Full size SAM GPS - MRO10037 
This is the next-generation of the uBlox SAM GPS module with the IST8308 compass. The mRo SAM GPS V2.0 is based on the old and now retired mRo mini SAM. The main difference is that it uses an ideal ground plane of 40mm x 40mm 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 grams! We saved some weight with a new generation, smaller rechargeable coin battery and a thinner PCB.
