Equipped with enhanced SAM-M10Q chip-antenna module
Receives signals from up to four GNSS constellations
Offers 1.5m horizontal position accuracy and 18 Hz update rate
Features a rechargeable 3V/1mAh battery for backup power
Integrates seamlessly into the Qwiic system with no soldering required
The SparkFun GPS Breakout - Chip Antenna, SAM-M10Q (Qwiic) is equipped with the SAM-M10Q chip-antenna module from u-blox. This module is the successor to the M8Q module found on the previous version of the SparkFun GPS Breakout, and it offers enhanced features that significantly reduce power consumption while simultaneously improving performance and accuracy. The SAM-M10Q is capable of receiving signals from up to four GNSS constellations simultaneously, which enhances time-to-fix and positional accuracy, even in locations with limited sky visibility.
The SAM-M10Q module comes with an integrated chip antenna and is compatible with the L1 band across all five GNSS constellations, namely GPS L1 C/A, QZSS L1 C/A L1S, GLONASS L1OF, BeiDou B1C, and Galileo E1B/C. It boasts a horizontal position accuracy of 1.5m and a maximum update rate of 18 Hz when transmitting with a single GNSS constellation, or 5 Hz when transmitting with four GNSS constellations. The module also features a cold start time to fix of 23 seconds. The board is equipped with a rechargeable 3V/1mAh battery that can provide backup power for up to four hours, ensuring a hot start of just one second.
This board is designed to integrate seamlessly into the Qwiic system, eliminating the need for soldering when connecting it to the rest of the I2C system. However, for users who prefer a soldered connection or prototyping on a breadboard, the board also breaks out 0.1"-spaced pins.
The GPS products based on u-blox can be configured using the Windows program called u-center2. This program allows for the customization of a wide range of settings for the SAM-M10Q, including baud rates, update rates, geofencing, spoofing detection, external interrupts, SBAS/D-GPS, and more. There is also an Arduino library available for configuring the SAM-M10Q.
It is strongly recommended to use the u-center2 program with this board, rather than the original u-center.

Products must be returned in unused, unmodified condition (e.g., no scratches, alterations, missing parts, or signs of installation/use) and in their original packaging, suitable for resale.
Shipping fees are non-refundable. Return shipping costs are the responsibility of the customer, except in cases of a product confirmed defective through RoboItchi's troubleshooting process or of a verified shipping error by RoboItchi.
Refunds are processed within 7 days after receipt and inspection of the returned item.
A ¥10,000 cleaning fee may apply to domestic robots returned in used or unclean condition.
A 20% restocking fee may apply to large-quantity returns of items ordered specifically for the customer from the manufacturer or not part of RoboItchi's standard inventory.
Return Exceptions
The following products are not eligible for return or refund under this policy:
Used, damaged, or modified products — Items that show signs of use, wear, or alteration, making them unsuitable for resale.
Consumables — Use and wear-and-tear components, altered or depleted through use (e.g., batteries, belts, brushes, gears, filament, tires, disposable bags, lubricants, greases, waxes, etc.). Not eligible for return once opened or used.
Perishables — Goods liable to deteriorate or expire rapidly. Not eligible for return.
Sealed goods (health or hygiene) — Items sealed for health-protection or hygiene reasons (e.g., masks, gloves, odor-absorbing products). Not eligible for return once unsealed.
Build-it-yourself products and items requiring customer assembly — Including robots & kits, robot parts, and other products requiring assembly or soldering. Not eligible for return once assembled, soldered, or installed.
Digital Goods, Software, and Apps — Final sale only, due to licensing restrictions.
