Details

The Sub250 SUB-M10 is a compact GPS module built for reliable multi-constellation L1 positioning in space-limited builds.

Joint positioning across GPS, BDS, GALILEO, QZSS, and SBAS helps maintain stable lock and consistent accuracy in open-air use.

Powered by the u-blox M10 series chip (M10050) for responsive acquisition and dependable navigation performance.

Onboard LEDs make it easy to check power and GPS working status at a glance during setup and flight.

A 15×15×5.2 mm footprint and 2.6 g weight keep installations clean without adding noticeable mass.

Wiring is straightforward with UART: connect GND and +5V, then cross TX/RX between the GPS and flight controller.
