Not an issue but documentthe replacement of 74HC245 with SN74CBT3245A for INPUT pins
Reference Links :
*** Be sure you add a diode to drop the 5V input voltage to drop the voltag to 4.3V
Part Number : SN74CBT3245APW
You should swap out U28 , that will give you INPUT pins for J1 ( R0, G0, B0, R1, G1, B1 ) and J2 ( R0, G0 )
8 pins should be a good start.
You can test the input pins iusing the above links ( https://github.com/kittennbfive/5A-75B-tools/) or create a flow in Ice Studio (
