The SparkFun SARA-R5 LTE GNSS Function Board is a robust development tool for u-blox's impressive SARA-R510M8S module designed to work with the MicroMod Ecosystem. The SARA-R510M8S combines u-blox's UBX-R5 cellular chipset with their M8 GNSS receiver chipset to provide a 5G-Ready wireless IoT device with positioning data all on a single chip. As an asset tracker, the LTE GNSS Function Board offers Secure Cloud LTE-M communication for multi-regional use. It also has an integrated u-blox M8 GNSS receiver for accurate positioning information.
The UBX-R5 chipset supports many different forms of data communication from full TCP/IP sockets and packet switched data, through HTTP Get/Put/Post, FTP (the SARA has a built-in file system), or ping to good old SMS text messaging! The built-in u‑blox M8 GNSS receiver provides accurate and reliable positioning with a separate GNSS antenna interface for an external antenna. The GNSS antenna and LTE connections are made via a pair of u.FL connectors. A nano SIM card slot is also included as well.
Utilizing our handy M.2 MicroMod connector, no soldering is required to connect it to your system. Simply match up the key on your processor and function board's bevelled edge connector to their respective key on the M.2 connector, then secure them to the Main Board with screws.
This Function Board provides access to the UART (default configuration) with a Processor Board. The USB pins are also broken out to a USB-C connector for diagnostic purposes. Status LEDs for 3.3V, Ring Indicator, LTE ON, and LTE Network Indicator are included. A button is included for LTE Power On.
Note: The SparkFun LTE GNSS Function Board - SARA-R5 uses the "01B" product version of the SARA-R5 module (specifically the SARA-R510M8S-01B).
