BETAFPV ELRS Nano Receiver 2.4Gh Nano RX FPV Long Range Drone Receiver RC Airplane Accessories
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.
- Weight: 0.7g (receiver only)
- Size: 12 x 19mm (0.5 x 0.7")
- Telemetry power: 20dbm
- Frequency bands (Nano receiver 2.4G version): 2.4GHz ISM
- Input voltage: 5V
- Antenna connector: IPEX MHF
Nano receiver 2.4G version diagram as shown below.
Nano receiver 915MHz version diagram as shown below.
1. 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);
2. 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 rate;
·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.
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 firmware for Betaflight 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 Configurator (for Betaflight) "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 automatically connect.
