Remove the FUSB302 and add two 5.1k ohm resistos to R1 and R2. Slide the board into the 3D printed part and secure with some glue if needed. Add two wires to DFU and 3.3V (break out the DFU-Button so you can boot into DFU-mode while the case is closed).

#### 4 - Wiring 1
Wire the dials from the old ADC to the ADC-inputs of the OtterPill (PA1-PA7, PB0), connect the exposed pad from R3 to 3.3V from the OtterPill and connect 5V to the center of L1. Additionally one can add 10nF capacitors to the ADC inputs to stabilize the readings.
