SparkFun LTE Stick - LARA-R6

SparkFun LTE Stick - LARA-R6 (CEL-23618)

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 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. 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. 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).
