The GP‑20U7 from Sparkfun is a compact GPS receiver based on u‑blox 7 chipset. The module accurately provides position, velocity, and time readings as well possessing high sensitivity and tracking capabilities. Thanks to the low power consumption this receiver requires, the module is ideal for portable applications such as tablet PCs, smart phones, and other devices requiring positioning capability. This 56‑channel GPS module, that supports a standard NMEA‑0183 and u‑blox binary protocol, has low power consumption of 40mA@3.3V (max), an antenna on board, and -162dBm tracking sensitivity. With 56 channels in search mode and 22 channels “all‑in‑view” tracking, the module is quite the work horse for its size.
