  1. Good, simple RFID module

    Posted by on

    A nice and simple module with good range for a small antenna.

    The wires from the antenna coil are a little fragile so be careful with them!

    Performs as well as the ID12 that it replaced.

  2. Works Well

    Posted by on

    Works as I'd expect and very happy with it!

    Did find out after playing about that the PCB legends were different to the specs, meaning I had to switch the connections over.
