I was planning on getting the Makerfabs Dual H-Bridge DC motor controller, product code RB-MKf-04, to help with controlling 2 DC motors along with an Arduino Uno. My question is how do I power the Arduino separate from powering the DC motors when using the (RB-MKf-04) DC motor shield?
Hi,
From the schematic the manufacture provide, the DC Motors power supply (through the VIN 5-22V screw terminal) seems to be isolated from the Vin pin on the Arduino Board.
Powering the Arduino board through the power jack/Vin pin will supply power to the Arduino board and internal logic of the shield and won’t power the motors.
The motors are powered only through the screw terminal and driven through the two H-Bridges with the IRF3205S MOSFETs
Hope this answers your question,
