Has completed the list of columns, details to be continued ...
tool:
Hot melt glue gun, disassemble kit (sheet, screwdriver set), needle nose pliers, tweezers, iron / conditions may be on the hot air gun, selenium welding wire,
Flux, Dupont line / a plurality of connecting lines (the thinner the better but can not softer bare wire), a plurality of heat shrink tubing
First, the modified fuselage (128 million)
BOM
1, APM flight control plate around APM2.8 * 1 120 yuan (with built-in compass) 2.8 looper control built-in compass solo
2, the buck switch module 12V 5V * 1 5 membered 12 5V buck switch module 5V to 3.3V buck module
. 3, 5P 6P 1.25MM cable 10 yuan 10 (also find their places to buy)
4,1117 3.3V regulator transistor * 11 dollars
5, to boot does not require GPS, GPS is bad as you can buy a GPS module GYGPSV3-NEOM8N about 50 yuan * 1
Teardown step, the body is composed of two upper and lower, each surrounded by three snap truck
1, remove the battery, remove the four screws nails, each side of the upper cover is pressed into the body to open
2, look at the three modified battery, a battery interface to determine changing for the better, access should be connected to main positive and negative plate
5V 3,12V transfer module mounted next to the main line access, flight control power to 5V, then INPUT 8; 12V power to the receiver followed by 1117 3.3V
Receiver and several transmission module random placement, the left or the right space
4, APM flight control plate toward the mounting position of the camera head cut, the position in the center, the play may be around, glue gracefully
5, cut four brushless motor linker, then the yellow line Dupont line extended to the APM at OUTPUT, leaving female
6, the receiver (pro mini) wiring, then 2,3,4,5,6,10 mouth of APM 1,2,3,4,5,7
7, the number of transmission lines 5P comparison with FIG wiring connected APM
Second, remote modification (41.5 yuan said adapter plate programs only 15 million)
It is said that there is used a fish adapter plate can be used directly to the receiver, not tested
BOM
. 1, ARDUINO the MINI PRO * 2 10 yuan / block a transmission (remote transmitter), a reception (receiver)
2,24L01 2.4G wireless module * 2 an antenna with 8.25 yuan , one without 3.25 yuan
. 3, the USB to TTL downloader * 13 dollars (may also be made later buy a specific number of transmission)
4, three-stage toggle switches * about 15 dollars for making three-stage control the flight pattern, may be made to buy two control segments 6
5, matrix button, just in what button, but a minimum of five, six or so before and after fine-tuning, a seventh channel store five dollars
Regardless of the original circuit modification step, changing only the line, positive on the motherboard plug left and right negative, the intermediate analog signal
24l01 module connected with PRO MINI
Receiver: MISO (12) MOSI (11) SCK (13) CSN (7) CE (8) VCC (vcc) GND (gnd) IRQ (not connected)
Remote terminal: above the same interface, then need joystick, buttons, toggle switches line
Rocker: four-wire plug, to cut the two intermediate PROMINI of A0, A1, A2, A3
Wheel: on your own, three-wire, cut the middle of the line then A4
Remote playing surface hole, toggle switches mounted on the switch connected to the GND line, respectively, then additional legs A5, A6
Button: All buttons one foot common ground, then the other foot 2,3,4,5,6
Third, the battery refit
Normal boot
Method 1: Buy a plug (copper removed), 6 thimble, and to make a motherboard as an interface module with glue gun, the battery can be directly inserted
Method 2: buy a charger (11 dollars a Po) , remove the used charging interface
Method 3: not recommended, sawed directly on the motherboard power interface
Can not be switched and the battery can not be charged normally
Disassemble the panel is removed, the battery interface may be made directly to the main two thick main column,
No interface, the bore using two thick main lead, and then drilling the black line 4 leads the housing, with the balance rechargeyour
Can not be switched to the battery can be charged
Disassemble the battery, the two main borehole casing using an outer lead
Fourth, data transmission (4 million)
Mainly used for debugging in the air attitude information, can be purchased on a treasure to 10.00 dollars a wireless serial module, a short distance down no problem adjusting parameters
2 dollars a wireless serial port * 2 2.4G, WIFI pass-through did not test, do not know how effective
The first data transmission connection are connected to data transmission module USB to TTL 5V - 5V GND - GND RX - TX TX - RX
Set the baud rate to 57600 (serial port assistant to send AT + 57600)
Module 1 receives the terminal (PC) with a USB cable connected to TTL 5V - 5V GND - GND RX - TX TX - RX
Sending end module 2 (body) and APM TELEM interface 5V - 5V GND - GND RX - TX TX - RX
V. FIG pass (21 million)
A treasure to buy twenty dollars image transmission or hundreds of dollars in phone image transmission line, the effect was almost, the entry can still play
