Hello all, I am a high school student from New Jersey.
Last year I purchased a DEV-10406 RFID Evaluation Shield and an SM130 module along with it. I assembled a circuit that interfaced the shield and module to an Arduino Micro and then from the Micro drove an LCD screen. Initially, there were no issues on the hardware or software level. I did NOT solder the SM130 to the board nor used headers. I let the chip sit in the appropriate pin holes. In fact, I have a video that shows the entire breadboard circuit in full operation. I will post a URL later on.
However, when I brought the circuit to school for a presentation, the device didn't work. Normally, when power and the appropriate RX/TX pins are connected, the Shield should have both the Power LED and the Search LED on, but only the Power LED was working. In addition, none of the tags I used were registering.
After some more troubleshooting and suffering a very poor grade (Teacher operates on a binary grading system) I discovered that when held a certain way the Shield worked perfectly and when held in other ways the same problem occurs. This leads me to conclude that it's the pin connections between the sm130 and the RFID Eval shield that are the culprit. I have TWO sets of these components and the SAME problem is occurring.
I have tried soldering the components together, but that didn't work, and now it also made it near impossible to remove the module from the shield afterwards.
The components I used:

https://www.sparkfun.com/products/10406
https://www.sparkfun.com/products/11319

My question is, how do I fix these pin connections on the board? What sort of methods should I use to ensure the ensemble works correctly?
Thanks, Ezra.
