Product Description
This compact breakout board makes it easy to use Allegro’s A4990 dual motor driver, which can control two bidirectional DC motors over a wide operating voltage range of 6 V to 32 V. It is capable of delivering a continuous 0.7 A to each motor channel, and onboard sense resistors enable the A4990 to limit the peak motor current to about 0.9 A per channel. The driver also features protection against reverse-voltage, under-voltage, over-voltage, over-current, and over-temperature.
- Dual-H-bridge motor driver: can drive two DC motors or one bipolar stepper motor
- Operating voltage: 6 V to 32 V
- Output current: 0.7 A continuous per motor
- Current control limits peak current to 0.9 A per motor
- Inputs are 3V- and 5V-compatible
- Robust:
- Reverse-voltage protection circuit
- Can survive input voltages up to 40 V2
- Under-voltage and over-voltage protection
- Over-temperature protection
- Short-to-supply, short-to-ground, and shorted-load protection on the motor outputs
Included hardware
Two 1×8-pin breakaway 0.1″ male headers are included with the A4990 motor driver carrier, which can be soldered in to use the driver with perfboards, breadboards, or 0.1″ female connectors. (The headers might ship as a single 1×16 piece that can be broken in half.) When used with these header pins, the board can be oriented with the parts visible, as shown in the right picture above, or with the silkscreen visible, by soldering the headers in from the opposite side. You can also solder your motor leads and other connections directly to the board.
