Need a motor controller

Sat Nov 18, 2017 2:49 am

Hi,

I'm looking for suggestions for a motor controller hat for a beginner, using a Pi 3 Model B.

I've been playing around getting motors working using what I have on hand, which is just a couple of TA7291P chips. They are ok, but painful to setup and use. Have set it up to drive two motors with integrated gears (part of a eBay kit I bought). Have also added in an IR sensor for obstacle avoidance (waiting for some ultrasonic sensors to arrive). Going great, but I know it would be easier and have more potential with a motor hat.

I've been looking at the Adafruit DC and Stepper Motor Hat (https://core-electronics.com.au/adafrui ... i-kit.html), but I'm a bit wary as I've never soldered before, and wouldn't want to wreck it before even using it. Is this a good option, or can someone recommend something better?

Thanks.

It depends on what voltage/current you motors require.

there are simple hats that have an L293D on them like this https://thepihut.com/products/motozero? ... o_s=gplauk

or if you need more current then you can used a board based on the L298N like this https://www.ebay.co.uk/itm/Dual-H-Bridg ... O4aqEA-sKA

no soldering required on the second option, you can connect the using female to female jumper wires https://www.ebay.co.uk/itm/40pcs-10cm-D ... uylcnJ5-RA

Thanks, I've ordered a couple of L298N's, they seem simple enough to work with.

In thinking it through, I will most likely put a sense hat on it to play around with, and from what I can tell most hats can't stack together, so the L298N's can sit to the sides or underneath.
