Hi, the dual mc33926 motor driver carrier provides the EN pin but the dual shield does not. I would like to put the (a*star) arduino I’m using to sleep and also the shield. I see 2 options:
- Find out how to access the EN pin on the circuit - I will have to look at the PCB and maybe “invade” it.
- Disconnect the VDD to (Arduino) 5V connection and provide VDD via an Arduino GPIO pin.
What do you think about the 2 options? On the last one do you think it is ok to have motor vin connected to 2s lipo battery while vdd is pulled low? I read the datasheet of the mc33926 and it draws 20mA in normal operation and 40 mA is typically ok for an arduino to provide via a GPIO.
