Description

Use this engine driver to turn 2 Motors continuous or a unipolar or bipolar stepper motor with up to 1.2 by phase thanks to the DRV8833. This driver engine was an alternative to the TB6612. Like the latter, this circuit has 2-H bridge complete, but he better ets with the low voltages (it works with 2, 7V to 10 engines, 9V) and it has a built-in current limiter. It has been set to 1, which will allow you to fly 2A to the max with the circuit. You can of course change or remove this limitation.

The DRV8833 circuit was welded on a map of breakout, with protection diode of polarity on the motor power supply part. Each circuit has two full H-bridge, which means that you can control two motors continuous or a stepper motor. You just make sure that they consume no more than 1? 2A, which was the limit circuit. It can withstand a 2A peak for an instant and by changing the current limiter. We love particuliermeent this circuit because it has protection diode in order to avoid any return current inductive. And the current limit will protect the circuit against any over-current.

Each ets H-bridge led through two entrances and can be applied voltage PWM to vary speed of rotation. Feed the logical part ets the me for the motor part, but control can be made to part 2, 7V. It is therefore possible to supply ' together in 9V and work in logic 3, 3V or 5V.

The card is sold assembled and tested with a jack plug not welded.
