i have a gw370 motor connected to a TB6612FNG motor driver, which is powered by a 12V battery. an arduino uno is connected via the 5V pin to the TB6612FNG motor driver to power the logic and the uno is powered by some separate AA batteries.
it doesn't work at all so wondering if i got the wrong parts together. the gw370 has a stall current of 1.3A and a rated current of 0.5 A. the TB6612FNG has an output of 1.2A and 3A max. as the motor is only being used for a light activity i figured is okay i measured it running too without the TB6612FNG and it was 0.4-5A. the TB6612FNG has a VM = 15V max.
the battery i thought would just be 12V as that is what it was sold as but i read on the side has a standby use 13.5 - 13.8V and a cycle use of 14.4-15V so i was wondering if this was too close to the upper limit of the motor driver. although i measured the battery by itself with a multimeter and it was 12.5V.
it's also possible i had the wrong wiring or code but i think less likely as i used several pre-existng examples although often i had to remove the code for the 2nd motor as i only have one and most examples had two. also possible is i didn't solder the TB6612FNG yet i just pushed the pins into a breadboard and connected the battery and uno through that, not sure if that's technically how you're supposed to do it.
so in summary i was basically wondering if i have the right parts and if i have ruined the motor driver (TB6612FNG)?
