Circuit Board Tester for RFID

Simple one button test for a quick, instant test result.

A circuit board tester to verify if the production board is functional.

Circuit Board Tester


This is a custom circuit board tester for RFID board. Operator simply place the PCB board onto the placement jig and start the testing. The tester can auto detect the board and proceed testing the RFID board.

RFID Circuit Board Tester Description


This test is easily powered up with a USB-C cable detect to support the testing of the RFID Reader circuit board.

There are two ways to test the board. Either by using the spring loaded contact pins, or using the 6 ways JST ZH cable.

The picture on the left provides a basic description of the tester’s device.

RFID Reader Circuit Board

RFID Reader Circuit Board

The RFID Reader circuit board reads RFID tags.

Communication is using I2C through a JST ZH flat cable (6pos, 1.5mm pitch) to a controller board.


The tester is programmed to read only Mifare Classic tags. For RFID Tag, you can use the following RFID tags.

  • Mifare Mini S20 (320 bytes)
  • Mifare S50 (1 Kbytes)
  • Mifare S70 (4 Kbytes)

Physical Dimension of RFID Reader Circuit Board

The board is small at about 40 x 43mm. It has 4x mount hole size at ΓΈ3.2mm for M3 screw mounting. One of its corner is chambered as a marker to ensure that the board orientation is correct when position itself onto the tester device.

Testing Procedure for RFID Reader

  1. Power up the tester using the USB-C cable.
  2. Place the RFID Reader circuit board onto the tester.
    Take note of the corner marker for the correct board orientation. Press the board slightly with finger to ensure that the 6x spring load pins get contact with the RFID reader board.
  3. Using another finger, press in the TEST push button.
  4. The tester will first detect the presence of circuit board.
  5. The tester will then test to check if the reader circuit board is able to test read a RFID tag. Remember to present a RFID tag on top of the RFID reader board.
  6. The RFID tag ID is displayed for verification if it can be detected by the RFID Reader.
  7. Test is PASSED.

Finger pressing slight to ensure that the board is engaged to the tester via the spring loaded test pins.

Video Demonstration 1 – Successful Testing Procedure

Click the video to playback.

The video demonstrates the complete process of testing the RFID Reader circuit board.

Video Demonstration 2 – No RFID Tag Detected

Click the video to playback.

The video demonstrates the same process but without any RFID tag presence. The board is detected and test is passed.

Video Demonstration 3 – No RFID Reader Board Detected

Click the video to playback.

This is a negative demonstration. The tester could not detect the board or if the board is faulty. Board fail to be detected.

Alternate way of testing the board using flat cable.

If testing through spring loaded test pins is tiring, you can test the board using the JST flat cable instead.

Using this method, you do not need to apply constant force to hold the board during the testing process.

The same procedure applies, except that the connection is now via the flat cable instead of the spring loaded test pins.
