mCore - M1 & M2 port max current rating

#1

Hi there,

I would like to upgrade the motors on my mBot, and I was wondering what the maximum usable current draw is on the on-board motor ports. Based on the motor that comes with the mBot as standard, I am assuming it would be in the ±200mA range, but I am failing in finding definitive information about it. I am hoping someone might now the actual specification on this.

In addition to this, does the mCore controller have build-in over-current protection on its motor ports?

Hi Skynet

Here isthe link with the electronic schematic of mCore to you for reference.

Hi tech_support,

Thanks for the schematic. It helped a lot.

Good to know the mCore uses a TB6612 driver on the motors which can handle 1.2A per channel.

It seems like it will be able to handle the Tamiya 70168 Double Gearbox Kit. :heart_eyes: As long as it does not stall for too long :stuck_out_tongue_closed_eyes:
