ELRS Lite Receiver
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.
A ton of ExpressLRS items are available now!
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.
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 V1.1 can reach about 600 meters by equal conditions.

Flat Antenna V1.0 & V1.1
The ELRS Lite Receiver flat antenna V1.1 is coming to see you again. Range issues and failsafe at around 100 meters have been resolved compared with V1.0. Now, the V1.1 flat antenna receiver can reach 600 meters with BETAFPV Moxon TX Antenna (using BETAFPV Nano TX module).
Previously, the flat antenna V1.0 led to the failsafe at around 100 meters with an RSSI of -95dBm of this receiver, which did not reach the expected range compared with the beta version. However, it works great for indoor whooping and racing.
For customers who bought this receiver before March 2022 and have issues with it, we will refund you or send you a new one that fixes range issues.

Note: Now the firmware version of the Lite receiver tower antenna or flat antenna v1.1 manufactured by our company is ELRS 3.3.0; ELRS Innovative team has officially released version 3.3.0. If you want to flash ELRS official firmware, please download the latest ExpressLRS-Configurator or read our manual for flashing it. Significantly, the TX module and receiver have to be in the same ELRS version, otherwise, the frequency cannot match successfully.

Know More About ExpressLRS
ExpressLRS is an open-source RC link for RC applications. Everyone could find this project on Github or join the discussion in Facebook Group.
ExpressLRS is based on Semtech Lora SX127x or SX1280 hardware for RX and TX respectively. it aims to achieve the best possible link performance in both speeds, latency, and range. At 900 MHz a maximum of 200 Hz packet rate is supported. At 2.4 GHz a blistering 500Hz is currently supported with a custom OpenTX build. This makes ExpressLRS one of the fastest RC links available while still offering long-range performance.
More and more vendors start to support the ExpressLRS radio protocol in different parts, like radio transmitter with ELRS in stock, drone with built-in ELRS receiver, ELRS TX module for JR bay, or Nano bay. BETAFPV team take part in this project and provide a series of ExpressLRS components.
Configuration & Bind
ExpressLRS uses the Crossfire serial protocol (AKA CRSF protocol) to communicate between the receiver and the flight controller board. So make sure your flight controller board supports the 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 board is shown below.
Enable the corresponding UART (e.g. UART3 below) as a Serial Rx on Betaflight Configurator "Ports" tab.
On the "Configuration" tab, select "Serial-based receiver" on the "Receiver" panel, and select "CRSF" as the protocol. Telemetry is optional here and will reduce your stick update rate due to those transmit slots being used for telemetry.
The Lite receiver comes with offically major release V2.0.0 protocol and no Binding Phrase inlcuded. Lite receiver could enter binding status by power on/off three times.
- Plugin and unplug Lite receiver three times;
- Make sure the LED is doing a quick double blink, which indicates the receiver is in bind mode;
- Make sure the RF TX module or radio transmitter enter binding status, which sends out a binding pulse;
- If the receiver has a solid light, it's bound.
Note: Binding once and the receiver will store the binding information. Re-power and the connect successfully auto.
Note: If you reflash firmware of the receiver with your own Binding Phrase, please make sure the TX module has the same Binding Phrase. The RF TX module and the receiver will bind automatically in this situation.

I switched to ELRS and found it so easy to bind, the ELRS Lite was a perfect fit for 5” quad.
Nothing to say except it works and it easy to install and setup. Highly recommended if you are looking for a compact receiver without having to mount an external antenna.
They responded to a replacement for a flat antenna problem on the ELRS Lite Receiver. Thanks!
I love the form factor....small fits almost anywhere
Love this small little receiver !
Works like a charm & easy to set up.
Flashing the firmware via WIFI is great & just following the instructions, easy to complete.
Works amazingly well with my Lite Radio 2 SE which I also converted to ELRS.
Using a bind-phrase on both devices makes binding easy-peasy ! [switch on & go!]
Love it !
