that is, you want to tell me that it still doesn't work ???? but in substance what is it that you miss? anyway many compliments. You don't know how much it bugges me to buy all the engines and not to be able to take advantage of those supplied by the Wors

I have bought a flymo1200 for 50 bucks.

The robot was hit by a car and i repaired the gearmotor, but the mainboard is broken. The motors in this one are brushless, so I bought the same drivers like you.

I have already tested it: Driver are set to Romeo, connected only dir and pwm, motor fault pins set to _PULLUP.


What i realized later was, that the driver has 4k7 pullup to 5v on the dir pin. Is that a problem for the due?

And i need to check the standby current of my other mower. This one has 100mA only with the 2 motordrivers.

I am also interested in this thread. I have a broken Worx Landroid WR105SI (water damage)
The main PCB is completely dead, but the motors and sensors still look ok. Is there an easy way to test the motors using a bench power supply?

@Longri did you ever finish the driver PCB's? They look promising. I was thinking about creating some custom PCB based on the original chip used: MC33035 (DW)
But I am not looking to reinvent the wheel.

I haven't got any further yet, I'm just a little short of time!
But I hope that I can get further in the winter time.
At the moment I am building myself a laboratory board that I can take with me to my workshop without always taking the whole Mover with me.

I follow you with devotion. I organize myself, so we can collaborate. I want to revive my Works WG795E

Just to let you know, I managed to get the motor working this evening! I am using a similar driving board like yours.
I will post some details later this week, including pinouts etc.
