STMicroelectronics AEK-COM-GNSST31 Evaluation Board

STMicroelectronics AEK-COM-GNSST31 Evaluation Board features the Teseo-LIV3F global navigation satellite system (GNSS) module with embedded Teseo III receiver IC. The module offers superior accuracy and reduced time to first fix (TTFF) thanks to the on-board 26MHz temperature-compensated crystal oscillator (TCXO) and dedicated 32KHz 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.
