MF RC522 SPI lembani / werengani module ya Ardino, RS232 / RS485 mawonekedwe

Chithunzi cha RC522
MF RC522 imagwiritsidwa ntchito pa kulumikizana kwa 13.56MHz popanda kulumikizana kophatikizika kwambiri, ndi NXP kwa "Matebulo Atatu" kukhazikitsa kwa low-voltage, mtengo wotsika, yaing'ono kukula ndi sanali kukhudzana khadi wowerenga Chip, zida zanzeru ndi zida zonyamula m'manja zidapanga chisankho chabwinoko. MF RC522 pogwiritsa ntchito kusinthika kwapamwamba ndi lingaliro lachidziwitso lophatikizidwa kwathunthu mumitundu yonse ya 13.56MHz njira zoyankhulirana zopanda kulumikizana ndi ma protocol. Thandizani 14443A zizindikiro zofananira za transponder. Gawo la digito limagwira ISO14443A kupanga ndi kuzindikira zolakwika. Kuphatikiza apo, thandizirani ma aligorivimu achangu a CRYPTO1, terminology kutsimikizika Mifare products. MFRC522 imathandizira Mifare Series yothamanga kwambiri osalumikizana, njira ziwiri zosinthira deta mpaka 424kbit/s. Monga ophatikizika kwambiri a 13.56MHz owerenga makadi banja latsopano la tchipisi, MF RC522 MF RC500 ndi MF RC530 ndipo pali zofanana zambiri, koma alinso ndi zinthu zambiri komanso zosiyana. Zili pakati pa kuyankhulana kwa alendo pogwiritsa ntchito SPI mode, zimathandizira kuchepetsa kulumikizana, kuchepetsa PCB bolodi kukula ndi mtengo.

RFID module Chiyambi
MF522-AN gawo utengera Philips MFRC522 choyambirira owerenga dera chip kapangidwe, Yosavuta kugwiritsa ntchito, mtengo wotsika, oyenera zipangizo chitukuko, chitukuko cha patsogolo ntchito owerenga owerenga, kufunika kwa RF card terminal design / kupanga kwa wogwiritsa ntchito. Gawoli likhoza kuyikidwa mwachindunji mumitundu yosiyanasiyana ya owerenga. Module imagwiritsa ntchito voteji ya 3.3V, kudzera mu mawonekedwe a SPI mizere yosavuta yochepa imatha kulumikizidwa mwachindunji kwa wogwiritsa ntchito gawo lililonse lolumikizirana la CPU board lingatsimikizire ntchito yokhazikika komanso yodalirika., Werengani mtunda wautali.
