ELRS Nano Receiver
BETAFPV Nano 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 ExpressLRSÂ items are available now!
For micro drones, high recommend the smaller Lite receiver.
Recommend ExpressLRS Recovery Dongle for unbricking the receiver.

Diagram
Nano receiver 2.4G version diagram as shown below.
Nano receiver 868MHz/915MHz version diagram as shown below.
Note:Â The firmware version of the Nano receiver and module manufactured by our company is ELRS 1.0.0-RC5 (the fifth test version before release);
ELRS Innovative team has officially released version 1.0.0. Based on the version, we have some updates:
- 2.4G Nano TX Module supports 500Hz refresh rateï¼›
- Short press the button on the Nano module 3 times to get into the binding status.
We suggest our customers upgrade their modules and receivers' ELRS version to 1.0.0. Significantly, the 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 & BindÂ
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 Nano 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.
Nano receiver could enter binding status by power on/off three times.
- Plugin and unplug nano 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.

For me buying 868mhz eLRS components was a big experiment with high potential for a total fail. I intended to use the eLRS system for replacing a museal 40mhz r/c system used for my r/c submarines since many years. Nobody was able to answer the question if a digital radio system running at such high frequency could work for a fully submeged sub, as usually range will dramatically decrease with increasing frequency and conductivity of water. E.g. an usual 2.4ghz r/c system will already fail if the rx antenna gets submerged for just a few centimeters.
After cautious testing (with the optional longer rx antenna) I can say it was a full success! I have at least same range as with the old system before and in addition I have now telemetry as well in combination with a Matek CRSF-PWM-C board. Meanwhile both submarines are finally retrofitted for eLRS and have already many hours operational time without any incidents. I hope BetaFpv will continue supporting eLRS for both 868/900mhz and 2.4ghz, so other special applications may benefit from this technology, too.
I love this receiver! I had never such so a good and innovative system before!
Great product
I order BETAFPV ELRS Nano Receivers shipping was fast. Receivers are flashed to ELRS 1.0.0. by default, you will need to flash to version of your choice. I'm happy with my purchase. All my quadcopters are now on ERLS.
Great System!
