MHF1 Reader Module User Manual Revision 0 2 Safety instruction and Warnings Use this documentation to familiarize yourself with all necessary steps and considerations that must be considered before using this device. This device must strictly be used in accordance with the guild lines explain in this documentation and any changes or use of parts and additional devices which is not recommended by the manufacturer may cause harmful injuries and the manufacturer is not liable for such cases. Users must consult with the most recent documentation available at the time of purchase. The manufacturer is not responsible for the use of outdated or unsuitable documentation that may lead to incorrect use of the device. Any modification and/or repairs must be conducted by the manufacturer or its qualified representative. 3 Module Application and Operation Frequency MHF1 module is a RFID-reader module designed for the purpose of reading and encoding passive RFID-tags. MHF1 Module operates at 13.56 MHz and is suitable for applications that require RFID read and write in a short to medium range and can be installed as an embedded module in other devices in combination with a certified antenna. MHF1 Module is encapsulated in an RF shielding that inhibits EM interference. 4 Reader Module and Accessories Table 1 Type Model Number Description Reader Module MHF1 Antenna: external Antenna connector: U.FL and Separate 2 pole Connector Supply: 5 V DC RF shielding: Metal cap I/O: 4 Digital inputs/outputs Serial Interface: TTL Compatible Antenna ANTH100-BL Desktop Antenna Antenna ANTH2 Embedded Antenna Antenna ANTH-SP1 Embedded Antenna Intelletto Technologies Inc. www.intelletto.com Page 3 of 14

MHF1 Reader Module User Manual Revision 0 6 Terminal Connections Figure 2 shows the pin assignment for terminal connections J1 and J2. Both terminals are designed to be used with 0.1” (2.54mm) socket connector or alternatively soldered directly to a PCB with proper footprint. Application of each pin is defined in table 1 and 2. External approved antennas can be used with MHF1 module through a 50 Ω coaxial cable connected to RF receptacle Conn1. Conn1 is an ultra miniature RF connector installed on the PCB under EMI shielding cap. Please see the antenna connection section of this manual for more information on approved antennas and connection to Conn1. Figure 2 Intelletto Technologies Inc. www.intelletto.com Page 5 of 14

Battery input or linear regulators are recommended. In case of using other type of supply such as switching regulators user must ensure minimum ripple by applying adequate filtering to ensure a clean supply to MHF1 module. Dirty supply to the module may reduce the read and write functionalities. MHF1 module does not have any protection for reverse polarity. Wrong connection to power supply may permanently damage the module. Intelletto Technologies Inc. www.intelletto.com Page 6 of 14

MHF1 Reader Module User Manual Revision 0 9 Antenna Connection Following explains available antennas and connection type to MHF1 Module. 9.1 Desktop Antenna ANTH100-BL is a desktop antenna (Figure 4) approved to be used with MHF1 module. ANTH100-BL is designed with a RP SMA Plug connector. See table 6 for the matching cable type to be used with this antenna. Figure 4 9.2 Embedded Antenna ANTH2 is a small antenna designed for embedded application (Figure 5) approved to be used with MHF1 module. Connector type on this antenna is an ultra miniature (U.FL) jack. See table 6 for the matching cable type to be used with this antenna. Figure 5 Intelletto Technologies Inc. www.intelletto.com Page 8 of 14

MHF1 Reader Module User Manual Revision 0 9.3 Embedded Antenna ANTH-SP1 ANTH-SP1 is a medium size antenna designed for embedded applications approved to be used with MHF1 module. This antenna is not available for resale as an individual item but it is being used in other products available from the manufacturer. Table 6 Coaxial Cable Application Picture Ultra miniature R/A plug to To connect MHF1 module RP SMA jack to antenna with RP SMA plug connector Ultra miniature plug to To connect MHF1 module Ultra miniature plug to antenna with U.FL jack Connector 9.4 Antenna Connector on MHF1 MHF1 is designed to connect to one external antenna using connectors CONN1 or J2. Both connectors are connected internally therefore the user may use either of them, but not both at the same time. CONN1 is an ultra miniature RF connector to be used with 50Ω matching plug and coaxial cable. J2 is a 2 pin 0.1” header connector to be used in embedded applications. J2 connector is mounted on the back of the module and it is visible. CONN1 on the hand is not visible and EMI shielding must be removed temporarily to connect to this connector. Figure 6 shows MHF1 module without shielding. Placement of CONN1 is marked on Figure 6 where it shows MHF1 module without EMI shielding. Intelletto Technologies Inc. www.intelletto.com Page 9 of 14

MHF1 Reader Module User Manual Revision 0 Figure 6 10 Using Digital Input and Outputs MHF1 is designed to have four bidirectional digital I/O lines. Default setting of each I/O line is to be an output. Absolute maximum on each I/O lines is 3.3 Volts and 6 milliamp sink or source. For example any of four I/O lines can be configured to light up an LED when a RFID tag is intercepted by the module, see Figure 7. Please note special test firmware must be loaded before using the module in standalone tag sense mode. Figure 7 11 Firmware upgrade Firmware on MHF1 module can be updated through J3, depicted in figure 6. Special tool and cable is required to update the module with new firmware.
