MIFARE Classic Read/Write Module, TTL/Wiegand 34/RS232: overview
The HF-180 is a single-protocol 13.56 MHz module for products that only need ISO/IEC 14443A cards, such as MIFARE Classic 1K/4K access and membership cards. It returns the UID of MIFARE Classic, Ultralight and NTAG2xx cards and can read and write data held in MIFARE Classic sectors, which suits stored-value, locker-assignment or visitor-pass schemes that keep data on the card.
The antenna is integrated on the 38 × 29 mm board, and rated read distance is up to 60 mm depending on the card and surroundings. By default the module runs in automatic card-search mode and pushes card data to the host as soon as a card is presented, so a simple controller can listen without polling.
Three output builds share one footprint: TTL UART for microcontroller hosts, Wiegand 34 for access controllers, and RS232 for PCs, kiosks and older terminals. Demo software and an SDK are supplied for development.
Integration notes
Connection is a 6-pin, 2.54 mm pitch header: reset, a reserved input, D1, D0, ground and power in. D1 and D0 carry serial RX/TX on the serial builds and Wiegand DATA1/DATA0 on the Wiegand build. Serial speed is set by command between 9600 and 115200 bit/s, defaulting to 115200. The ordering table lists all three builds at 5 V; the datasheet also names 3.3 V as a supply option, so confirm the voltage when you order. Current draw is below 100 mA, and the module is rated –10 to +70 °C.

HF-180 FAQ
Can the HF-180 write to cards?
Yes. Besides reading UIDs, it reads and writes MIFARE Classic sector data. Ultralight and NTAG2xx cards are listed for UID reading.
Which Wiegand format does the Wiegand build output?
HF-180-M-W34 outputs Wiegand 34 on the D0/D1 pins. If your controller expects Wiegand 26, look at the HF-160-M-W26 or HF-170-M-W26.
Does the host need to poll for cards?
No. The default mode is automatic card search, so the module sends card data as soon as a card enters the field. Serial builds run at 9600–115200 bit/s, 115200 by default.
What supply voltage does it use?
The listed builds run at 5 V DC ±5% and draw under 100 mA. The datasheet also lists 3.3 V as an option; confirm it at order if your host rail is 3.3 V only.
