Pineapple 2 model aircraft remote control receiving board

3Receive motherboard

The Pineapple 2 receiver still adopts the classic design layout, 2.54mm-16P pin header *3 ,

Red and blue dual LED indicators, frequency linking button, 1.25mm-2P horizontal mounting interface *4 , wireless module

Use the back patch button. The design integrates a serial signal bus output interface ( PPM/SBUS ),

This interface is a SIGN interface, and the output signal is from the remote control [Output] - [Serial Bus] menu

set up. At the same time, two level output interfaces are integrated: OUT1/OUT2 . The OUT1 output interface is composed of

CH15 channel switch control, OUT2 output interface is controlled by CH16 channel switch, OUT1/OUT2

The interface can be controlled by an external electronic switch module. The BAT interface is a battery voltage detection interface that supports

2-8S lithium battery ( 0-36V ) voltage measurement. Pineapple 2 receiver uses A32-S433A20S1a

Zeyao Technology wireless module, under the technical application of PLTX-PL2 system and LoRa spread spectrum modulation,

The communication distance is significantly improved. By connecting the suction cup antenna / long glue stick antenna, it has

Advantages of high penetration.

3.3 Peripheral configuration

3.3.1 Power supply

The Pineapple 2 receiver pin header uses 5V/6V/9V BEC power input, and the yellow pin header is the signal

No. 1 wire, the red pin is the positive wire of the power supply, and the blue pin is the negative wire of the power supply.

Note: The receiver must be powered by BEC power input! Do not use batteries to directly power

Electricity will cause unstable work! If the ESC does not have a BEC , you need to use an external UBEC to

Receiver power supply. Do not use voltages that are too low or too high! Do not connect the pin header connector backwards, otherwise it will

Cause the receiver to directly heat and burn!

3.3.2 Rudder signal output

The Pineapple 2 receiver adopts signal synchronization output mode, steering volume + level + PPM/SBUS simultaneously

output. Supports all 16 channels of standard 1-2ms rudder signal output.

3.3.3 Battery voltage detection

The BAT interface on the Pineapple 2 receiver motherboard is a battery voltage detection interface, supporting 2-8S ( 0-36V )

The power battery voltage is detected and sent back to the remote control.

3.3.4 Level signal output

The Pineapple 2 receiver adopts signal synchronization output mode, steering volume + level + PPM/SBUS simultaneously

output. Supports level signal output and can be connected to electronic switch modules.

3.3.5 Serial bus signal output

The Pineapple 2 receiver adopts signal synchronization output mode, steering volume + level + PPM/SBUS simultaneously

output. The serial bus SIGN interface can output PPM/SBUS serial bus signals, which can be controlled by the remote control.

Settings, support 8 -channel PPM signal output and 16- channel SBUS signal output. Output

The PPM signal is a positive logic signal, and the SBUS signal is a negative logic signal.

4.1Menu button

The Pineapple 2 remote control has only two menu control buttons: KEY1 and KEY2 , which simplifies the hardware

Difficulty. KEY1 controls the menu entry / return menu function. KEY2 controls entering the menu directory /

Switch interface / switch menu row settings / fine-tune switching functions. KEY1/KEY2 menu button integration

Various operations are provided, and users can perform skilled operations according to voice prompts.

4.2 Rotary encoder

The Pineapple 2 remote control uses a rotary encoder. In the picture, the position of KEY3 is the rotary encoder.

It is a digital potentiometer, divided into clockwise forward / counterclockwise reverse / press operations. turn spin

The encoder controls menu up and down / menu addition and subtraction / independent fine-tuning. Pressing the rotary encoder is

KEY3 function, switching confirmation operation between menu up and down / menu plus and minus / independent fine-tuning functions.

4.3 Interface switching

After the Pineapple 2 remote control is turned on, it will enter the main interface display screen. In the main interface (above picture)

Under the display, press the [ KEY2 ] button and the main interface will switch to the switching screen display (picture below).

Implement the switching function between the main interface display and the switching interface display.

The difference between the main interface display and the switching interface display is that the rotating wheel is displayed in the main interface state.

The status of buttons KN1-KN4 and switches SW1-SW8 . In the switching interface status, the receiving

The voltage returned by the machine, the received signal strength returned by the receiver, and the opening status of the mixing control MIX1-MIX8 .

The user can switch between these two different parameter display screens by pressing the [ KEY2 ] button.

Change the display function. Among them, the throttle lock and out-of-control warning (receiver return signal disconnection) are small.

Icons can pop up in both interfaces to make it easier for users to know.
