Here is a list of changes made to the boards received from Sierra Circuits.
Board 1
- Individual channel 14 was missing C2. We placed the component on ourselves.
Board 2
- Individual channel 15 had 2 RBi's instead of an RBi and a CBi. We replaced the wrong RBi with the correct CBi.
Board 3
- Individual channels 11 and 15 had 2 RBi's instead of an RBi and a CBi. We replaced the wrong RBi with the correct CBi.
- The 100k resistor in the summer part of the voltage reference was actually a 442k resistor.
- The voltage regulator for AMPREF had the wrong pin out in our drawings. We rotated it so that VCC_VRef moved to where AMPREF was and a wire attaches from AMPREF to where VCC_VRef was.
- Changed the 35.7k resistor in the voltage reference to 130k in order to increase the current on each transistor leg.
