M-87 is an easy used 25.4 x 25.4 x 7 mm GPS module designed
by low power consumption MTK GPS solution. It provides superior sensitivity up
to -159dBm and fast Time-To-First-Fix in navigation application. The stable
performance of M-87 is your best choice to be embedded in your portable device
design, like PND for GPS service.
