Beskrivelse

Delin Comm DM2222-R is a complete GPS engine module that features super sensitivity, ultra low power and small form factor. The GPS signal is applied to the antenna input of module,and a complete serial data message with position, velocity and time information is presented at the serial interface with NMEA protocol or custom protocol. Its -165dBm tracking sensitivity extends positioning cover age into place like urban canyons and dense foliage environment where the GPS was not possible before. The small form factor and low power consumption make the module easy to integrate into portable d evice like PNDs, mobile phones, cameras and vehicle navigation systems.
