## Description

Compact dual H-bridge for controlling two DC motors or a 4-wire stepper motor, allows direction and speed adjustment via PWM, operates at 2-10V and accepts 1.8-7V signal, delivers up to 2.5A per channel with high efficiency without a heatsink, includes thermal protection with hysteresis and almost zero standby consumption, compatible with Arduino and other development boards.
The Mini DC Motor Driver Module, with PWM, with dual channel 2.5A, compatible with Arduino and other development boards, allows the control of DC motors up to 10VDC. The module is a dual H-Bridge, which can control two DC motors or a 4-wire, 2-phase stepper motor, with the ability to adjust the direction and speed of rotation. The module operates on a supply voltage range between 2V and 10V and is optimized to reduce power consumption and the risk of overheating, without requiring a heat sink.
It uses the MX1919H IC, capable of supporting 2.5A current per channel, being a more reliable alternative to the classic L298N.
The module has a thermal protection circuit with hysteresis effect, providing safety in the event of motor stalling.
The module has a small size, low weight and 0 standby power consumption, without requiring standby current.
Technical specifications:
Module supply voltage: 2V - 10VDC
Signal input voltage: 1.8V - 7VDC
IC: MX1919H
Operational current per channel: 2.5A
Standby current: < 0.1µA
Mounting hole diameter: 2 mm
Dimensions: 33 × 31 × 5mm
Use:
Observe the polarity of the supply voltage to avoid damaging the circuit.
Avoid short circuits to ground and motor blocking. Although the module is thermally protected, at voltages close to or greater than 10V and peak currents above 2.5A, there is a risk of burning the circuit.
Connecting the wrong polarity can cause irreparable damage.
In cases of high voltage and high peak current, motor stalling can damage the chip, even with active thermal protection.
