Check this product’s supported frequencies in the description/specs. - If you intend to operate outside shared/licence‑exempt conditions (e.g. in other bands, at higher power, with high‑gain antennas, or extended duty cycles), you must have the appropriate authorisation. **For use in other regions** - Follow the spectrum rules for your country/region and select frequencies and settings accordingly. A declaration of use will need to be submitted during checkout. ## How to buy - **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=GPS-18031:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart. - **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/GPS-18031:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.) - **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there. - **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works) - **Payment methods, purchase orders, policies and contact details:** https://core-electronics.com.au/llms.txt ## Description The SparkFun SARA-R5 LTE GNSS Breakout is a robust development tool for u-blox's impressive SARA-R510M8S LTE-M / NB-IoT module. The SARA-R510M8S LET-M / NB-IoT module combines u-blox's UBX-R5 cellular chipset with their M8 GNSS receiver chipset to provide a 5G-Ready wireless IoT device complete with positioning data all on a single chip. 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), 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. Both the GNSS antenna and LTE connections are made via a pair of SMA connectors. This breakout routes nearly all of the functional pins on the SARA-R510M8S module to user interfaces (USB or plated-through hole) so you can take full advantage of all of the features available on this impressive LTE/GNSS module. The SARA-R5's UART interface can be configured into one of five variants, providing connectivity over one or two UARTs. A separate USB port provides access to the SARA's trace log for diagnostic purposes. This breakout provides access to all three interfaces (UART1, UART2 and SARA Diag) via three separate USB-C connections. All eight 3.3V serial signals are available on a 0.1"-pitch breakout header. Separate 0.1"-pitch headers break out the SARA's I2C bus, power pins as well as GPIO pins for various functionalities.
