MF RC522 SPI Rubuta / Karanta Module for Arduino, RS232 / RS485 Interface

RC522 guntu Gabatarwa
MF RC522 ne amfani da 13.56MHz contactless sadarwar sosai hadedde guntu katin karatu, ne NXP ga "uku Tables" aikace-aikace kaddamar da wani low-ƙarfin lantarki, maras tsada, kananan size da kuma wadanda ba lamba katin karatu guntu, mai kaifin instrumentation kuma šaukuwa na hannu da na'urorin ɓullo da mafi alhẽri zabi. MF RC522 amfani da m daidaitowa da demodulation ra'ayi gaba hadedde a duk iri 13.56MHz m contactless sadarwa da hanyoyin da ladabi. Support 14443A jituwa transponder sakonni. A dijital kashi iyawa ISO14443A siffatawa da kuskure ganewa. Bugu da kari, goyi bayan azumi CRYPTO1 boye-boye Algorithms, terminology Ingancin Mifare kayayyakin. MFRC522 goyon bayan Mifare Series mafi girma gudun maras lamba sadarwa, biyu-hanyar canja wurin bayanai rates har zuwa 424kbit / s. A matsayin mai matuƙar hadedde 13.56MHz katin karatu sabon iyali na kwakwalwan kwamfuta, MF RC522 MF RC500 da MF RC530 kuma akwai da yawa kamance, amma kuma suna da abubuwa da yawa da kuma bambance-bambance. Shi ne tsakanin rundunar sadarwa ta amfani da SPI yanayin, taimaka wajen rage dangane, rage PCB hukumar size da kuma kudin.

RFID module Gabatarwa
MF522-AN module rungumi dabi'ar Philips MFRC522 asali karatu kewaye guntu zane, sauki don amfani, maras tsada, dace da kayan aiki ci gaba, ci gaba na ci-gaba da aikace-aikace da irin wannan karatu da masu amfani, da bukatar RF katin m zane / samar da mai amfani. Wannan module za a iya ɗora Kwatancen kai tsaye a cikin wani iri-iri masu karatu kyawon tsayuwa. Module yana amfani da ƙarfin lantarki na 3.3V, ta hanyar da SPI dubawa sauki 'yan Lines za a iya kai tsaye haɗa da mai amfani da wani CPU hukumar sadarwa module iya tabbatar da barga ne kuma abin dogara aiki, karanta dogon nesa.
