• ELRS X1 flight controller will work with the ELRS 2.4Ghz TX module which was updated V1.0.0 or latest version firmware. So no need to flash old RC3 version firmware for the TX module. Specification：Flight controllerMCU:STM32F411CEU6 (100MHZ, 512K FLASH)Sensor: MPU-6000(SPI connection)Mount pattern: 20x20 M2Power supply: 2-4S Lipo batteryBuilt-in 12A Blheli_s ESC eachBuilt-in Betaflight OSD(SPI Control)Built-in SPI ExpressLRS 2.4GHz receiverBuilt-in 5V 1A BECFlight controller firmware target: CRAZYBEEF4SX1280 Onboard 4in1 ESCMCU upgraded to EFM8BB21Power supply: 2-4S LiPo/LiPo HV (7v/17v)Currents: 12A continuous peak 15A (5 seconds)Support BLHeliSuite programmableFactory firmware: F_H_40_REV16_8.HEXDefault protocol: DSHOT150/DSHOT300/DSHOT600 Onboard SPI ExpressLRS 2.4GHz ReceiverPacket Rate option: 25Hz/50Hz/150Hz/250Hz/500HzRF Frequency: 2.4GHzAntenna plug: IPEXTelemetry output Power: <12dBmReceiver protocol: SPI ExpressLRSCould bind with ELRS 2.4Ghz TX module(Recommend TX module with latest elrs firmware) Onboard voltage and Amperage meters settingsVoltage meter scale setting 110Amperage meter scale setting 470 Bind procedure: Power the flight controller by connecting USB. Please make sure that the port driver of the flight controller is correctly installed on the computer, then open Betaflight Configurator(Latest version) to connect, enter to the "receiver" interface, and then click "Bind Receiver", the red LED at the bottom of the flight controller will flash quickly, which means that the SPI ELRS receiver enters the bind mode. There is another way to make the receiver enter the bind mode: after connecting to the Betaflight configurator, move to the CLI interface and enter "bind_rx" in the command line. After correctly connecting the 2.4G ELRS TX module to your Opentx radio transmitter, copy the latest version of ELRS.LUA file to the SD card in the remote controller. The directory is "SD Card/Scripts/tools", Then run ELRS.LUA and upgrade thefirmwareto latest version and click “bind” with the SPI ELRS receiver. Please make sure the packet rate is the same between the SPI ELRS Receiver and your ELRS TX module. Change packet rate for the SPI Receiver command in the CLI tabSet expresslrs_rate_index = 3Allowed range: 0
• 4Default value: 00=500Hz,1=250Hz,2=150Hz,3=50Hz,4=25Hz After the binding is successful, the Red LED at the bottom of the flight controller will getting to be solid, and the telemetry can be received at the same time. The meaning of the LED status of the SPI receiver: the LED is getting to be solid, indicating that the bind is successful or the connection and communication is normal, the LED flashing quickly indicates that the receiver is in binding mode, and the LED flashing slowly indicates that the there is no signal received from the radio controller.
