M5Stack RFID2 13.56MHz sensor module with HY2.0 cable for Arduino and UIFlow IoT development

This RFID2 unit from M5Stack provides a dedicated 13.56MHz RFID sensor in a compact module format, designed for prototyping and Internet of Things applications. It comes complete with a HY2.0-4P cable for immediate connection to compatible hosts. The module supports development on popular platforms like Arduino and UIFlow, the latter allowing programming through Blockly or Python. With its specific protocol support and practical mounting features, it offers a focused solution for integrating RFID reading capabilities into custom projects without requiring extensive additional components or setup.

Features and Construction

The RFID2 module is built around the WS1850S sensor, operating at 13.56MHz. Its construction centres on providing reliable RFID communication for prototype and educational use, with physical design choices that aid integration.

Material and Build

The module consists of electronic components assembled on a standard PCB. The inclusion of two Lego-compatible mounting holes on the unit allows for secure physical attachment to structures or prototype enclosures using common Lego-compatible building systems, aiding in stable project assembly. The design prioritises functional connectivity and mounting over aesthetic casing.

Size and Practical Fit

The module has a compact footprint, measuring 7 by 2 units. This size makes it suitable for incorporation into space-conscious prototypes and IoT devices. The operating temperature range is specified from -20°C to 85°C, indicating it is designed for standard indoor environments and should not be exposed to conditions outside this range. The provided reading distance is less than 20mm, defining it as a short-range, close-proximity reader.

Uses and Placement

This module is intended for projects requiring RFID identification or data transfer. Its application field is explicitly stated as the Internet of Things, covering a wide range of connected device scenarios.

Event or Professional Use

In professional or event contexts, such as access control prototypes, inventory tracking systems, or interactive exhibits, this module can serve as the RFID sensing component. Its support for common protocols like ISO14443A, MIFARE, and NTAG means it can read a variety of compatible tags used in such systems. The 64-byte transceiver buffer handles data packets for these applications.

Everyday Home Use

For hobbyists, educators, or home automation enthusiasts, this module enables the creation of custom RFID-based projects. Examples include a smart lock prototype, a personal inventory logger, or an interactive toy. The compatibility with Arduino and the visual UIFlow platform (using Blockly or Python) lowers the barrier to entry for users with different programming experience levels.

Benefits and Buying Value

The value of this module lies in its integration-ready format and specific feature set for RFID development, avoiding the need to source and connect individual sensor components.

Reuse and Low Maintenance

The module is a solid-state electronic component with no moving parts, suggesting low physical maintenance. The stated data storage capability of the system it integrates with is over 10 years. The module itself is designed for integration into a larger project, where its reuse would involve reprogramming the host controller for different applications rather than modifying the sensor hardware.

Why Choose This Product

This module is a suitable choice for developers seeking a ready-to-use 13.56MHz RFID sensor that includes the necessary cable and supports major prototyping platforms. The concrete differentiators are its explicit Arduino/UIFlow support, the included HY2.0-4P cable, the Lego-compatible mounting holes, and its focused protocol compatibility. It provides a specific set of tools for a developer to add RFID functionality without sourcing a separate sensor, cable, and designing a mounting solution.
