The Xenon is a low cost mesh-enabled development board that can act as either an
endpoint or repeater within a Particle Mesh network.
The Xenon is mesh only and designed to function as the endpoint of your IoT network. It is
based on the Nordic nRF52840 and has built-in battery charging circuitry so it’s easy to

connect a Li-Po and deploy your local network in minutes.
The Xenon is best for connecting sensors, motors, pumps, valves, and points of datainterest. Pair it with an Argon or Boron gateway to get all that great data into the Device
Cloud.

The USB port is the easiest way to power up the Xenon. Please make sure that the USB
port is able to provided at least 500mA. Power from the USB is regulated down to 3.3V by
the on board Torex XC9258A step-down regulator.
The pin is internally connected to the VBUS of the USB port. The typical output should be
around 4.5 to 5 VDC when the device is plugged into the USB port and 0 when not
connected to a USB source. You can use this pin to power peripherals that operate at such
voltages. Do not exceed the current rating of the USB port, which is nominally rated to
500mA. This pin is also protected with an internal fuse rated at 1000mA.

If you want to make your projects truly wireless, you can power the device with a single
cell LiPo/Lithium Ion (3.7V). The Xenon has an on board LiPo charger that will charge and
power the device when USB source is plugged in, or power the device from the LiPo alone
in the absence of the USB.
NOTE: Please pay attention to the polarity of the LiPo connector. Not all LiPo
batteries follow the same polarity convention!
This pin is internally connected to the positive terminal of the LiPo connector. You can
connect a single cell LiPo/Lithium Ion or a DC supply source to this pin for powering the
Xenon. Remember that the input voltage range on this pin is 3.6 to 4.2 VDC.
This pin is the output of the on board 3.3V step-down switching regulator (Torex
XC9258A). The regulator is rated at 1000mA max. When using this pin to power other
devices or peripherals remember to budget in the current requirement of the Xenon first.
This pin can also be used to power the Xenon in absence of the USB or LiPo power. When

powering over this pin, please connect the ENABLE pin to GND so that the on board
regulator is disabled.
There are two options for the Mesh antenna on the Xenon. It comes with an on-board PCB
antenna which is selected by default in the device OS and a u.FL connector if you wish to
connect an external antenna. If you wish to use the external antenna, you'll need to issue
an appropriate command in the firmware.
The following antenna is optional, as the Xenon comes with an on-board PCB antenna.

Note: All GPIOs are only rated at 3.3VDC max.
The Xenon has a dedicated 10 pin debug connector that exposes the SWD interface of
the nRF5280. This interface can be used to debug your code or reprogram your Xenon
