GPS Receiver U-blox M10 Bluetooth, Compatible with Michibiki, Turns Smartphones/Tablets into Car Navigation Systems [Large Antenna Version] [Large Antenna Version] This is a DIY GNSS/GPS receiver (Bluetooth) using the latest U-blox M10 module. It was created to turn Android tablets and smartphones without GPS into navigation systems by fixing it on the car's dashboard. It has very good sensitivity, so you can also use it to improve the antenna strength/accuracy of smartphones with GPS. Inside a case made with a 3D printer, a GPS module, a Bluetooth module, and a USB board are integrated, making it as compact as possible. The large version is about 5mm wider than the standard version (sold separately), and the larger antenna makes positioning slightly faster. ● How to Use/Notes ・This is a listing for the GPS receiver only. ・10Hz operation ・Receives GPS, Michibiki, BeiDou, Galileo + SBAS ・Only the number of satellites used is displayed. ・USB is only used for power. ・Android devices only ・ABS material (suitable for use inside a car in midsummer) ・Since devices without GPS often cannot install navigation apps other than Google Maps from the Play Store, please check in advance whether you can install the app you want to use via PureAPK or similar.

A simple instruction manual will be included at the time of shipment, but we cannot guarantee support until you resolve issues such as compatibility with your device or app through trial and error. We can provide consultation within the scope of my knowledge. ● Regarding the RaceChrono app, we have confirmed that data acquisition is possible with the free version. If anyone has actually used it, please let us know your experience. ● August 5, 2025: The case design was revised and made slightly smaller.
