SL871L

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.
