GPS Module - Venus638FLPx-L 20Hz (14 Channel)

by Sparkfun

Venus638FLPx is a high performance, low cost, single chip GPS module targeting mobile consumer and cellular handset applications. It offers very low power consumption, high sensitivity, and best in class signal acquisition and time-to-first-fix performance.

Venus638FLPx contains all the necessary components of a complete GPS module, includes 1.2dB cascaded system NF RF front-end, GPS baseband signal processor, 0.5ppm TCXO, 32.768kHz RTC crystal, RTC LDO regulator, and passive components. It requires very low external component count and takes up only 100mm2 PCB footprint.

Note: According to the manufacturer's specifications, the IC requires a 24 hour pre-bake at 125C before SMD mounting in order to prevent issues with moisture .
