STMicroelectronics | AEK-COM-GNSST31

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.
