Using the Radiomaster ExpressLRS RP1 2.4GHz Nano Receiver is quite straightforward. First, connect the 65mm UFL 2.4GHz T Antenna to the UFL antenna socket. Then, power it up with a 5V power source. You can use your PC or mobile phone to access the built - in WebUI via WIFI to upgrade the firmware and configure the receiver. When it comes to using it in your Whoops, drones, or fixed - wing models, just find a suitable spot due to its small size and install it. Some things to note: Make sure the power source is stable at 5V to avoid any issues. When handling the antenna, be gentle as it's a delicate part. For maintenance, keep it clean and dry. If you notice any overheating, check the PCB design as it's been improved for heat dissipation. If there are any soldering needs, take advantage of the improved solder pads. Always refer to the user manual for more detailed instructions.
