This RFID Receiver for Pycom WiPy2/LoPy 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 WiPy2/LoPy at 9600 baud. The LoPyU 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 6″ (152mm) cable for remote mounting of the RFID reader. The I2C port 5V is controlled by a GPIO pin and can be turned on all the time depending on jumper selection. If you are using this with a battery then you can turn on and off the I2C port according to your needs. Includes RFID Card and RFID FOB. I2C connections: GPIO13(SCL)/GPIO12(SDA) Includes RFID Card and RFID FOB.
nodeLynk™ Master Adapter
This is a nodeLynk Master adapter. nodeLynk Master adapters speak to a chain of nodeLynk devices using I2C communications.
What is nodeLynk?
Chain expansion devices using nodeLynk. Connect a wide variety of accessories to expand the capabilities of a nodeLynk compatible controller. Use nodeLynk to add Relay Controllers, Sensors, PWM Drivers, Displays, and a wide variety of 4-20mA, 0-10V ADCs and DACs, as well as a wide array of TTL & Isolated GPIO devices. All nodeLynk devices use I2C communications to chain devices together. nodeLynk is an easy way to expand functionality without soldering. nodeLynk allows expansion in seconds so you can focus on your software and firmware development.
