DRV8835 FOR RASPBERRY PI B+ 其他数据使用手册 - Pololu Robotics & Electronics

Although the DRV8835 itself works with a minimum motor supply voltage of 0 V, this

board’s reverse-protection circuit limits the minimum to 1.5 V. If a lower motor supply

Motor supply voltage: 1.5 V to 11 V

Logic supply voltage 2 V to 7 V

Output current: 1.2 A continuous (1.5 A peak) per motor

Motor outputs can be paralleled to deliver 2.4 A continuous (3 A peak) to a single

motor

PWM operation up to 250 kHz (ultrasonic frequencies allow for quieter motor

operation)

Two possible interface modes: PHASE/ENABLE (default – one pin for direction,

another for speed) or IN/IN (outputs mostly mirror inputs)

Board can optionally power the Raspberry Pi base directly through add-on regulator

Assembly with included hardware

Before the motor driver board can be plugged into your Raspberry Pi, female headers must be

soldered into the appropriate holes. The kit ships with two 17-pin 0.1″ female headers that should

be mounted to the bottom of the board (the side with surface-mount components). Once the kit is

assembled, it should be plugged into the leftmost position on the Model B+’s GPIO header, leaving

six pins exposed on the right, as shown in the picture below.
