BAYCKRC ELRS 2.4GHz FPV Receiver ExpressLRS Nano Receiver for FPV Racing Drones and Micro Quadcopters

Specification: Model: ELRS 2.4G NANO Name: ExpressLRS Receiver RF: Freq: 2.4GHz IC: SX1281+ESP8285 TX Power: 100mW Color: Black Connector: IPEX 1 Input Power: 3.6-5.5V Weight: 0.4g (receiver only) Size: 11mm*18mm Frequently Asked Questions Q: Can this receiver bind with other brands transmitters? A: The ELRS project is open-source, so any transmitter using the ELRS protocol, regardless of brand, can bind with this receiver, provided the following three conditions are met: 1.The frequency must be the same, either 2.4G or 915MHz. 2.The firmware versions must match. For example, if the transmitter is running firmware version 2.5.0, the receiver must also be running version 2.5.0. 3.Both must either have no binding password or the same binding password set. Q: How do I enter binding mode? A: After soldering the receiver, quickly power the aircraft three times: "power on and off immediately - power on and off immediately - power on and leave on," with intervals within 1.5 seconds. If done correctly, the receiver's LED will flash twice rapidly, indicating it is in binding mode. Then, press the bind button on the transmitter to bind. Once bound, the receiver's LED will stay lit. Q: Why can't my receiver enter binding mode the first time I use it? The LED stays lit. A: Through multiple cases, we found that some flight controllers have abnormal TX/RX ports, causing the receiver to enter boot mode upon power-up. Simply switching to another TX/RX port on the flight controller will resolve this issue. Q: Why is my receiver's LED flashing rapidly? A: If the receiver is powered on but not in binding mode, or if it has already been bound but the transmitter is not turned on, the receiver will automatically enter WiFi update mode after 60 seconds without a signal, indicated by rapid LED flashing. Q: How do I enter WiFi update mode to flash the receiver's firmware? A: As mentioned above, simply power on the receiver and leave it. After about 60 seconds, it will enter WiFi update mode, indicated by rapid LED flashing. The BAYCK Series RX2.4G Receiver is based on the open-source ExpressLRS architecture and program.
