    What is the maximum current this cable can supply through the 5V wire?
    The schematic shows an inductor in series with VBUS which becomes 5V.
    Maybe in the next revision, have another leg of VBUS that connects directly to 5V.

    Why is this board using a NPN transistor in common emitter configuration? With the 10K resistor, this board will only output around 1mA at 12 volts.
    A PNP transistor will allow this board to drive a higher current load (up to the max Ic of the transistor) such as relays and motors.

    When using the Reset line to re-read a transponder, wait at least 200ms after bringing the reset line high, then read, and then bring it back low.

No public wish lists :(
