BETA FPV ELRS Lite Rx
The 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 terms of speed, latency and range. This makes the ExpressLRS one of the fastest RC links available while still offering long-range performance.
Lots of ExpressLRS items are now available!
Nano RX or Lite RX
What is the main difference between Nano receiver and Lite receiver?
The Nano receiver (2.4G version) is the first and (so far) only receiver with a power amplifier (PA+LNA). It has 100mW telemetry output and better sensitivity when at long range. The Lite receiver does not have a PA/LNA, so its telemetry power is that of the SX1280 RF chip with 17 mW.
Additionally, the Nano receiver comes with a regular external T-dipole antenna. The Lite receiver has an SMD ceramic antenna and in theory is not as long range.
I highly recommend the Nano receiver if you have enough space. On 65-85mm whoop drones with limited space and needing light weight, the Lite receiver is a better choice.
Tower antenna or flat antenna
The new flat antenna Lite receiver features an ultra-thin 3mm board and a light weight of 0.53g, requiring less mounting space on drones with limited space. In addition, a solid flat antenna without rough parts can resist shock, making the receiver not so fragile.
Whatever the tower antenna or flat antenna, both versions perform well in terms of control, range and stability, giving pilots a good flying experience. Below the table is basic information for two antennas. It is proven that both antennas have almost the same gain performance. However, the efficiency for the flat antenna is better than the tower antenna. Despite this, the tower antenna and flat antenna can reach the range of about 600m using TX with the same output power and frequency.
| Tower antenna | Flat antenna | |
| Weight | 0.47g | 0.53g |
| To measure | 10mm*10mm*6mm | 11mm*10mm* 3mm |
| I earn | 3.3dB | 3.2dB |

| Return loss | <-7 | <-7 |
| Range (TX 100 mW 150 Hz) | About 600 m | About 600 m |

Note: The firmware version of the Lite receiver produced by our company is ELRS 1.0.0; The ELRS Innovative team has officially released version 1.2.0, which is not compatible with version 1.0.0. We suggest our customers update the ELRS version of this receiver to 1.2.0 if necessary. Significantly, the TX module and receiver must be in the same ELRS version, otherwise the frequency cannot match correctly.
Note: Please upgrade via cable if you flash ELRS V1.1.0 firmware on your Lite receiver. Otherwise, the Lite receiver will enter a boot loop if updated ELRSV1.1.0 via WIFI.
Learn more about ExpressLRS
ExpressLRS is an open source RC link for RC applications. Everyone could find this project on Github or join the Facebook Group discussion.
ExpressLRS is based on Semtech Lora Hardware SX127x or SX1280 for RX and TX respectively. aims to achieve the best possible link performance in both speed, latency and range. At 900 MHz a maximum packet rate of 200 Hz is supported. At 2.4 GHz an incredible 500Hz is currently supported with a custom OpenTX build. This makes the ExpressLRS one of the fastest RC links available while still offering long-range performance.
More and more vendors start to support ExpressLRS radio protocol in different parts, such as radio transmitter with ELRS in stock, drone with integrated ELRS receiver, ELRS TX module for JR housing or Nano housing. The BETAFPV team takes part in this project and provides a set of ExpressLRS components.
Setup and binding
ExpressLRS uses the Crossfire Serial Protocol (AKA CRSF protocol) to communicate between the receiver and the flight controller board. So make sure your flight control board supports CRSF serial protocol. Next, we use the flight controller with Betaflight firmware to show how to set up the CRSF protocol.
The connection between the ELRS Lite receiver and the FC card is shown below.
Enable the corresponding UART (e.g. UART3 below) as Serial Rx in the "Ports" tab of Betaflight Configurator.
In the "Configuration" tab, select "Serial Receiver" in the "Receiver" panel and select "CRSF" as the protocol. Telemetry is optional here and will reduce the update rate of the stick due to the transmit slots used for telemetry.
The Lite receiver comes with the officially major release V1.1.0 protocol and without Binding Phrase included. The Lite receiver may enter the binding state by turning power on/off three times.
- Plug and unplug the Lite receiver three times;
- Make sure the LED is performing a quick double flash, which indicates that the receiver is in pairing mode;
- Make sure the RF TX module or radio transmitter enters link state, which sends link pulse;
- If the receiver has a solid light, it is bound.
Note: Bind once and the receiver will store the binding information. Turn it back on and connect successfully automatically.
Note: If you update the receiver firmware with your own binding phrase, make sure the TX module has the same binding phrase. The RF TX module and receiver will connect automatically in this situation.

Under the 24-month Legal Guarantee, Drone24Hours is responsible to the consumer for any defects in conformity that cannot be detected at the time of purchase.
The lack of conformity exists when the product is not suitable for the use for which it is normally intended, does not conform to the description or does not possess the qualities promised by the seller, does not offer the qualities and performances usual for a good of the same type, is not suitable for the particular use desired by the consumer if brought to the attention of the seller at the time of purchase and accepted by the seller (art. 129 of the Consumer Code).
Any lack of conformity which becomes apparent within 24 months of the date of purchase of the goods must be reported within 2 months of the date of discovery of the defect.
Unless proven otherwise, it is presumed that any lack of conformity that becomes apparent within 6 months of delivery of the goods already existed on that date. In the event of a lack of conformity, the consumer has the right to have the conformity of the goods restored, free of charge, by repair or replacement (art. 130 of the Consumer Code).
The consumer may ask, at his choice, the seller to repair the goods or replace them, free of charge in both cases, unless the requested remedy is objectively impossible or excessively expensive compared to the other. Repairs or replacements must be carried out within a reasonable time from the request of the Consumer; the average time for returning the product to the Consumer is 20 days.
If Drone24hours is unable to return the repaired product within the maximum period of 60 days, the consumer may request one of the alternative remedies (replacement, termination of the contract, price reduction).
Drone24Hours will send the product for any repairs to the Technical Assistance Center authorized by the Manufacturer.
What happens if the Service Center does not find the lack of conformity?
If the lack of conformity is not found, Drone24Hours will communicate the estimate to the Customer, who can decide whether or not to carry out the repair at his own expense. In this case, any transport costs and diagnosis of the defect requested by the Assistance Center will be borne by the Customer.
