Soldering - iRangeX ExpressLRS ELRS 2.4GHz Nano RX CRSF SBUS Ultra-Low Latency Open-Source Receiver

iRangeX ExpressLRS ELRS 2.4GHz Nano RX CRSF SBUS Ultra-Low Latency Open-Source Receiver for RadioMaster Pocket TX16S Mark II Jumper T-PRO T20 T20S Radio Transmitter

Introduction: This ExpressLRS series nano receiver utilizes LoRa technology based on the Semtech SX1280/SX1281 chipset combined with an ESP8285 processor, achieving ultra-low latency and long-range communication. The system supports a packet rate of up to 1000 Hz, ensuring smooth and delay-free control. Due to it's open-source nature and widely support, more features are still being continuously developed.

Specification:

Brand: iRangeX

Model: 

Operating voltage: 4-5.5V Operating current: <=150mA Operating frequency: 2.4G RF power: 100mW Max Weight: 0.7g(antenna not include) Size: 17x10x3mm (antenna not include) Output Protocol: CRSF or SBUS Processor: ESP8285

LUA script: https://github.com/ExpressLRS/ExpressLRS/tree/master/src/lua

Bind:

1. Connect the receiver to your flight controller, Beware that, the receiver's TX pin should be connected to the flight controller's RX pin, the RX should be connected to the flight controller's TX. The RX can be left unconnected in certain cases. 2. Refer to the website above, download the latest LUA script and copy it to the script folder of your transmitter's SD card. 3. Power on your transmitter, enter Model Settings menu, turn on External RF, and select 'CRSF' mode. 4. Enter System Settings menu, Load the ExpressLRS LUA script, then you will see the setting menu and bind button on the submenu. 5. Power on your receiver. The LED will blinks twice and then pauses for a while, Then you can bind it with your transmitter. If the LED does not behave like this, please power cycle the receiver three times. 6. After connecting to the transmitterthe LED will be solid, then you can enjoy flying.

Notice: The transmitter and receiver need to maintain the same packet rate, and the flight controller and receiver need to maintain the same protocol. Some serial ports (or UART) of the flight controller have inverters or pull-down resistors may not be suitable for connecting to the receiver.
