So I want to control the Arduino power using this RFP30N06LE MOSFET and that works as expected when hooked up to EZ-B D0. However, if the serial TX/RX is connected to the Arduino it get's power via the serial lines bypassing the D0 MOSFET. Any comments / ideas on controlling power and having Serial TX/RX lines connected?
Sorry I missed this thread. I had struggled with high side switching a few months ago here on this forum when I was trying to figure out how to turn off a Sabertooth motor controller. I can confirm that the circuit shown works as I've built a couple to let ezb switch off the positive side of the power feed to my motor controller. Here's the whole thread if you'd like to read through the struggle and see my circuit design. Turning off a Sabertooth
R2 needs to be reduced to at least 10 to work with an EZB v4. This was designed when I had a V3 ezb.
