Description of HiLetgo Controller Stepper H Bridge Mega2560

L298N as main driver chip makes strong driving ability/small heating/strong anti-interference/low calorific value. Use large-capacity filter capacitors and diode with freewheeling protection function, increasing reliability. Dual-channel H-bridge driver working mode creates higher working efficiency. To avoid damage the voltage stabilizing chip, please use an external 5V logic supply when using more than 12V driving voltage. Large capacity filter capacitance, afterflow protection diode, more stable and reliable.

Expected for industrial electronics

All the devices on this board appeared to be placed and soldered in an automated process, so they're pretty solid. On the other hand, the motor driver and heatsink combo is what I expected from this price point: terrible. On 3/4 of these boards I could put the panda between the motor driver and its heatsink, which of course means it does next to nothing. On the 4th the driver leaned until it touched the edge of the heatsink but still not perfect. If you run *every* board I received at full…

Pros
  • Dual channel H-bridge driver mode offers better performance
Cons
  • Slightly torn

Beware of poor heatsink assembly - The gap between heatsink and thermal pad

These are excellent small modules for the price. Easily control the speed and direction of two DC motors or parallel outputs for more power. The only issue I had was the poor quality control of the heatsink attachment. There was a significant gap between the heatsink and the thermal insert. There's also no thermal paste or thermal pad between the heatsink and the tongue. This caused the part to overheat at only 30% of the rated load. Luckily, the solution was to simply tighten the screw until…

Pros
  • L298N as the main driver chip ensures high controllability/low heat/strong anti-interference/low calorific value
Cons
  • fragile
