This RFID Receiver for Onion Omega makes it easy to interface RFID cards, fobs, tags, and stickers into your next automation application. Simply swipe a RFID device across the sensor and read the code into the Onion Omega at 9600 baud. The OOI2CU includes an integrated I2C port for easy expansion to the entire NCD I2C Product Line. This design includes the popular EM18 RFID receiver, greatly simplifying software development. This product includes a 1 ft cable for remote mounting of the RFID reader. Includes RFID Card and RFID FOB.
What is the I2C Interface?
The supplier of plug and play modular hardware using the I2C Interface connector standard. It allows you to chain together several devices on the I2C bus, and communicate to each device individually at high speed (subject to the limitations of I2C). The I2C Interface uses a standard 4-Pin I2C Input and I2C Output connector. These devices communicate on the power of 5V I2C data and provide 5V DC power through this connector. The advanced embedded devices use standard I2C communications for all data transport, which is supported by nearly every microcontroller in production today. The I2C Interface is strictly a 5V standard, which is ideal for transport across longer cables. The device Package always includes a 6? (152mm) 4-conductor I2C cable. The I2C based Mini Modules always include a 3? (76mm) 4-conductor I2C cable. Cables and connectors are available separately for designers who would like to include their own I2C Interface into their designs.
