Tutorial of Ethernet Based UHF RFID Reader

soliddigi

??In this tutorial, we are going to build Ethernet based UHF RFID reader.
The hardware includes the following:

   

• TTL UART UHF RFID reader module?   
  
• Spruce Board   
  
• UHF RFID antenna
  

The following is a system picture:

?
The jump wire connection is as follows:
1. Spruce GPIO pin 40 -> UHF RFID GND
2. Spruce GPIO pin 14 -> UHF RFID RX
3. Spruce GPIO pin 15 -> UHF RFID TX.
?
The Ethernet firmware that is loaded to the spruce board can be downloaded?here.
The TCP IP test tool can be downloaded?here.

The following is a screen shot of using TCP to read the tag:
