powering over this pin, please connect the ENABLE pin to GND so that the on board
regulator is disabled.
There are two radios on the Argon. A Mesh radio (nRF52840) and a WiFi radio (ESP32).
For the WiFi radio, we have provide a u.FL connector to plug in the WiFi antenna. This is
required if you wish to use the WiFi connectivity.
There are two options for the Mesh antenna on the Argon. 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.
