Telit, a global enabler of the Internet of Things (IoT), announced the release of the SE873K5, the latest addition to its SE873 family of modules and the natural migration path from SE873 and SE873Q5. Based on AG3335 series from Airoha, the SE873K5 is a new multi-constellation receiver in the ultra-high L1 frequency band, with a 7x7x2.25 mm QFN-like semiconductor package including embedded SPI flash, RTC and TCXO. Due to its compact size, the latest generation chipset and the advanced power modes, the SE873K5 brings the benefits of low cost, small form factor and good electrical and thermal performance, which is ideal for applications such as wearables, fleet tracking, drones and more.
The SE873K5 simultaneously tracks and navigates all four GNSS constellations — GPS, Galileo, GLONASS and Beidou — providing GNSS information over a UART, I2C or SPI interface serial port using the NMEA Protocol. In addition to its low-power processing core that delivers several customizable power-saving modes, the SE873K5 optimizes current draw at module wake-up by supporting both local- and server-based Assisted GNSS (A-GNSS) for improved TTFF, while Satellite Based Augmentation System (SBAS) corrections from WAAS, EGNOS, MSAS or GAGAN increase positioning accuracy. Additionally, the internal flash memory allows firmware updates and customization, as well as ephemeris predictions storage.
