I need to power my Raspberry Pi Zero W via the GPIO pins to save space. Since the BerryGPS-IMU is installed on the 40pin I/O header, I cannot directly connect power to the Pi’s GPIO pins. Can I connect power via pins 2 and 4 on P5 of the BerryGPS-IMU? I am using a regulated 5Vdc supply. Thank you for your advice. -Jim
