This 2.4G ELRS receiver is a nano size and powerful receiver. It is only 11mm x 19mm in size and 1.18g in weight (including antenna). About the performance, it features PA and LNA, which boosts signal strength, making it perfect for freestyle quads and long-range builds. External UFL antenna provides better range and durability.

Kudos to ELRS developers team for all of the help and testing during the development of this ELRS receiver.

Features:

• Integrated low-power and highly-integrated ESP32-C3 MCU
• Temperature compensated crystal oscillator (TCXO) is used to provide higher frequency accuracy.
• Integrated LNA boosts incoming signal, giving you a better signal reception.
• Integrated PA boosts outoing signal stregth. The receiver output is adjustable at 10mW, 25mW, 50mW and 100mW.
• External UFL antenna provides better range and durability.

Receiver Wiring

Please wire the receiver to the FC as in the diagram below. You must wire the receiver to a spare full same UART (TX and RX) on the FC.

FC Betaflight Configuration

1. Under Ports tab, enable the seria rx on the corresponding UART you wired the receiver to.

2. Under Receiver tab, choose Serial (via UART) and CRSF serial receiver provider.

Binding

1. Recommended Binding Method
Our ELRS receiver is in bind mode by default, so you can just plug in the battery and start binding. Please check out detailed procedure as below.

1. Power on the receiver
2. LED is double-blinking, indicating the receiver is in bind mode.
3. Initiate the bind process on your radio controller
4. If the LED is solid on, then the receiver is bound.

2. Unique Pharse Binding MethodBefore flashing or updating the ELRS firmware, you can select a unique binding phrase in the ELRS configurator or WebUI. You can check out details onExpressLRS website.

3. Traditional Binding Method

1. Turn off your radio controller
2. Powercycle the receiver for three times
3. LED is double-blinking, indicating the receiver is in bind mode.
4. Power up your radio controller and initiate the bind process
5. If the LED is solid on, then the receiver is bound.

Package Includes:

• 1 x TUNERC ELRS Nano Receiver 2.4GHz (PA+LNA)
