Full size SAM GPS
Our M10037 board is based on the uBlox SAM M10Q GNSS module with the IST8308 compass. The main feature is that it has a closer-to-ideal ground plane of 42mm x 42mm as recommended by uBlox. This makes it a little heavier at 10.3 grams versus 7.6 grams, but it also gives you an increase from ~22 dB-Hz to ~34dB-Hz, which is a lot of gain for just 2.7 extra grams! We saved some weight with a new generation, smaller rechargeable coin battery and a thinner PCB.
