CEEB TOOM
- Cov khoom lag luam no yuav tsum tsuas txuas rau lub zog siv hluav taws xob sab nraud ntawm 5V / 3A DC lossis 5.1V / 3A DC tsawg1. Kev siv hluav taws xob sab nraud uas siv nrog Raspberry Pi 4 Tus Qauv B yuav tsum ua raws li cov cai muaj feem xyuam thiab cov qauv tsim nyog hauv lub tebchaws uas xav siv.
- Cov khoom no yuav tsum ua haujlwm hauv qhov cua zoo thiab, yog siv sab hauv rooj plaub, rooj plaub yuav tsum tsis txhob npog.
- Cov khoom no yuav tsum muab tso rau ntawm qhov chaw ruaj, tiaj, tsis muaj qhov chaw zoo nyob rau hauv kev siv thiab yuav tsum tsis txhob tiv tauj los ntawm cov khoom lag luam.
- Cov kev sib txuas ntawm cov khoom siv tsis raug rau qhov sib txuas ntawm GPIO tej zaum yuav cuam tshuam rau kev ua raws cai thiab ua rau muaj kev puas tsuaj rau lub tsev thiab ua tsis tau raws lub warranty.
- Txhua tus yuam sij siv nrog cov khoom no yuav tsum ua raws li cov qauv tsim nyog rau lub teb chaws siv thiab cim kom raug raws li ntseeg tau tias kev nyab xeeb thiab ua tiav tau raws li qhov xav tau. Cov ntsiab lus no suav nrog tab sis tsis txwv rau cov twj paj nruag, tus saib xyuas thiab nas thaum siv nrog Raspberry Pi.
- Qhov chaw txuas txuas txuas nrog uas tsis suav cov xaim lossis txuas, lub cable lossis txuas txuas yuav tsum muaj cov rwb thaiv tsev txaus thiab kev ua haujlwm kom thiaj li ua tiav cov kev ua tau zoo thiab kev nyab xeeb ua tau.
SAFETY CEEB TOOM
Txhawm rau kom tsis txhob ua haujlwm tsis zoo lossis puas tsuaj rau cov khoom no thov saib raws li hauv qab no:
- Tsis txhob nthuav dav rau dej, noo noo lossis qhov chaw ntawm qhov chaw conductive nto thaum ua haujlwm.
- Tsis txhob nthuav tawm nws kom kub los ntawm txhua qhov; Raspberry Pi 4 Qauv B yog tsim rau kev ua haujlwm txhim khu kev qha ntawm chav ib puag ncig ib puag ncig.
- Saib xyuas kom zoo thaum tswj xyuas kom tsis txhob muaj cov tshuab lossis hluav taws xob ua puas rau cov ntawv luam tawm Circuit Circuit thiab cov txuas.
- Zam tsis txhob kov cov ntawv luam tawm Circuit whilst nws tau siv hluav taws xob thiab tsuas yog tuav los ntawm cov npoo los txo qis txoj kev pheej hmoo ntawm electrostatic kev puas tsuaj.
Ib qho khoom siv zoo 2.5A fais fab fais fab tuaj yeem siv tau yog tias nqes dej USB khoom siv hluav taws xob tsawg dua 500mA nyob rau hauv tag nrho.
