55_Finalizing PCB Dimensions in Ultiboard
After splitting up the electrical schematics I was able to verify that the processing layout could fit on a 2x3 inch board (Figure 1). While the motor control layout is not finished yet, it looks like it will also fit onto a 2x3 inch board which can be stacked above the processing PCB (Figure 2).
