Description

The AEK-COM-GNSST31 evaluation board is based on the certified Teseo-LIV3F

global navigation satellite system (GNSS) module with embedded TeseoIII single die

standalone positioning receiver IC.

The tiny, affordable, and easy-to use module guarantees superior accuracy and

reduced time to first fix (TTFF) thanks to the on-board 26 MHz temperature

compensated crystal oscillator (TCXO) and dedicated 32 KHz real-time clock (RTC)

oscillator.

The evaluation package is used in conjunction with the X-CUBE-GNSS1 firmware to

provide the necessary acquisition, tracking, navigation and data output functionality

without external memory support.

The AEK-COM-GNSST31 evaluation board can be readily connected with an SPC5

MCU for automotive application development as part of the AutoDevKit™ initiative.
