Product Diagrams

Schematic diagrams for the SuperP 14CH Diversity Receiver 2.4G and 915M/868M versions are provided, illustrating port connections and pinouts.

Port Descriptions and Notes

Note on VBAT: The voltage detector port is set up at VBAT and supports detecting 1~6S battery voltage.

Channel Configuration Notes:

• When configuring CRSF output, CH13 becomes RX, and CH14 becomes TX.
• When configuring SBUS output, CH13 has no output, and CH14 becomes SBUS.
• By default, the receiver's CH11 and CH12 are set for I2C output. In this configuration, CH13 becomes CH11, and CH14 becomes CH12.

Receiver Status RGB Indications

The packet rate corresponds to the RGB indicator color as shown below (visual representation of color spectrum for 2.4G and 915M/868M packet rates).

Packet Rate Modes

2.4G Packet Rates:

• F1000 and F500: Supported under FLRC mode, offering lower latency and faster configuration, but with a shorter receiving distance, suitable for racing.
• D500 and D250: Packet rates under DVDA (Déjà Vu Diversity Aid) mode, working under F1000 rate of FLRC mode. They send multiple identical packets to ensure a safer radio link connection in complex environments. D500 sends packets twice, and D250 sends them four times.
• D50: An exclusive mode for ELRS Team900, sending packets four times repeatedly under 200Hz Lora Mode, with a receiving distance equivalent to 200Hz.
• 100Hz Full: Achieves 16-channel full resolution output at 200Hz packet rates of Lora mode, with a receiving distance equivalent to 200Hz.

915M/868M Packet Rates: (Details similar to 2.4G, with specific modes like D50 and 100Hz Full applicable).

Bind Procedure

The stock firmware for the SuperP 14CH Diversity Receiver is ExpressLRS version 3.3.0, with no pre-set Binding Phrase. Transmitters must use V3.0.0 or above without a binding phrase for binding.

1. Power the receiver on and off 3 times, pausing for 2 seconds between each step to enter binding mode.
2. The receiver's indicator will blink orange twice rapidly, indicating it is in binding mode.
3. Enter the radio or transmitter module's binding mode to bind with the receiver. A solid indicator light signifies successful binding.

Note: Once bound, the receiver remembers the device, and future binding will be automatic.

If the receiver has been flashed with firmware and has a binding phrase set, the above method will not work. Set the same binding phrase on the transmitter module for auto-bind.

It is recommended to separate the two antennas as far as possible for better receiving performance.

Failsafe and Channel Output Mode Setup

When the connection is lost, the failsafe function adjusts all channels to preset failsafe values to maintain device operation and safety. Setting failsafe values is crucial, especially if not using a flight controller.

Channels CH11-14 can be used as PWM output ports or configured as Serial Ports (e.g., CH11/CH12 for SCL/SDA with I2C sensors, CH13/CH14 for CRSF/SBUS with flight controllers).

Configuration Steps:

• Power on the receiver and wait 60 seconds without binding to any equipment.
• The RGB indicator will flash green slowly, indicating the receiver's WiFi has been activated.
• Connect to the WiFi network (Name: ExpressLRS RX, Password: expresslrs) using a cellphone or PC.
• Open the website address http://10.0.0.1 to access the page for failsafe values and channel output setup.

Failsafe Value Setup

Enter the failsafe value (988~2012) for the servo.

Notes:

• Do not use the "invert" flag.
• Values will be halved if the "750us" flag is set.
• If the failsafe value exceeds 1500, the mode will automatically switch to "on/off".

Channel Output Mode Setup

• 50-400Hz: PWM frequency.
• 10KHzDuty: Used to directly drive micro motors.
• ON/OFF: Outputs High or Low power level.
• Serial TX/RX: Serial Port.

CRSF/SBUS Output Setup

1. Set CH 13 to Serial RX or CH14 to Serial TX.
2. In the Serial Protocol setting, select SBUS and click "SAVE".
3. Set the UART baud rate if applicable (not for SBUS).
4. Click "SAVE&REBOOT" to complete the CRSF/SBUS output setup.

Note:

• When using CRSF output, CH13 becomes RX, and CH14 becomes TX.
• When using SBUS output, CH13 has no output, and CH14 becomes SBUS.

I2C Serial Port Setup

I2C serial port settings can be configured via the webpage: http://10.0.0.1/hardware.html. The method is similar to the above.

Procedure:

1. Remove pins 19 and 22 from the PWM output pins.
2. Enter 19 into the SCL pin input box and 22 into the SDA pin input box.
3. Click "SAVE TARGET CONFIGURATION" to complete the I2C serial port setup.

Note: CH11 and CH12 are factory-configured as I2C serial ports. In this setup, CH13 becomes CH11, and CH14 becomes CH12.
