed route
2. Activation of the MUX without an address leads to a short circuit of the zero pin
3. The voltage drop on the Darlington array is too high

Conclusions: soldering the board to the end does not make sense, it is necessary to fix the PCB

The printed circuit boards have arrived. I have already started phased assembly and testing.
