    Project: 40 & 28 PIN PIC DEVELOPMENT BOARD

    Hi there, These capacitors are filter ones and need to be placed in various spots on the board, near voltage inputs, outputs, IC power pins and other place, so they filter the noise on the Vcc line across the board, so that's why they are many and connected on main voltage. 1n5422 diodes...
