Magic RFID Click is a compact add-on board that contains an embedded RFID module. This board features the M6E-NANO, UHF RFID module with ultra-low power consumption from JADAK. Supporting the EPC Gen2V2 and ISO 18000-63 standard, the M6E-NANO module is available for global use. It operates in the Ultra High Frequency (UHF) band in a range from 859 up to 930MHz and can be used for write/read applications. This module provides an output power of +27 dBm, adjustable in 0.01 dB steps with a read speed of 200 tags/sec, meaning that with the appropriate antenna and the configuration of the module itself, greater distances can be achieved (up to 4.5m). This Click board™ is ideal for a wide range of applications in the logistics, security access points, manufacturing, tag commissioning stations, and more.

Magic RFID Click is supported by a mikroSDK compliant library, which includes functions that simplify software development.

Magic RFID Click is based on the M6E-NANO, Ultra High Frequency embedded RFID module with ultra-low power consumption from JADAK. Supporting the EPC Gen2V2 and ISO 18000-63 standard, the M6E-NANO module is available for global use. It can be customized for frequencies in many global regions like the Americas, European Union (EU), India, Korea, Australia, China, and Japan. The ThingMagic‘s M6E-NANO module operates in the UHF band from 859MHz up to 930MHz used for write/read applications. This module provides an output power of +27 dBm, adjustable in 0.01 dB steps with a read speed of 200 tags/sec, meaning that with the appropriate antenna and the configuration of the module itself, greater distances can be achieved (up to 4.5m).

Magic RFID Click supports one monostatic bidirectional RF antenna through edge vias. The maximum RF power delivered to a 50Ω load from each port is 0.5W or +27 dBm. The performance of the module is affected by antenna quality. Antennas that provide a 50Ω match at the operating frequency band perform best. Specified performance is achieved with antennas providing 17dB return loss or better across the operational range. Damage to the module will not occur for any return loss of 1dB. It only may occur if the antenna is disconnected during operation.

The module communicates with MCU using a UART serial port that supports complete functionality except for the lowest power operational mode with a baud rate from 9600 up to 921600bps. Upon initial Power-Up, the default baud rate of 115200 is used. The UART RX and TX lines are buffered with the SN74LVC1T45, a single-bit dual-supply bus transceiver with configurable voltage translation driven by the M6E-NANO Vout pin. This makes the inputs to 5V tolerant and increases the output current driving capability from 10mA to 15mA.

In order to increase the ESD protection, one TVS diode is added to the EN GPIO line. Enable pin labeled as EN, routed on the CS pin of the mikroBUS™ socket, must be pulled HIGH for the module to be operational. When this pin is in a LOW logic state, it turns the module off and reduces its power consumption to nearly zero.

Magic RFID Click possesses a miniature coaxial N.FL series antenna connector, that can be connected to the appropriate antenna.

This Click board™ is designed to operate with both 3.3V and 5V logic voltage levels selected via the VCC SEL jumper. It allows for both 3.3V and 5V capable MCUs to use the UART communication lines properly.
