Attached are two pictures of my first pcb board· I've designed and had built at pcbexpress.
The·first ·picture is of the first version of the pcb. It has
Power supply. This was removed when I realized that I could just grab power from the spin studio board.
6 op amps but only 2 are connected. There are 2 blank holes for 2 more opamps. The blue above are pots to·· adjust· gain of the opamps
1 adc 8038.
The·right picture·has ·4 chips and a lm34.
left·············· ·quad op amp
second······ ··· adc0838
third············· lm34
fourth··········· adc0838
small at top··· dual op amp
The orange and yellow wires are for the keypad.
The jumpers on the card are connections that were missed in the prototype and will be connected in the next run.
