Quick tips regarding how to connect, protect, and disconnect U.FL connectors.
Note: Users should be aware that the transmission signal from the Wide Band 4G LTE Internal FPC antenna emmits orthogonally to the top surface (i.e. towards the camera in the image above). Additionally, from our experience the antenna runs better in the wire down orientation as well.

Battery

For remote LoRa applications, a Li-Po battery can be connected. Additionally, users may be interested in utilizing a solar panel and USB-C cable to recharge their battery.
