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.
Tower Antenna or Flat Antenna
New lite receiver with a flat antenna features a 3mm extra-thin board and 0.53g lightweight, which requires less assembly space on drones with limited space. Besides, solid flat antenna without irregular parts can withstand crashes, making the receiver not so fragile.
Whatever tower antenna or flat antenna, both versions perform well in control, range and stability, bringing a good flight experience to pilots. Below chart is the basic information for two antennas. It is shown that both antennas have almost the same performance in gain. However, the efficiency for flat antenna is better than tower antenna. In spite of that, tower antenna and flat antenna can reach the range of about 600m by using TX with the same output power and frequency.

Lite receiver with flat antenna 2.4G version diagram as shown below.
Note: The firmware version of the Lite receiver manufactured by our company is ELRS 1.0.0; ELRS Innovative team has officially released version 1.2.0, which is not compatible with the 1.0.0 version. We suggest our customers upgrade this receivers' ELRS version to 1.2.0 if needed. Significantly, the TX module and receiver have to be in the same ELRS version, otherwise, the frequency cannot match successfully.
Note: Please upgrade via cable if you flash ELRS V1.1.0 firmware to the lite receiver. Otherwise, the lite receiver will enter in a boot loop if upgraded ELRSV1.1.0 via WIFI.
