Med size SAM GPS - MRO10038 
WARNING
Unmaintained site notice. Information may be outdated.
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.
Compared to the IST, the IST8308 has less temperature drift, more sensitivity, and a built-in noise filter. Older GPS versions used the LIS3MDL, which doesn’t even come close to the performance of the old IST8310, let alone the IST8308.
mRo SAM GPS + IST8308 Mag (Med Size) Supports: Ardupilot and PX4.
