Please note that the picture showing the nodemcu sitting on the board is wrong. The nodemcu should sit the other way round, with the antena as printed on the board. Then the pins labels on the nodemcu and the board match. Bye the way, I'd love to have a schematics of the board, showing the connections between the l293DD and the nodemcu Jacques Benaroche
Todo correcto.
This is a nice motor controller that fists the Geekcreit size ESP-12. (back says 'ESP12E Notor shield'). Helpful pin-out information is here https://cdn.hackaday.io/files/8856378895104/user-mannual-for-esp-12e-motor-shield.pdf
Спасибо
Got this with the nodemcu do it car esp826 and works great. I use it like a variable power supply to control various arrays of l.e.d's with the doit car app.
Once you gain experience with NodeMCU and LUA you can have this motor driver working in less an hour. It has a problem, well, maybe it not a problem if is used with normal motors, i plugged a 9v led (SKU060051) for having a dimmable light, but the driver can't handle 1.2A as description (and official page) says, the led consumes 400mA, but when connected to the driver at 100% the voltage falls to 7.9V and the led has not its full bright. Putting both outputs in parallel dont make significant difference.
I bought this expansion board with the NodeMCU and was able to get it working with no problems using NodeMCU LUA. To quickly test that the board is able to drive a motor, I plugged in the motor to screw terminals A-/A+ and then ran the following LUA commands: > gpio.mode(1, gpio.OUTPUT) > gpio.write(1, gpio.HIGH) The motor started spinning right away!
fast delivery very good product
