MF RC522 spi sau / nyeem module for Arduino, Rs232 / RS485 interface

RC522 Chip Base
MF RC522 tau thov rau 13.56MHz tiv toj kev sib txuas lus Maintion Engine APP daim npav nyeem ntawv, yog nxp rau lub "Peb lub rooj" Daim Ntawv Thov Tshaj Tawm ntawm tsawg-voltage, Tsawg tus nqi, Qhov loj me thiab daim npav hu tsis pub dawb, Cov cuab yeej ntsuas hluav taws xob ntse thiab Portable Handheld cov cuab yeej tsim tau zoo dua. MF RC522 Siv cov kev hloov pauv thiab demodulation phiaj xwm tag nrho hauv txhua hom ntawm 13.56MHz passive kev sib tham txoj kev sib tham thiab cov txheej txheem. Txhawb Nqa 14443A Tshaj Ntxiv Pitter. Cov digital ntu kho iso144443A Framing thiab Kev Paub Yuam Kev. Ntxiv rau, Txhawb Cov Lus Qhia Ceev Crypto1 encryption, Terminology Siv Tau Cov Khoom Siv Equidation. MFRC522 Txhawb Mifare series siab dua ceev ceev tsis pub sib tham sib txuas lus, Ob-txoj kev hloov cov ntaub ntawv hloov mus txog 424kbit / s. Raws li kev sib koom ua ke heev 13.56MHz Card Nyeem Ntawv Tshiab Tsev Neeg ntawm Chips, MF RC522 MF RC500 thiab MF RC530 thiab muaj ntau yam sib xws, tab sis kuj tseem muaj ntau yam ntxwv thiab qhov sib txawv. Nws yog nruab nrab ntawm tus tswv kev sib txuas lus siv SPI hom, pab txo kev sib txuas, Txo pcb board loj thiab tus nqi.

Cov Ntawv Qhia RFID Module
MF522-ib tug module adopts Philips Mfrc522 Tus Thawj Nyeem Circuit Court Tsim, yooj yim siv, Tus nqi qis, Haum rau cov khoom siv kev txhim kho, Kev txhim kho cov ntawv thov siab heev xws li nyeem cov neeg siv, Qhov xav tau rau RF daim npav davhlau ya nyob / kev tsim khoom ntawm tus neeg siv. Cov qauv no tuaj yeem thauj ncaj qha rau ntau yam ntawm cov nyeem pwm. Module siv hluav taws xob ntawm 3.3V, los ntawm SPI interface cov kab ntawv yooj yim tau yooj yim txuas nrog tus neeg siv txhua CPU Board kev sib txuas lus module tuaj yeem lav thiab ua haujlwm txhim khu kev qha ruaj khov thiab ntseeg tau, Nyeem ntev nrug.
