USB-C GPS/GNSS module with an integrated USB-to-serial converter, 99 channels, 10 Hz position updates, and NMEA output. Plug-and-play with computers and embedded Linux boards; onboard LEDs indicate fix status.
USB-C GPS/GNSS module with an integrated USB-to-serial converter, 99 channels, 10 Hz position updates, and NMEA output. Plug-and-play with computers and embedded Linux boards; onboard LEDs indicate fix status.
Power input for the GPS breakout, source states connect to a clean 3-5VDC supply.
Power and signal ground, connect to power supply and microcontroller ground.
Optional RTC battery-backup input for the GPS real time clock battery backup.
Enable pin pulled high with 10K; pulling to ground turns off the GPS module.
Output from the onboard 3.3V regulator, source states it can provide at least 100mA.
Serial data transmitted from the GPS module to a microcontroller or computer; default 9600 baud.
Serial data input to the GPS; source states 3.3V or 5V logic is accepted via level shifter, default 9600 baud.
Fix-status output shared with the red LED; pulses once per second with no fix, mostly low with a brief pulse every 15 seconds when fixed.
Pulse-per-second output on V3 modules; mostly logic low and pulses high once per second for 50-100ms.
