I was looking at the Ublox NEO-M8N GPS with compass (ROM) and wondered what the input voltage range was?
I was also wondering if it outputs a 3.3V SCL/SDA I2C signal for the Compass as I would like to connect this to an SP Racing F3 Acro board.
Hi
Power the unit at 5 volt, the magnetometer (compass) inside has it’s own 3.3v regulator and you can connect the two SCL/SDA wires directly to the pads on the FC.
