SL871L

Multi-Constellation Positioning GNSS

The SL871L delivers low power consumption and excellent navigation in the industry standard 10.1 x 9.7 mm footprint. An ideal solution for a variety of applications, from weather balloons to dense urban environments, the SL871L includes AGPS, which allows faster time to first fix (TTFF) and low power consumption for longer battery life.

  • Industry standard 10.1 x 9.7 mm footprint
  • AGPS for faster TTFF
  • Ultralow power
  • GPS, GLONASS, BeiDou and Galileo
  • Additional LNA for top-level RF sensitivity

Product Brief

Product Description

The SL871L is the latest variant of the SL871 family of modules based on the low-power Mediatek MT3333.

The SL871L shares the same pinout and command interface of the legacy SL871, but it features an additional LNA, a DC block in the RF frontend and a second communication port selectable between I2C and UART. The new SL871L also includes a switching power supply that reduces the total power consumption allowing a superior battery lifespan.

Form Factor Family

The SL871 miniature form factor is a 10.1 x 9.7 mm, 18-pad castellated LCC package ideal for manual and automated manufacturing systems.
