sx1276

I am using a LoRa SX1276 in a low-power project, powered by an 18650. When I use a P-channel MOSFET to cut the VCC of the SX1276, it draws power from the SPI pins. I am using an Arduino Nano and plan on using an Arduino Pro mini in the final device, the Nano normally draws 2.7mA in sleep, and...
