Attention:
Power supply must be well regulated, stable and free of noise.
Note
:
1)
For Legic modules, only antenna pins ANT1 & ANT2 need to be connected.
Mifare modules have all 4 ANT pins connected.
2)
After power-up, all inputs are 'OFF', thus on +5V over a pull-up resitors; and
the outputs are not active, thus on +5V.
3)
Clock&Data versions of the µOEM module output the decimal converted card
number.
