Teseo-LIV3F based GNSS evaluation board for SPC5 microcontrollers

AEK-COM-GNSST31

Overview

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.
