Xenon
Overview
The Particle Xenon is a low-cost mesh-enabled development board based on the Nordic Semiconductor nRF52840 SoC. The board was developed by Particle Industries and has an SWD connector on it for programming.
It is equipped with a onboard LIPO circuit and conforms to the Adafruit Feather formfactor.
The Particle Xenon board provides support for the Nordic Semiconductor nRF52840 ARM® Cortex®-M4F SoC with an integrated 2.4 GHz transceiver supporting Bluetooth® Low Energy and IEEE® 802.15.4.
For more information about the Particle Xenon board:
Hardware
On the front of the board are RGB-LED, LED and LIPO circuitry. The RGB-LED is controlled by the nRF52840 via GPIO pins.
Power supply
The board is optimized for low power applications and supports two power source configurations, battery and micro USB connector.
It contains circuitry for LIPO usage and can be charged via the USB port.

Programming and Debugging
Applications for the particle_xenon board configuration can be
built and flashed in the usual way (see Building an Application
and Run an Application for more details).
Flashing
Build and flash an application in the usual way, for example:
# From the root of the zephyr repository
west build -b particle_xenon samples/basic/blinky
west flash
Debugging
You can debug an application in the usual way. Here is an example for the Hello World application.
# From the root of the zephyr repository
west build -b particle_xenon samples/hello_world
west debug
