Hardware Assembly
Basic Assembly
The fastest way to get up and running with the LTE Stick is by connecting it to a computer through the USB-C connector and then using u-blox's mcenter software.
Soldered Assembly
New to soldering?
If you have never soldered before or need a quick refresher, check out our How to Solder: Through-Hole Soldering guide.
We specifically designed this board to fit on a breadboard with headers soldered to it for easy prototype circuit building with the LARA-R6. This assembly is strongly recommended for those who wish to use the LTE Stick with the SparkFun u-blox Cellular Library to make connections between the LTE Stick, microcontroller, and other hardware (where necessary).
Note
This assembly assumes the use of the SparkFun Thing Plus - ESP32 WROOM (USB-C) to make serial connections between the boards. If you are using a different microcontroller, adjust the serial connections between the two boards to the appropriate pins.
Start by soldering male headers to both sets of PTH pins on either side of the board. Next, connect the TXD and RXD pins on the LTE Stick to the Serial1 pins on the Thing Plus - ESP32 (USB-C). Finally, connect VUSB on the Thing Plus to VIN on the LTE Stick and connect the ground pins on both boards to each other. With everything wired up, your completed assembly should resemble the photo below:
