Simultaneous RFID Tag Reader Hookup Guide
The SparkFun M6E Nano Simultaneous RFID Tag Reader (SRTR for short) has numerous features that make it a huge leap forward over other RFID readers.
The greatest feature is that the SRTR is able to read multiple tags at the same time. Additionally the read distance of tags is greatly increased (up to 16 feet!) from other readers. Did we mention you can write your own data to the tags? Oh yea, you can do that too.
The SRTR was designed to work either with a USB to Serial connection to a computer or as a shield to an Arduino-compatible board. If you’re just getting started we recommend you start with the serial connection to a computer so that you can use the Universal Reader Assistant software to experiment quickly with different tags and read distances. Then move to a microcontroller or single board computer. You may not need everything though depending on what you have. Add it to your cart, read through the guide, and adjust the cart as necessary.
USB to Serial Connection
For a basic set-up using the SRTR with a USB-to-Serial connection, we recommend the following products.
USB micro-B Cable - 6 FootCAB-10215
SparkFun Serial Basic Breakout - CH340GDEV-14050
Break Away Male Headers - Right AnglePRT-00553
Arduino Shield Connection
If you’re using the SRTR as a shield, we recommend the following materials.
Arduino Stackable Header Kit - R3PRT-11417
Any microcontroller or single board computer capable of 115200bps will work (however the module can be configured to 9600bps). The SparkFun RedBoard or Arduino Uno are popular options for this role, but just about any microcontroller development board should work. (The firmware examples use an Arduino library, if that serves as any extra motivation to use an Arduino.) You will want an external power supply to run the module at full power. Please see the Power Supply Considerations section for more information.
To follow along with the examples in this tutorial, you will also want access to some UHF passive RFID tags, and optionally, an antenna for extended range, and an attachment cable.
