BETAFPV ELRS Lite Receiver

BETAFPV ELRS Lite Receiver

Description:

Building on the open-source ExpressLRS framework – renowned for delivering ultra-low latency, blistering speeds, and exceptional range – the upgraded Lite Receiver flat antenna V1.2 now features an extra-thin 3mm board, 0.46g ultra-lightweight design and enlarged soldering pads. Optimized impedance matching elevates signal reliability and sensitivity, enabling 300m range at 25mW transmitter power and up to 1000m at 50mW, pushing the boundaries of long-range potential in micro-sized receivers.

Enhanced Signal Reliability & Sensitivity

The flat antenna V1.2’s optimized impedance matching unlocks a transformative leap in signal reliability and sensitivity. Where the original flat antenna V1.1 achieved 500-600m at 50mW transmitter power/500Hz, the V1.2 now delivers a robust 1000m under identical conditions – alongside superior signal consistency. This precision-tuned design minimizes packet loss during high-speed maneuvers and enhances low-power efficiency, ensuring crisp responsiveness at 25mW (300m range) and unwavering stability at max output.

Lightweight Design, Simplified Installation

Responding to community feedback, the flat antenna V1.2 now features enlarged soldering pads designed to simplify installation and reduce errors – a critical upgrade for novices and seasoned builders alike. Combined with a 13.2% weight reduction (now just 0.46g), the updated design retains its compact footprint while shedding unnecessary mass, freeing up crucial weight budgets for performance-focused builds.

BETAFPV ExpressLRS Receivers

Selecting the right receiver is crucial for optimal quadcopter and RC model performance. BETAFPV’s comprehensive  – featuring the ELRS Lite, Nano, Micro, and our newest SuperD receivers – delivers tailored solutions to meet every pilot’s FPV requirements.

Nano RX vs. Lite RX

The nano receiver (2.4G version) is the first receiver with power amplifier (PA+LNA), delivering 100mW telemetry output and better sensitivity for longer range. In contrast, the Lite Receiver doesn’t have a PA/LNA, so its telemetry power is limited to the SX1280 RF chip’s native 17mW output.

Another key difference is the antenna: the Nano Receiver comes with a standard external Dipola Antenna, while the Lite Receiver uses a SMD ceramic antenna, which typically offers shorter range.

For best performance, we highly recommend the Nano Receiver if your build has enough space. However, for racing and 65-85mm whoop drones, the Lite Receiver remains the better choice.

Flat Antenna vs. Tower Antenna

The new Lite Receiver flat antenna V1.2 features an extra-thin 3mm board and 0.46g lightweight design, ideal for drones with space constraints. Its low-profile flat antenna can withstand crashes, delivering durability compared to protruding tower antennas.

While both antennas share similar gain and return loss characteristics, the flat antenna V1.2’s optimized impedance matching achieves better signal reliability and sensitivity – extending operational range to 1,000m (versus the discontinued tower antenna’s 600m). This upgrade focuses entirely on perfecting the crash-resistant flat antenna design, delivering pilots unprecedented range and durability in the most compact form factor available.

The connection between the ELRS Lite Receiver and the FC board is shown below.
