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.

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.

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!

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.
