BetaFPV ELRS Lite RC Radio Receiver - BF-02

BETAFPV Lite receiver is based on the ExpressLRS project, an open-source RC link for RC applications. ExpressLRS aims to achieve the best possible link performance in both speeds, latency, and range. This makes ExpressLRS one of the fastest RC links available while still offering long-range performance.

Nano RX or Lite RX

What is the major difference between Nano receiver and Lite receiver?

Nano receiver (2.4G version) is the first and (so far) the only receiver with power amplifier (PA+LNA). It has 100mW telemetry output and better sensitivity when longer range. Lite receiver doesn't have a PA/LNA on them, so its telemetry power is as what the RF chip SX1280 came with 17mW.

Beside, Nano receiver comes with normal external Dipole T antenna. Lite receiver has SMD ceramic antenna and in theory it is not so long range.

High recommend the Nano receiver if the space is enough. On 65-85mm whoop drones with limited space and need light weight, Lite receiver is a better choice.
