Description: This is an eval board for the ET-312 GPS module. We developed this eval board for it, but messed up the ET312 footprint. We had to significantly modify the back of the PCB to get these to work. Board works and GPS gets a good lock. These are ding/dent because of the PCB mods. This is the only stock we will have.
