A 8 Channel GPS module with internal antenna. It supports I2C and serial communiction betwen the host MCU (e.g. OOPIC and Basic Stamp etc.) and the device. Technical Specifications and Product Details.
The DS-GPM is a highly integrated Global Positioning System allowing your robotic application to determine its location on the earth's surface. Specifically targeted at OOPic / BASIC Stamp type embedded control applications and the Personal Computer user the GPM features I2C and RS232 communication. GPS data received by the DS-GPM is stored within internal registers which are updated once per second and include: Latitude (i.e. vertical), Longitude (i.e. horizontal), Altitude (metres), Time & date (UTC), Heading (True & Magnetic), Speed (kilometres per hour) and Satellites detected. In addition the DS-GPM features an on-board fully configurable four line TTL IO port and a four line analogue input port with automatic measurement. Here is the datasheet.
