  • Great controller for two motors

    posted by ACOrtega

    The price is unbeatable and it is a tiny board, ideal for small appliances like a robot that have no more than two motors. The construction is good, worked fine at the first test.
    I found an excellent site with examples and some documentation:http://www.bajdi.com/l9110-h-bridge-module/On the Internet you can find other references as well. Please pay attention that the board in the picture is slightly different, having different pin names and order. Nevertheless it is easy to make the correspondence with the two boards and the functionality is the same
    Great price, simple and easy to use.
  • Perfect for me

    - Comes in a perfect package, protected and looks nice;- I have already test two different firmwares, sprinter and repetier. Works grea
    - The only problem is the same of any other product coming to Brasil... the time to arrive is so long.- Maybe DX can sell another models with everything in the same board.
    DX can sell more parts for this printers, NEMA17 motors, linear guides and bearings.This is a new market, every time we got more news about 3D printing. Maybe I am wrong, but the future for this product is big.We dont need machines of thousand dollars, if we can build by our own, for a low price, we will do that! We can do everything we need!
  • Works like the charm!

    - It's cheap but looks solid. - Works as expected.- So far quiet (without annoying buzzing).- Screw terminals for wires.
    The adjustment pots are not described on the PCB so little guessing is needed.The coil is not fixed to the board - would be nice to glue it to the PCB.There is no input polarity protection diode so do not swap power cables!Overall quite useful piece of product.
    Definitively worth the money, so buy it if you need one.
  • Great circuit for controlling two DC-motors or stepper motor

    posted by SamiVakkuri

    Great circuit for controlling two DC-motors (or stepper motor). I use it with 12V battery and Arduino Mega to control ~20W motor and it works properly.
    Here example about working: A1: A2: Motor state:| 0 | 0 | Freerun| 1 | 0 | Clockwise| 0 | 1 | Counter-Clockwise| 1 | 1 | Brake (motor short circuit)-You can control speed of motor with PWM-signal
    Great and cheap for anyting with quite powerful DC-motors.
  • very good reliable driver

    - easy to use- easy to solder- delivers 1.4A to led- 1 mode perfect for simple designs and retrofitting in old lights.
    easy to solder. small diameter fits in many old lights. perfect for updating old lights. straightforward use. no problems with soldering. I used it for an xml led and it delivers 1.4Amps to the led. The use was with no problems and the driver works without geting too hot.
    nice driver. veru useful. easy to use. I expect a 1-mode 2.0A version...
