Problem with Strong Gripper on Me Motor Driver V2.0

#1

Hi there,

I try to use the Strong Gripper on a additional Me Motor Driver V2.0.
The Driver is connected to Port_1, so I use the following code to initialize:
MeDCMotor motor1(PORT_1);

After that something like
motor1.run(100); or motor1.stop(); should work, but it doesn’t.

when i use the Gripper on M1 it works.
On Port_1 or Port_2 it doesn’t work.

So I took a look at the driver and I saw this:

Is it wanted, that the pins at this 4 marked areas where shortened?
The driver on the pictures showed on the makeblock-website doesn’t look like this.

So, do I have a problem with my code, or is there a problem with the driver?

Greetings, Daniel

Hi @dna,

Sorry for the error. Actually, it’s a little complicated to explain this.

As you can see in the picture below, there should be no problem with the pins which green arrow point. But the red two pins is wrong indeed.

Actually, on the PCB board, the pins of TB6612 is shorted circuit like this, so if the factory solder even number pins together, there should be no problem.

But you can see that there are 5 pins at the left of the error two pins, so it should be wrong.

The solution – If you can solder, you can just separate the two pins. I think it could work.

Hi,

I own a suitable soldering-station (i think :wink: ).
But the pins were to close to the Alpha220L-Chip.
So I can’t get it to unsolder the pins. I can’t get between it.
