Voltage Divider
Two resistors used to scale a higher analogue voltage down before it reaches a microcontroller ADC input.
Two resistors used to scale a higher analogue voltage down before it reaches a microcontroller ADC input.
Measured positive input on the 2-pin voltage input header/screw-terminal side of the divider.
Measured negative input and ground reference for the divider.
Divided analog voltage output to the microcontroller ADC. DFRobot product/wiki describe the module as an analog interface that divides the measured voltage by 5.
Ground/reference pin on the PH2.0 Gravity analog connector.
