## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=CEL-23618:1` (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/CEL-23618:1.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)

## Description

The SparkFun LTE Stick provides a development and prototyping platform for the LARA-R6 LTE Cat 1 module from u-blox™. The LTE Stick uses the LARA-R6401 version, which supports both data and voice for North America and works with LTE bands used by these mobile networks: AT&T, Verizon, T-Mobile, and FirstNet. The board includes a nanoSIM card slot for users to select their preferred network. Check with your network provider for compatibility with the LARA-R6.

The LARA-R6 works on multiple LTE FDD frequency bands (2, 4, 5, 12, 13, 14, 66, and 71) and includes a host of common features users expect from u-blox modules, including uFOTA (over-the-air firmware update), Root of Trust, secure boot/update, jamming detection, antenna and SIM detection, and much more.

The LTE Stick routes the UART and I2S interfaces to a 0.1in.-spaced plated-through-hole (PTH) header along with the Reset and Power On signals, and Sparkfun designed the board to mount onto a breadboard specifically for easy prototyping. Since the LARA-R6401 supports data *and* voice, you can use the LTE Stick with the right parts (such as an [audio codec](https://core-electronics.com.au/sparkfun-audio-codec-breakout-wm8960-qwiic.html), [microphone](https://core-electronics.com.au/components/microphones.html), [speaker](https://core-electronics.com.au/speaker-pcb-mount.html), & [microcontroller](https://core-electronics.com.au/sparkfun-thing-plus-esp32-wroom-usb-c.html)) and code; you can make your own breadboard telephone!

The board has two SMA connectors for the LARA-R6's primary and secondary antennas. The primary antenna sends and receives data, whereas the secondary antenna is receive only. Power to the board is provided either over the USB-C connector (recommended) or the VIN PTH pin (**6V Max**). The board defaults to use the higher voltage input. Lastly, the board also includes test points for advanced users to solder to for the I2C interface, secondary UART, and four GPIO pins (IO1, IO2, IO3, and IO6).
