Ultra-Thin 1.9 mm 13.56 MHz RFID Module, 3.3 V TTL: overview

The HF-150 is a low-profile 13.56 MHz module for device designers with almost no height to spare. The board measures 47.7 × 25 mm and only 1.9 mm thick with its antenna integrated, and it runs from 3.3 V at under 100 mA, which suits the power rails and space budgets of tablets, handheld terminals and thin wall-mounted devices.

Three builds cover different card estates. The -MV build returns UIDs from MIFARE Classic 1K/4K, Ultralight, NTAG, FM11RF08 and FM1208 cards as well as ICODE (ISO/IEC 15693) tags and DESFire cards. The -MA build covers ISO/IEC 14443A cards up to FM1208 CPU cards, and the -AB build reads MIFARE Classic, Ultralight, NTAG and FM11RF08 UIDs with ISO/IEC 14443 Type B protocol support added. All three talk to the host over a 3.3 V TTL UART.

Rated read distance is 0–30 mm, so the module is intended for deliberate tap-to-identify steps such as member check-in, staff log-on or asset lookup rather than hands-free reading.

Integration notes

The 15-position J14 connection on 2.54 mm pitch carries VCC, ground, UART RXD/TXD, an external interrupt input (INT), SDA/SCL lines and an enable (EN) pin; several positions are unused. UART speed is configurable by command from 9600 to 115200 bit/s (default 115200). The datasheet names USB as an optional interface, but every listed build is TTL. Operating temperature is –10 to +50 °C, so check the thermal budget inside sealed handhelds. Demo software and an SDK are available.

HF-150 FAQ

How thin is the HF-150?

The module is 1.9 mm thick on a 47.7 × 25 mm footprint (±1 mm tolerance), with the antenna integrated on the board.

Can it run from 5 V?

No. It is specified for 3.3 V DC ±5% only, drawing under 100 mA. For 5 V hosts, see the HF-160 or HF-170 families.

Which build reads DESFire and ICODE?

HF-150-MV-T returns UIDs of DESFire cards and ICODE (ISO/IEC 15693) tags in addition to MIFARE Classic, Ultralight, NTAG, FM11RF08 and FM1208 cards.

Is a USB version available?

USB appears as an optional interface in the datasheet, but every current build is 3.3 V TTL. Ask us if you need USB in this footprint.

What temperature range does it support?

Operating –10 to +50 °C and storage –20 to +65 °C, at 15–90% RH.
