GPS Receiver - GP-735 (56 Channel)

The GP-735 GPS smart antenna receiver from Sparkfun is a compact, ultra-efficient device that boasts impressive performance. Despite its slim design, measuring only 35 x 8 x 6.5 mm, it offers -162dBm tracking sensitivity and a rapid 29-second cold start time. This makes it an ideal solution for projects requiring a compact, high-performance GPS module.

Equipped with a 56-channel GPS module based on the uBlox 7th generation chipset, the GP-735 operates at a voltage of 3.3~5.5V. It features an onboard antenna and provides TTL serial connectivity. Its 1Hz update rate is sufficient for most applications, but it can be boosted to 10Hz if required. Whether it's for tracking a pet, designing a drone, or developing an autonomous vehicle, the GP-735 is a reliable choice.

The GP-735 model that Sparkfun offers is the "T" variant, which uses TTL-UART, rather than USB. It is compatible with 6-pin 1mm pitch JST type cables and connectors, which can be found in the recommended products section.
