HGLRC M100 MINI GPS Module, u-blox M10, 15x15mm, for 2-7 Inch Drones

The HGLRC M100 MINI packs a full 10th-generation u-blox GNSS chip into a genuinely tiny 15x15x5.2mm body, small enough to fit into the tighter electronics bays found on 2 to 7 inch FPV drones where a larger GPS module simply wouldn't have room. Despite the compact size, it supports GPS L1, GLONASS L1, BDS B1, Galileo E1, SBAS L1 and QZSS L1 signals across 72 receiver channels, genuinely broad multi-constellation coverage rather than a cut-down feature set to match the small footprint.

A ceramic antenna paired with an externally extended PCB section helps the module pull in satellite signal despite its tiny size, since a smaller antenna generally means reduced sensitivity unless compensated for with careful RF design. Output rate reaches 10Hz with a baud rate of 115200bps, fast enough for responsive GPS-assisted flight modes, and horizontal accuracy is rated at 2.0m outdoors in 2D mode, with speed accuracy of 0.05m/s.

Sensitivity figures are strong for a module this small: -166dBm tracking sensitivity and -160dBm acquisition sensitivity, meaning it can find and hold a GPS lock in weaker-signal conditions than a less sensitive module would manage. Onboard LEDs show power status and PPS (pulse-per-second) timing lock, giving a quick visual check that the module is both powered and actually tracking satellites without needing to plug into a ground station to check.

The module runs on 3.3V to 5V input, operates from -40C to 85C, and the package includes the GPS module, a 12x20mm heat shrink tube for the connector joint, an HGLRC sticker, a printed manual, and an SH1.0 4-pin connecting cable. Builders working on compact 2 to 7 inch freestyle or racing quads who need genuine multi-constellation GPS without the bulk of a larger module will find the M100 MINI's small footprint and broad satellite support a strong match for tight builds.
