Dual VNH5019 Motor Driver Shield

I’m looking to use this driver shield on an Uno R3 to control 2 different actuators with a max current draw of 9A and a voltage of 12V. All they need to do is extend and retract fully, no speed control (https://www.progressiveautomations.ca/products/tubular-high-speed-linear-actuator). I’m wondering if I can also use it to control a relay module (something like this https://www.amazon.com/HiLetgo-Channel-optocoupler-Support-Trigger/dp/B00LW15A4W/ref=sr_1_3?dchild=1&keywords=Arduino+Relay+Module&qid=1606095204&sr=8-3) or is this too much for a single Arduino? I’m pretty new to this sort of thing so any help is welcome, thanks!

I moved your post to the “Motor controllers/drivers and motors” since it seemed more appropriate.

You should be able to control the VNH5019 shield as well as a relay module from a single Arduino as long as you control the relay from a GPIO pin that does not conflict with the shield. You can see which Arduino pins are used for each function from this diagram on the VNH5019 shield’s product page:


Thank you so much, I’m very new to this sort of thing so I wasn’t sure of the limitations.
