Boron setup
This page walks you through unboxing and setting up a Boron, a cellular development board with Bluetooth LE. By the end, the Boron will be powered up and ready to add to your Particle account.
Unboxing

What's in the box depends on whether you purchased the Boron Kit or just the Boron device. Check the contents before you start.
Boron Kit (BRN404XKIT)
- Boron LTE development board (BRN404X with EtherSIM)
- Mini breadboard
- Cellular flex antenna (PARANTC41EA)
- Micro-USB cable
- Starter components: two 220 Ω resistors, one red LED, and one photodiode
Boron (board only)
- Boron LTE development board (BRN404X or BRN402)
- Cellular flex antenna (PARANTC41EA)
Warning:
The Boron must always be used with the included certified cellular antenna to remain compliant with regulatory certifications.
What you'll need
- A Boron (BRN404X or BRN402)
- The cellular antenna. It is required and must be attached before you power the device.
- A micro-USB cable for power and data
- A computer (Windows, Mac, or Linux), which you'll use to set up the device and to program it with Particle Workbench
- Optionally, a Li-Po battery for portable or backup power
Prepare the hardware
- Connect the cellular antenna to the u.FL connector on the Boron.
- If you want to use a battery, connect the Li-Po battery.
- Connect the micro-USB cable between the Boron and your computer. This provides both power and a data connection.
