Seeed Studio 113020006 Near Field Communication Wireless Module is a short-range wireless technology device functioning at 13.56 MHz, widely used in industrial and commercial applications such as access control systems and mobile payment solutions.
The module integrates the PN532 transceiver, which handles reliable contactless communication protocols. Users can perform tag reading and writing operations or implement data exchange between two NFC modules for versatile communication needs.
Designed for interfacing with microcontrollers or embedded hosts via I2C or UART protocols, the module defaults to UART for ease of integration. The dedicated PCB antenna extends outside enclosures to maximize communication range without compromising product design flexibility.
The operating voltage is specified at 3.3V, with a static current consumption of 73mA and an increased 83mA during active write/read operations. Detection range for NFC tags is up to 28 mm, depending on antenna size, which allows effective operation in various system configurations.
This compact module, with dimensions of 25.43 mm by 20.35 mm, is suitable for developers and engineers designing embedded communication devices requiring NFC capabilities for industrial, manufacturing, security, and commercial access control environments.
Features highly integrated PN532 transceiver module for contactless communication. Supports reading and writing of 13.56 MHz tags and point to point data exchange between NFC modules. Communication interfaces include I2C and UART, with UART as the default.
Equipped with an independent PCB antenna for flexible enclosure design. Operates at 3.3V with static current of 73mA and write/read mode current of 83mA. Maximum detection distance for NFC tags is approximately 28mm depending on antenna size.
Supports peer-to-peer communication functionality. Compact dimensions of 25.43mm x 20.35mm suitable for embedded applications.
This NFC wireless module is ideal for use in industrial automation, security systems, manufacturing, commercial access controls, and mobile payment infrastructure. Its compact size and multiple interface support make it a versatile choice for embedded system developers.
