Cov ntaub ntawv xav tau -

(1.) IC - LA4440 x1

(2.) aux cable x1

(3.) Hais lus - 20W x1

(4.) Adapter - 12V

(5.) Jumper hlau

(6.) Capacitor - 25V 100uf x1

Kauj Ruam 2: LA4440 IC

LA 4440 IB
LA 4440 IB

Qhov no yog lub tshuab hluav taws xob IC. Qhov IC no muaj 14 tus pin.

Peb tuaj yeem suav nws cov pins los ntawm sab xub ntiag raws li qhia hauv daim duab.

Kauj ruam 3: Txuas Capacitor

Txuas Capacitor
Txuas Capacitor

Ua ntej peb yuav tsum txuas lub capacitor.

Solder +ve tus pin ntawm lub ntsuas hluav taws xob rau tus pin-1 ntawm IC raws li cov kab laug sab hauv daim duab.

Kauj Ruam 4: Txuas Txuas Txuas Jumper Hlau

Tom ntej Txuas Jumper Hlau

Tom ntej no peb yuav tsum txuas jumper xaim.

Solder jumper hlau rau tus pin-2, tus pin-3, tus pin-8 thiab tus pin-14 ntawm IC li cov laug hauv daim duab.

GND pin-pin-2, pin-3, pin-8 thiab pin-14.

Kauj Ruam 5: Txuas Aux Cable Hlau

Txuas Aux Cable Hlau

Tam sim no txuas aux cable hlau rau hauv Circuit Court.

Txuas sab laug/Txoj cai xaim ntawm aux cable mus rau -ve tus pin ntawm lub capacitor thiab

Txuas -v xaim ntawm aux cable mus rau GND xaim ntawm IC uas yog tus pin-2, tus pin-3, tus pin-8 thiab tus pin-14 raws li koj pom hauv daim duab.

Kauj Ruam 6: Txuas Tus Hais Lus

Txuas Tus Hais Lus
Txuas Tus Hais Lus

Tam sim no peb yuav tsum txuas tus hais lus xaim rau hauv Circuit Court, Solder +ve hlau ntawm tus hais lus rau tus pin-10 thiab

-ve xaim ntawm tus neeg hais lus rau tus pin-12 ntawm IC.

Kauj Ruam 7: Tam sim no Txuas Cov Khoom Siv Hluav Taws Xob

Tam sim no Txuas Cov Khoom Siv Hluav Taws Xob
Tam sim no Txuas Cov Khoom Siv Hluav Taws Xob

Tam sim no peb yuav tsum txuas lub zog xa xov hlau mus rau hauv Circuit.

NCO TSEG: Muab 12V 1-3A DC fais fab mov rau hauv Circuit.

# Txuas +ve cov xov hluav taws xob txuas rau tus pin-11 ntawm IC thiab

# -v xaim hluav taws xob xa mus rau GND xaim li cov laug hauv daim duab.

YUAV TSUM siv nws li cas -

Muab lub hwj chim rau hauv Circuit Court thiab ntsaws aux cable rau lub xov tooj ntawm tes/laptop/tab ……

Txaus siab rau cov nkauj

Yog tias koj xav ua cov phiaj xwm hluav taws xob ntau dua tom qab ntawv ua raws li tam sim no.
