Nyob zoo sawv daws.

Peb txhua tus muaj cov roj teeb LiPo seem/khaws cia, uas peb tau rov qab los ntawm cov roj teeb laptop qub lossis yuav cov roj teeb tshiab.

Txhawm rau siv lawv peb txhua tus siv cov khoom lag luam muaj rau kev them nqi, tiv thaiv thiab txhawb qhov hluav taws xob mus rau 5V rau siv lawv los txhawb peb cov cuab yeej USB xws li them xov tooj, them nyiaj hauv txhab nyiaj, them Bluetooth lub mloog pob ntseg thiab hais lus, khiav arduino thiab Esp8266-NodeMCU cov laug cam thiab lwm yam khoom.

Tab sis cov laug cam no sib cais thiab xav tau cais cov thaiv thiab nws lub sijhawm thiab qhov chaw siv.

Yog li, hnub no peb yuav tsim qauv, tsim thiab tsim All-in-One LiPo roj teeb them nrog kev tiv thaiv Circuit Court thiab 5-Volt txhawb lub rooj tsav xwm.

Kauj Ruam 2: PCB Txheej Txheem thiab Tsim

Kuv tau siv EasyEda los tsim 2-txheej PCB.

Nws yog qhov yooj yim thiab lom zem siv thiab muaj cov tsev qiv ntawv hneev taw ntawm feem ntau ntawm cov khoom siv.

Yog leej twg xav tau kuv tuaj yeem tshaj tawm cov ntaub ntawv gerber rau koj.

Kauj Ruam 3: Kev xaj cov PCBs

Tam sim no peb tau txais PCB tsim thiab nws yog lub sijhawm los xaj cov PCB. Txog qhov ntawd, koj tsuas yog yuav tsum mus rau JLCPCB.com, thiab nyem rau ntawm "QUOTE NOW" khawm.

JLCPCB kuj yog tus txhawb nqa txoj haujlwm no. JLCPCB (Shenzhen JLC Electronics Co., Ltd.), yog lub tuam txhab PCB loj tshaj plaws hauv Suav teb thiab cov tuam txhab tsim khoom lag luam tshwj xeeb tshwj xeeb hauv PCB sai sai thiab tsim PCB me me. Koj tuaj yeem xaj yam tsawg kawg ntawm 5 PCBs rau tsuas yog $ 2. Txhawm rau kom tau txais PCB tsim, xa cov ntaub ntawv gerber koj rub tawm hauv cov kauj ruam kawg. Rub tawm cov ntawv.zip lossis koj tseem tuaj yeem rub thiab poob cov ntaub ntawv gerber. Tom qab xa cov ntawv zip, koj yuav pom cov lus ua tiav hauv qab yog tias cov ntawv tau ua tiav tiav. Koj tuaj yeem tshuaj xyuas PCB hauv Gerber tus saib kom paub tseeb tias txhua yam zoo. Koj tuaj yeem saib ob sab saum toj thiab hauv qab ntawm PCB. Tom qab ua kom ntseeg tau tias PCB zoo, tam sim no koj tuaj yeem tso qhov kev txiav txim ntawm tus nqi tsim nyog. Koj tuaj yeem xaj 5 PCBs rau tsuas yog $ 2 ntxiv rau kev xa khoom. Txhawm rau txiav txim, nyem rau ntawm "SAVE TO CART" khawm. Kuv cov PCBs tau siv 2 hnub los tsim khoom thiab tuaj txog hauv 20 hnub siv tus qauv sau npe xa khoom xa tuaj. Muaj cov kev xaiv xa khoom sai kuj muaj. PCBs tau ntim tau zoo thiab qhov zoo yog qhov zoo tiag tiag.

JLCPCB tam sim no muab cov kev pabcuam SMT sib dhos uas ib yam nkaus ntawm tus nqi tsim nyog thiab tom qab sim nws Kuv yuav tsum hais tias lawv ua haujlwm tau zoo thiab lawv cov khoom siv tes ua yog piv rau lwm qhov lag luam PCB tsim thiab sib dhos ua haujlwm thoob plaws ntiaj teb.

Lawv pab pawg backend tau txais txiaj ntsig zoo thiab dhau los uas lawv yuav tshuaj xyuas txhua tus thiab txhua qhov kev tsim thiab cov khoom tso rau thiab yuav qhia rau cov neeg siv khoom txog qhov yuav tsum tau hloov pauv hauv kev tsim lossis hais txog kev tso tsis raug thiab tsis sib xws ntawm cov khoom thiab kho qhov teeb meem me me ntawm lawv tus kheej kawg.

Kauj Ruam 4: Sib dhos thiab Ua Haujlwm

• R2 thiab R4 resistor tsim cov lus tawm tswv yim rau lub zog txhawb zog thiab tau suav los muab 5V
• L1 yog 1206 SMD kev hloov pauv, nws zoo dua los siv lub zog hluav taws xob kom tau txais cov zis ntau dua tam sim no, muaj cov khoom seem rau tib yam
• LEDR (RED) yog rau them tus nqi taw qhia
• LEDG (GREEN) yog rau them qhov ua tiav
• Cov tswv yim tam sim no tam sim no rau TP4056 yuav tsum yog 1-1.5 Amps li saum toj no uas IC tau kub heev thiab muaj kev pheej hmoo ua rau nws puas tsuaj. Kuj tseem yog nws txoj kab hloov pauv IC ntau dua tam sim no ntawm qhov hluav taws xob ntau dua txhais tau tias lub zog poob ntau dua li cua sov thiab txo qhov ua tau zoo tag nrho
• Ntxiv VBUS thiab GND1 tus poj niam lub taub hau rau txuas xov hlau ncaj qha hloov chaw MicroUSB chaw nres nkoj
• Toggle hloov tswj cov zis ntawm 5-Volt cov dav hlau
• Qhov no yog hla-lub charger thiab yog li yuav muab lub zog rau 5-V lub davhlau ya nyob twg txawm tias thaum them nyiaj
