This miniature GPS module uses the compact GR10/MN1010 GPS module in conjunction with a GPS chip antenna and a SMA661AS 18dB LNA from ST Electronics. This board is about as simple as it gets, having only 3 connections: VCC, ground and a TX line. Power the board from a single 3.5V-6V source (ideal for single Lipo cell operation) and the unit will output NMEA serial sentences containing all the GPS data (location, satellites in view, altitude, time, speed, heading, etc).
