Before the Big Trak circuit can be used by the Raspberry Pi it is necessary to remove IC2 and IC3 from the board. These are tricky to remove but so far the best approach is to use a heat gun to remove them. If you don't wan't to remove the IC's then the tracks could always be cut. | Before the Big Trak circuit can be used by the Raspberry Pi it is necessary to remove IC2 and IC3 from the board.
