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 the Nano receiver and a Lite receiver?
The Nano receiver (2.4G version) is the first and (so far) the only receiver with a 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 their telemetry power is as what the RF chip SX1280 came with 17mW.
Besides, the Nano receiver comes with a normal external Dipole T antenna. Lite receiver has SMD ceramic antenna and in theory, it would have less range.
High recommend the Nano receiver if the space is enough. On 65-85mm whoop drones with limited space and need lightweight, the Lite receiver is a better choice.
