Hi all!
I am new to PCB design. I am currently working on a project that interfaces 64x64 sensors with the Arduino. The sensors are connected to two 32:1 multiplexers for each row and column. And the output of these multiplexers goes into some other chip. This new chip communicates with the arduino via i2c protocol. I had already designed the PCB and placed the order. After receiving it, the PCB is not working. Neither the ICSP circuit nor USB-UART are working. Can you spare some time to help me find errors with the PCB board so that I can design it and place an order?
