Assembled and ready to test.
Input PCB has 96 inputs over 6 multiplexers with a nano on board. The last 2 digital pins are available on a header along with the 8 Bit Analogue signals as well.
The output PCB runs 3 chains of 2 DM13A to give 96 outputs using only 9 pins from an arduino.
Couple of issues I forgot the Enable signal for IC5&6 which I had to jumper and also the GND pins from each DM13A overlap the resistor pads, so those will have to solder in from the rear. Waiting on the caps to finish the board.
I’ll run some tests in the week and drop a video at some point.
Once these work they can go straight into my 737 overhead panel and I can get working again.
