DFRobot DFR0051 Gravity Analog Voltage Divider V2
A DFRobot Gravity analog voltage-divider module that scales a 0.0245–25 V DC input by five for measurement through a microcontroller analog input.
Pinout
- VIN+DFR0051 official schematic J1/Header 2 input side
Measured positive input on the 2-pin voltage input header/screw-terminal side of the divider.
Type · PowerVoltage · 0.0245V to 25V DC measured input - VIN-GNDDFR0051 official schematic ground node / J1/Header 2 input side
Measured negative input and ground reference for the divider.
Type · GroundVoltage · 0V reference for measured input - SignalDFR0051 official schematic Signal net on J2 PH2.0 connector
