10K POT
Keep noisy signals away from ADC circuit
J21: 1-2 V1P8_ADC_VREF (Default)
2-3 J26 connector input
J22: 1-2 V1P8_ADC_VREF (Default)
2-3 J26 connector input
J24 1 = 10K POT
J24 2 = ADC_DN0
J24 3 = J26-3 Connector
J25 1 = GROUND
J25 2 = ADC_DP0
J25 3 = J26-5 Connector
To select POT, wire jumper:
J24-1 to J25-2
J24-2 to J25-1
