The DRV8833 is a dual H-bridge motor driver IC on a small breakout board, built to give bidirectional control of two brushed DC motors, or alternatively a single bipolar stepper motor, from one compact module. It operates across a 2.7V to 10.8V supply range, suiting most small robot battery packs, and each channel handles 1.2A continuously with a 2A peak tolerance for brief current surges, such as a motor starting under load.
For a single motor that draws more current than one channel can comfortably supply, the two outputs can be paralleled together to deliver up to 2.4A continuous with a 4A peak, effectively turning the two-channel driver into a single higher-current channel when only one motor needs to be driven.
Inputs are compatible with both 3V and 5V logic levels, so the module works directly with 3.3V microcontrollers such as an ESP32 as well as 5V boards like an Arduino Uno, without needing a level shifter in between. Reverse-voltage protection guards against a wiring mistake on the power input, and under-voltage lockout combined with over-current and over-temperature protection helps prevent damage to the chip during a stall or short circuit.
Current limiting is possible through external sense resistors, sold separately, for projects that need tighter control over motor current beyond the driver's built-in protection thresholds. The board itself is small, at 16 x 18 x 8mm and 5g.
Builders of small wheeled robots, robot arms or other dual-motor projects who want a compact, well-protected driver that works with either 3.3V or 5V logic will find the DRV8833 a convenient and dependable choice.
