Hardware Overview

Communication Ports
The NEO-M8P-2 in unique in that it has four communication ports which are all active simultaneously. You can
read NMEA data over I2C while you send configuration commands over the UART and vice/versa. The only limit is
that the SPI pins are mapped onto the I2C and UART pins so it's either SPI or I2C+UART. The USB port is
available at all times.
