This is pretty well but are strange. Pretty sure they are HR8833. Though unlike authentic DRV8833 that use a separate VM and VCC pins, for power and logic, these use a single VCC pin with COMBINED power and logic that is internally regulated. While this simplifies wiring it is odd.With the J2 jumper pads disconnected, VCC on power, and the EEP connected to my ESP32's 3.3v, these work really well.

These work fine, I'm able to drive a small motor using a 5V power source and a 3.3V microcontroller without dropouts. Much better than, say, an L293.The documentation is wrong - it's the EEP pin the controls slEEP, not ULT. For the driver to function, EEP must be high (3.3V works), or J2 must be intact (use a meter to check, it's not obvious from looking). The faULT pin is so your controller can know if the driver has entered an overload/thermal shutdown.There is a bright red LED on the board which doesn't even shut off in sleep mode. I found this annoying, but was able to cut it without a problem.

In Tasmota set a GPIO to 'Relay' or 'PWM' and connect the board. No special library or special compilation needed. With Micro/Circuit Python set a pin as a standard 'Output' or 'PWM'.- Can be controlled with with 3.3v logic microprocessors like the ESP32.- Worked fine driving 5v 3W current to a 6v peristaltic pump (a DC motor).- PWM workes well too.Have not tried driving less than 5v and only used it for a few days.

Been using them forever to power N20 motors on 5V. Connect the H bridges in parallel to get 3A. They have thermal protection. Cheaper to get as part of a breakout board with all the passives than as individual chips.

I didn't like that the chip is not DRV8833 but rather HR8833. It does seem to behave the same as DRV8833. Although the chip has 16 pins, only 12 of those pins are broken out. The other four are not usually used but if you need to use them, this module won't work for that. I needed a motor controller to handle small 3 V motors. LM298 doesn't work with only 3 V. I tested this module at 3V and was able to control the speed through PWM in both forward and reverse. I doubt the 1.5 A claim but the motor I tested only used a fraction of that. For how long it will last, only time will tell. But it did satisfy my need to control these small 3V motors with PWM speed control both in forward and reverse. I gave one star off for not shipping what was pictured.

Works great for low voltage DC motors like the inescapable yellow TT gearmotors that are extremely common in entry-level robot kits. I have some L298N dc motor driver boards that couldn't operate at the 3-6V that the tt gearmotors require. I found these drivers and they work great with PWM inputs either directly from an Arduino, Raspberry Pi, Jetson Nano, or a PCA9685 driver board!

These are good drivers. however I do believe that 1.5A is the peak current rating, not the continuous rating. Also set the sleep pin high or the driver will not function.

This is great little driver for money. I strongly suggest to not go over 4V (1S LiPo) and run only 3V DC motors, otherwise, it will get hot and it will burn up.Works great when paired with Arduino Pro Mini 3.3V, NRF24L01, and 2xAA batteries. I'm using them for RC toys of all kinds.The only downside is you need 2 PWM pins per motor if you want to run forward and backward, but for around $1 a pop, it does not matter.
