In an earlier post, A high density Automotive control design using the Microchip PIC32MX MCU was described. That design was a great success. However, as with all things new it was found to be in need of more I/O. The circuit board was revised to double all of the digital and analog peripheral I/O while retaining the same overall PCB outline of 5″x7″. it was also kept to just 2 layers and components on only one side, again with the help of the peripheral circuitry simplicity afforded by the Microchip PIC32MX360F512L MCU.
While it is a bit more dense that the previous revision, it still fits without too much crowding on the 5″ x 7″ 2 layer PCB.
