FOIRE AUX QUESTIONS - EAX70191101 LG

Comment connecter le lecteur NFC EAX70191101 à un microcontrôleur ?

Le module utilise une interface I2C haut débit. Connectez les broches SDA et SCL à votre microcontrôleur, ainsi que VCC (3,3 V), GND, et éventuellement VEN pour la réinitialisation et IRQ pour les interruptions.

Quels types de tags NFC sont supportés ?

Le lecteur supporte les tags NFC Forum de type 1 à 5, y compris MIFARE Ultralight, Jewel, FeliCa, MIFARE DESFire, et les tags ISO/IEC 15693 (ICODE).

Quelle est la distance de lecture maximale ?

La distance de lecture dépend de l'antenne et de l'environnement, mais elle est typiquement de l'ordre de 2 à 5 cm avec l'antenne PCB intégrée.

Le lecteur fonctionne-t-il avec des smartphones ?

Oui, il peut communiquer avec des smartphones compatibles NFC en mode lecteur/écrivain ou en mode pair à pair (NFCIP).

Comment configurer le mode autonome ?

Le mode autonome est activé par le firmware. Le module peut être configuré pour effectuer des tâches prédéfinies sans intervention de l'hôte, avec réveil automatique via le champ RF, une minuterie interne ou l'interface I2C.

Quelles sont les tensions d'alimentation acceptables ?

La plage de tension d'alimentation est de 3,0 V à 3,6 V (typiquement 3,3 V). Ne pas dépasser ces valeurs.

Le module nécessite-t-il une antenne externe ?

Non, le module intègre une antenne PCB. Vous pouvez toutefois utiliser une antenne externe si vous adaptez le circuit d'accord.

Comment réinitialiser le module ?

Appliquez un niveau bas sur la broche VEN (Reset) pour mettre le module en état d'extinction forcée (Hard Power Down). Un niveau haut le réactive.

Quels sont les protocoles de communication supportés ?

Le module supporte NFCIP-1 et NFCIP-2, ISO/IEC 14443A, FeliCa, MIFARE Classic, et ISO/IEC 15693. Il utilise l'interface NCI pour la communication hôte.

Le module est-il compatible avec Arduino ?

Oui, vous pouvez l'utiliser avec une carte Arduino en connectant les broches I2C (SDA/SCL) et en utilisant une bibliothèque NFC adaptée, comme la bibliothèque Adafruit PN532 (avec modifications pour ce module).
