How to wire up 2 Double BTS7960 43A H-bridge High-power Motor Drivers

Hi Folks,

I am moving from an ESC setup for a skid steer boat to trolling motors (from brushless to brushed motors).

So I now have a pixhawk 2.4.1 and 2 of these

But I cannot find any useful info on how to wire them to the pixhawk.

This page tells me it’s possible but is useless for which pins are used for what.

So for each motor I have the 3 pins in the back of the Pixhawk (-) (+) and (S) on outputs 1 and 3. and I have set the SERV01_FUNCTION and SERV03_FUNCTION to Steering Left and Steering Right and MOT_PWM_TYPE = 3 (BrushedWithRelay).

But I do not know how those pins should be wired to the 8 pins on the bridge drivers.

Can anyone point me in the right direction please?


Never mind folks. I’m giving up, following advice in other posts here and ordering 2 of these

this driver can only be connected with arduino. flash the arduino and it works great. see photo below
