Pineapple 2 model aircraft remote control motherboard

1 Introduction

Pineapple's 2022 new product Pineapple 2 series is newly launched: PL2TX/ Pineapple 2 remote control,

PL2RX/ Pineapple 2 receiver. Pineapple 2 remote control is the fourth remote control developed by Pineapple Technology.

It is also the second 433MHz remote control released . The smoothness of the pineapple PL-TX control system,

Simplicity, ease of operation, etc. have made it used in the Pineapple 8 series and Pineapple 1 series. same,

The Pineapple 2 series also uses the PLTX-PL2 adapted operating system. First used in Pineapple 2 series

LoRa spread spectrum modulation long-distance wireless communication, using the SX1278 wireless module, communication channel

Divided into 433M frequency band ( 410MHz ~ 447MHz ) / 470M frequency band ( 448MHz ~ 485MHz ),

It has CAD channel activity detection technology, transparent transmission address verification and anti-interference technology, etc., which is different from traditional

Compared to the NRF24L01 wireless module with GFSK modulation of 2.4GHz , LoRa spread spectrum modulation of 433MHz

The SX1278 wireless module has long-distance communication, high penetration, and anti-interference. Pineapple

The 2 series is designed by combining the Pineapple 1 series and the Pineapple 8 series, simplifying the motherboard circuit hardware.

It is difficult to install and designed using low-cost components. High-speed rotary encoder operation of Pineapple 2 remote control

And LoRa spread spectrum modulation technology complements each other even more in the control of PL-TX system.

This manual only explains some important aspects. For other menu settings, please refer to the group

The document "Pineapple 8 Series User Manual" is consistent with its operation.

Welcome to join the pineapple remote control production exchange group: QQ877083951 .

2 remote control motherboard

The Pineapple 2 remote control motherboard adopts a simple design, which simplifies the circuit difficulty.

According to the requirements, a double-layer motherboard design is adopted. Users need to solder Zeyao Technology on the front of the motherboard by themselves.

A32-S433A20S1a wireless module and DY-SV17F voice module. The back of the motherboard can be soldered

Jinyichen Electronics 19264 LCD screen, or use a connecting cable to connect. If the screen is directly soldered to the main

A female header can be placed on the board on the right side of the screen. The motherboard uses 2S/3S ( 7.4V/11.1V )

Lithium battery power supply, battery capacity requirement ≥ 1500mah, battery discharge rate requirement ≥ 5C , due to

The motherboard's current jump is high at the moment of voice triggering, so be sure to use high-quality batteries for power supply.

electricity. There are POW , KEY1-2 , EC11 , SPK , CH1-4 , KN1-4 , SW1-8 , PPM ,

TTL interface, all use 2.54mm pin header, need to use 2P/3P/4P/5P conjoined

2.54mm DuPont wire connection, be careful not to use a single DuPont wire connection, otherwise it is easy to cause

The impact of loose interface! Users can make their own motherboards or purchase a group leader kit.

The motherboard wiring sequence is marked with silk screen: [V] Positive power supply, [S] Signal wire, [G] Ground wire!

2.3 Peripheral configuration

2.3.1 Powered by battery

The POW interface on the mainboard of the Pineapple 2 remote control uses 2-3S lithium batteries for power supply.

The capacity requirement is greater than or equal to 1500mah , and the discharge rate requirement is greater than or equal to 5C .

Since the Pineapple 2 remote control motherboard does not have a soft shutdown design, the motherboard POW power interface

A hardware toggle switch needs to be connected in series to turn on the control power supply.

Among them, the 2S battery voltage range is [ 7.2V ~ 8.4V ].

Among them, the 3S battery voltage range is [ 10.8V ~ 12.6V ].

The battery level of the remote control will be displayed according to the battery type selected.

2S battery＜7.2V triggers low voltage alarm,

3S battery < 10.8V triggers low voltage alarm.

Note: The hardware toggle switch should be connected in series to the positive [+] line of the power supply!

Note: The power supply battery must be a 2S/3S lithium battery! Using 1S lithium battery to power the motherboard will

Won't work! Using 4S lithium battery to power the motherboard will burn out! Power supply [+][-] positive and negative poles are not

It can be connected reversely. Reversely connecting the power supply may cause the motherboard to be directly burned!
