GNSS Module Exploits Teseo III Chip

STMicroelectronics’ Teseo-LIV3F module integrates essential features to speed application development and includes up to 16 Mb of flash memory for firmware updating or data logging without a backup battery. According to the company, the module enables engineering teams without extensive in-house RF expertise to leverage Teseo III advantages in creating new products in the industrial and consumer market segments like vehicle trackers, drones, anti-theft devices, pet locators, and systems for services such as fleet-management, tolling, vehicle sharing, or public transportation.


Said to be easy-to-use, the 18-pin, 9.7mm x 10.1mm module contains the Teseo III receiver with on-chip power management, UART, and I2C interfaces, alongside the flash memory, a stable temperature-controlled crystal oscillator (TCXO), and 32-kHz real-time clock (RTC). The documentation and tools delivered with the module contain all the C code needed to drive the module using the STM32 microcontroller, including the use of data-logging, odometer, and geo-fencing to aid development of value-added functionality.
