Geared DC Motor with Magnetic Encoder Outputs - 7 VDC 1:20 Ratio

The first step in a robotics project is to get a motor spinning. Once you've done that, you quickly learn that not all motors go the same speed, even if they are the same part number! There are always variations that relate to voltage, environment, and manufacturing changes.

Red wire / M+
Motor drive lead. Adafruit says to apply 7 V DC nominal to the red (M+) and green (M-) wires; these connect to a motor driver and can be PWM driven through an H-bridge.

Green wire / M-
Motor drive return lead. Adafruit identifies the green wire as M- for the motor driver/H-bridge connection.

Black wire / GND
Encoder electronics ground. Adafruit says to connect the black wire to the microcontroller ground pin.
Type · groundVoltage · 0 V reference for encoder electronics
Blue wire / VCC
Encoder electronics supply. Adafruit says to connect the blue wire to 3-5 VDC.
Type · powerVoltage · 3-5 VDC, source-backed by Adafruit product page
White wire / Hall output
Hall-effect encoder output. Adafruit says the hall effect outputs are on the white and yellow wires.
