Bullet Points

  • Featuring 14 PWM channels, this receiver is suitable for different applications. It can drive up to 14 servos, allowing for more complex and precise control. In addition, an external sensor such as a barometer, current sensor, etc, is also supported.
  • A true diversity receiver with two complete RF receiver chains (referring to dual SX1280/SX1281 or dual SX1276), based on the latest official ExprssLRS. It comes with ExpressLRS V3.3 firmware.
  • Built in a TCXO (temperature-compensated crystal oscillator), it is shared by two RF chips for a super accurate clock source. It can withstand extreme temperatures with no fear of heat and cold, continuously outputting accurate frequency for long-range flight.
  • Two antennas will create an omnidirectional signal for good signal transmission. Placing the antenna separately and vertically to get a better signal is recommended.
  • With the support of the failsafe function, it is capable of protecting RC models from being out of control.
  • Reserving a Type-C USB port, it is convenient for pilots to flash the firmware. The plug-and-play design makes it very easy and friendly to use.
  • The 900MHz radio system exhibits greater diffraction ability due to its lower frequency, while the 2.4GHz systems tend to be directional and susceptible to attenuation caused by buildings, foliage, or moisture.

Know More About the TCXO

SuperP 14CH Diversity Receiver is built-in a TCXO (temperature compensated crystal oscillator), which is shared by two RF chips for a super accurate clock source. The true diversity receiver including two RF chips and PA+LNA will generate a large amount of heat when working. With the high-quality TCXO, it can withstand extreme temperatures with no fear of heat and cold, continuously outputting accurate frequency for long-range flight. Click to learn more about the TCXO.

The diagram for SuperP 14CH Diversity Receiver is below.

RGB status indication for SuperP 14CH Diversity Receiver is shown below.

RGB Color Status Description
Rainbow Fade effect Power on
Green Slow flash WIFI upgrading mode
Red Quick flash No RF chip detected
Orange Double flash Binding mode
Orange Triple flash Connected, but mismatched model-match configuration
Orange Slow flash Waiting for connection
Solid on Connected and color indicates packet rate

The below picture shows the RGB light color for the 2.4GHz version corresponding to the packet rate.

The below picture shows the RGB light color for the 915MHz and 868MHz versions corresponding to the packet rate.

Note: F1000 and F500 are packet rates in FLRC mode, providing faster modulation and lower latency, but at the same time having shorter reception distance than normal Lora mode. This mode is great for racers.

D500 and D250 are packet rates in DVDA (Deja Vu Diversity Aid) mode. This mode works at the F1000 data packet rate of FLRC mode, providing better link connection in the case of complex interference by sending the same data packet multiple times. D500 and D250 indicate that the same data packet is sent twice and four times respectively.

D50 is an exclusive mode under ELRS 900M. It will send packets four times repeatedly under 200Hz Lora Mode. Its receiving distance is equivalent to 200Hz.

100Hz Full is the mode that can achieve 16-channel full resolution output at the 200Hz packet rates of Lora mode. Its receiving distance is equivalent to 200Hz.

Port Configuration

Enter the configuration page via WiFi mode.

  • Power on the receiver and wait for 60 seconds without binding to any transmitted equipment;
  • Once the RGB indicator is in slow green flashing, the receiver’s WiFi has been activated;
  • Connect WiFi via cellphone or PC (WiFi name: ExpressLRS RX, password: ExpressLRS) ;
  • Open the website address:

On the configuration page, users can set the PWM pin, CRSF pin, I2C pin, etc. The pin number corresponds to specified channels. You can refer to the chip I/O function table.

Note: Please do not modify other function pins.

Pin 13 15 2  0 4 9 10 5
Main CH1 CH2 CH3 CH4 CH5 CH6 CH7 CH8
Pin 18 23 19 22 3 1 21 36
Main CH9 CH10 CH11 CH12 CH13 CH14 RGB VBAT
Third SBUS

Note: VBAT is the battery voltage detection port, which supports 1~6S battery voltage detection.

When the RX is configured to use CRSF output, CH13 becomes RX and CH14 becomes TX.

When the RX is configured to use SBUS output, CH13 has no output, and CH14 becomes SBUS.

The CH11 and CH12 of the receiver have been configured as I2C serial ports by factory default. At this time, CH13 becomes CH11, and CH14 becomes CH12. 

For example, I2C communication serial port settings are as follows:

  • Delete 19 and 22 in the PWM output pin
  • Put 19 and 22 into the SCL and SDA pin of the I2C
  • Click “SAVE TARGET CONFIGURATION” to complete the setting of the I2C communication serial port

Note: The CH11 and CH12 of the receiver have been configured as I2C serial ports by factory default. Then CH13 becomes CH11, and CH14 becomes CH12.

Binding Procedure

The default firmware of the SuperP 14CH Diversity Receiver uses the ExpressLRS V3.3.0 protocol and has no preset binding phrase. Therefore, the firmware version of the transmitter module must be ExpressLRS V3.0.0 or later versions. Both the receiver and transmitter module should not have any binding phrase.

  • Power on and off the receiver 3 times, each step pausing 2 seconds to enter binding mode;
  • When the indicator starts fast blink with orange twice, the receiving is at binding mode;
  • Enter the radio or transmitter module’s binding mode to bind with the receiver; if the Indicator has turned solid, it indicates that the device has been bound successfully.

Note: After the device has been successfully bound, the receiver will record the device, and future binding will be automatic. There would be no need to go through the binding process again.

Failsafe and Channel Output Settings

The setting method is as follows:

  • After the receiver is powered on, wait for 60 seconds without connecting the remote control
  • The RGB indicator enters the green slow flashing state, and the receiver automatically turns on WiFi (WiFi name: ExpressLRS RX, WiFi password: ExpressLRS)
  • Use a mobile phone or computer to connect to WiFi, and log in to with a browser to find the model page

Failsafe settings are as follows: The output value of the servo can be obtained when the out-of-control protection value is inputted and the system goes out of control.

Note: Do not click “Reverse”. If you click the “750us”, the failsafe value needs to be halved. When the failsafe value is greater than 1500, the mode will automatically switch to “On/Off” mode.

Channel output settings are as follows: Select the desired mode from the dropdown menu of the mode, and the following are descriptions of all output modes.

  • 50-400Hz: output PWM signal frequency
  • 10KHzDuty: used to directly drive micro-motors
  • ON/OFF: output high-level or low level
  • Serial TX/RX: Serial communication port

CRSF/SBUS output settings are specified below:

  • Set the mode of channel 13 to serial RX or set the mode of channel 14 to Serial TX
  • Select the serial port protocol in Serial Protocol, and click “SAVE” to save the settings
  • Set the baud rate on the options page (the SBUS serial protocol cannot set the baud rate)
  • Click “SAVE&REBOOT” to complete the setting of the CRSF/SBUS output

Note: When the receiver is configured to use CRSF output, CH13 becomes RX and CH14 becomes TX; When the receiver is configured to use SBUS output, CH13 has no output, and CH14 becomes SBUS.
