5. Main Features: NFC emulation, APDU commands

Hardware

DL512 NFC module has a USB interface and integrates both MCU (ATmega32U) and NFC IC (PN512) in a single board, distinguishing it from other Arduino-based solutions on the market which require the use of an external NFC reader mounted as an Arduino shield.

DL512 NFC module ensures dependable and optimal NFC interactions, further enriched by the capability to run Arduino code natively. This presents users with an Arduino-centric device enhanced with NFC functionalities.

This NFC module’s RF communication is based on its robust, highly integrated NXP IC interface. The device operates on HF 13.56 MHz and works with cards, labels, wristbands, and tags of ISO/IEC 14443 A, ISO/IEC 14443 B, and ISO/IEC 18092 standards:

• MIFARE Mini®,
• MIFARE Classic® (1K, 4K, EV1),
• MIFARE Ultralight®,
• MIFARE Ultralight C®,
• MIFARE Plus® (2K, 4K, S, X, EV1),
• MIFARE DESFire® (Light, 2K, 4K, 8K, EV1, EV2),
• NXP NTAG® 21x (210, 213, 215, 216, Tag Tamper),
• NXP NTAG® 4xx DNA (413, 424),
• NXP JCOP® Java Card (J3A040, J3A081, J3H145, JC30M48CR).
• Jewel
• FeliCa 

The integrated PN512 IC also supports NFC card emulation and full Peer-to-Peer functionality.

Library and Software SDK

To use the device, an RFID library is essential. We've adapted the well-known MFRC-522 RFID Reader library* and released the MFRC522_PN512 library to be compatible with the PN512 chip. You can access the PN512 library via the Arduino Library Manager within the Arduino IDE or directly from our GitHub at https://github.com/nfc-rfid-reader-sdk/MFRC522_PN512/.
For more information about compatibility with other Arduino boards visit: https://www.arduino.cc/reference/en/libraries/mfrc522_pn512/

Currently available software examples:
GetCardInfo - Reading basic information of an NFC card, such as: card type, card UID and card SAK. Displaying information in the serial monitor
GetCardUID - Reading card UID. Displaying information in the serial monitor.
LEDCard - Green LED flashing while the NFC card is in the RF field.
SendCardInfoToUSB - Reading basic information of an NFC card, such as card type, card UID, and card SAK. Keyboard emulation functionality.
SendCardUIDToUSB - Reading card UID. Keyboard emulation functionality.
