Excellent H-bridge controller
This unit is well engineered. They made an effort to use the PCB as a heat spreader. It used advanced manufacturing, and rework should not en done lightly. The ratings are mostly conservative. The unit val take huge peak loads. The power connection goes through a relatively small connection path, possibly intended as a fuse. The capacitors help with switching current and reduces power supply glitches. The controller can get confused and need a reset. This suggests there are some nice safety features - TBD. We used a thermal pad to the case to dump heat.

Works as expected!
Easy to use. Connected to a Teensy 4.1 and is driving a linear actuator. Only tested ro 3 Amps peak but no heat at that level. Best value i coyld find for a controllable DC motor driver over 10A.

Work very nicely with Arduino
This board has nice on/off button for testing and built with TI chip. PWM input from external source works well and drive the motor with 20Amp rating. Arduino using analogOut function command scale to 0(0%) to 255 (100%) works very good too.
