2022-02-27 (Su) RemoteFinishLine New breakout board design

I considered making the next prototype board with only the LCD in mind and only providing voltage pins for everything else, but all the signals would run to the controller. I realized that approach was illogical and would result in a mad wire tangle. I sketched out the new circuit based on an Arduino Micro, but I didn't include the signal traces. I described the connections between the microcontroller and devices in a table off to the side. Keeping the IO in a chart lets me negotiate the pins before soldering anything. The LCD will attach to the top with right-angle headers to let the rest of the board hang off it. I will install a long header row at the bottom for my sensors and lights, but I won't need all the sockets. I'll be able to attach the distance sensor by plugging it directly, which will make it easy to mount for troubleshooting. The Bluetooth module should connect the same way. If this works, I may apply the principle to RangerRogue.
