DROK DC Motor Driver, L298 Dual H Bridge Motor Speed Controller DC 6.5V-27V 7A PWM Motor Regulator Board 12V 24V Electric Motor Control Module Industrial 160W with Optocoupler Isolation

The instructions clearly show the supply voltage for the logic circuit as 5V. This is wrong or misleading.If your control logic signals are 3.3V then the logic supply voltage must be 3.3V or it will not work. Several hours lost trying to debut that!Otherwise it seems good so far.

These are really nice motor controllers. Please be aware 5v input is NOT 5v input. It needs to match the high level logic voltage. If you are running a 3v3 microcontroller, supply 3v3 to this pin. If you supply 5v to that pin and run a 3v3 microcontroller, nothing will happen and the board will appear broken.

So the motherboard for my Apollo 835 Dual Swing Gate finally kicked the bucket after 20 years.While a replacement motherboard for my gate model was available for purchase, they were charging 500 bucks for it (and I was pretty sure I could do it for 50 bucks or less)The actuators that came with the dual swing gate kit operated at 12 volts with a fuse on the board limiting them to 3 amps. This made this dual L298 motor driver perfect in my quest to replace the motherboard.This dual L298 configuration has a similar pinout to just a single L298 board, except there are two of them. It still requires 12 volts to run the motor and a separate 5 volt to power the L298. The 5-volt pins for the L298 are connected so you only need a single pair of power cables.After writing some code for an Arduino Nano to mimic the original motherboard operation and rewiring each Swing gate actuator to work with the Nano and this motor driver. I was able to successfully replace the motherboard with about 20 dollars worth of new parts.A 3 Amp fuse is placed in series between the motor and the motor driver to prevent the motors from being damaged or if an object interferes when the gate is opening or closing. The motors don't have too much torque behind them, and the gates aren't heavy to move.While its current installation isn't pretty lol, it does not rain a lot where I am, and it also sits inside a weather-resistant metal box.I haven't had any issues for the past 3 mo since I installed this. (other than updating the programming on the Nano to fix some kinks)11/10 saved 470 bucks.
