I want to install RFID system as a car Security system. The PCB has on built coil and works fine with 5 leads attached to Arduino. Due to its bigger size, i cant place it in the required position. I have therefore decided to cut the coil part of PCB to make the coil small and place it in the required area.
- Can I do that or Can I connect any external coil with it ?
- How to reduce the no. of pins to max 2 or 3.
Thanks
