SL871L GNSS Module

Telit Cinterion's SL871L is the evolved variant of the SL871 family of modules based on the low-power Mediatek MT3333. It shares the same pinout and command interface of the standard SL871 but features an additional LNA, a DC block in the RF front end, and a second communication port selectable between I²C and UART. The SL871L also includes a switching power supply that reduces the total power consumption allowing a superior battery lifespan. Like the SL871, the SL871L is designed to support GPS, QZSS, GLONASS, Beidou, and Galileo. It can track three different constellations concurrently (GPS + Galileo + GLONASS or GPS + Galileo + Beidou). The SL871L is packaged in a 9.7 mm x 10.1 mm LCC package and provides navigation position through standard UART. The SL871L GNSS module can replace the Telit Cinterion SL871 with the observance of a few simple application rules.
