Involvement:General (knows how to use it) - Ownership:more than 1 month
Received device was as is in the photos(same colors and so on). Heat sink is really helpful(because I am driving two DC motors at 5V and motors has more than 2amp stall current ), so no problem at all. After intensive usage heat sink becomes warm/hot. Device has five red leds: one for power and others for IN1 IN2 IN3 IN4 high signals indication.
Bad that I could not find any documentation. Problem is with yellow "in" connections line. I have just guessed and used only IN1 IN2 = motor1, IN3 IN4 motor 2. And everything worked fine. Not sure why there is GND and +5V. I have skipped EN pins (No low or high signal, this is quite strange)
Please share some documentation
This is lower price for sure. Thinking about second :)
