Description
4-In-1 STM32 Multiprotocol TX Module with Case for JR IRX4 Plus 2.4G CC2500 NRF24L01 A7105 CYRF6936
Description:
This 2.4G Multi-protocol TX Module is an STM32 ARM microcontroller-based module. All available protocols are included in serial mode. It is suitable for many brands of quadcopters, helicopters, and airplanes.
This module integrates four RF chips (CC2500, NRF24L01, A7105, CYRF6936) into one single circuit board, it .supports a variety of remote control protocols, such as Futaba S-FHSS, Walkera DEVO, Spektrum DS M2, DS MX, Flysky, Frsk y, WLToys, Hubsan, Hisky, Esky, Assan, etc. You can control your craft flexibility with it, and You will get much excellent experience with your favorite transmitter.
Parameters:
- Item Name: IRX4 Plus
- Operating Voltage: 5-14V
- Operating Current: <=100mA
- Operating Frequency: 2.4G ISM band
- RF Power: +22dBm
- MCU: STM32F103CBT6 (128K ROM, 20K RAM)
Package Included:
- 1 x Multiprotocol TX Module
- 2 x Jumper Caps
Features:
Two operation modes: PPM mode and serial mode.
- When in PPM mode, there are 31 different protocols (protocol NO.0 is reserved for serial mode) mapping to the 16-position protocol selection switch on the module. They are listed in the default protocols table below, when the green light is off, you can use the switch to choose protocol NO. 1 to NO.15, when the green light is on, you can choose protocol NO.16 to NO.31.
- To turn on/off the green light, please follow these steps:
Turn off your transmitter, point the protocol switch to ‘0’, hold and press the bind button of the RF module, then turn on your transmitter, after 3 seconds, release the button.
Normal Use Operation in PPM Mode:
1. Install RF Module in position, Set PPM signal output on your transmitter.
2. According to the default protocols table, turn the arrow sign (the side with a vertical slot) of the protocol switch to the proper number to choose the protocol.
3. After finishing the binding operation, Power on your transmitter, the red light of the RF module will be on, then the RF module is ready to work, and after that power on your receiver (or craft).
4. Protocol selection is done at the beginning of power up, so if you want to change protocol during operation, you should recycle the power.
5. The red light will blink slowly if there is no valid PPM signal.
Binding Operation in PPM Mode:
1. Power on your receiver, and set it to binding mode.
2. Hold and press the bind button of the RF module, and then turn on your transmitter, after 3 seconds, release the button, and you will see the red light flashing rapidly, the RF module is in binding mode, and the red light will go solid after binding.
3. Some protocols (eg: S-FHSS) don’t have the binding procedures on the RF module, and some protocols (eg: hubsan, e010)will auto bind when powered up.
Operation in Serial Mode:
When the green light is off, and the protocol switch is pointed to ‘0’, you can access serial mode. A transmitter that supports the er9X/erSky9X or Open TX firmware can work in this mode, The model protocol selection and binding are done from the Model Settings menu on the transmitter, For telemetry capable transmitters, the telemetry integration is done seamlessly with the transmitter firmware.

About the Firmware Upgraded:
Two jumper caps are included. Do not short-circuit during normal use. When upgrading the firmware, you need to short-circuit according to the situation.
The tuner can be upgraded in two ways: USB serial cable or Micro USB cable (also known as the Android phone data cable). The USB serial port mode is relatively simple, so some users generally need a USB serial cable to upgrade.
