The module is powered by
single power supply
, use 3.3 V or +5 V
on appropriate pin 13 or 15.
All module inputs are LVTTL and are 5 V tolerant.
Outputs pins with names prefixed by dash character ("-") are active in log. 0,
all other signals are active in log. 1.
All outputs are doubled. Outputs on pins 5 to 8 are with 3.3 V levels and
connect directly ENC28J60. If 5 V power supply is used, signals with 5 V levels
are available on pins 1 to 4. Connect outputs with corresponding voltage level
according to applications need, see the table above.
2.1 Connection to 3.3 V application
If the modules is to be used in 3.3 V application input and output signals of
ENC28J60 are used directly.

2.2 Connection to 5 V application
In case the module is to be used in 5 V application, the output signals are
connected through integrated level converter while input signals are are
connected directly ENC28J60 (which is 5 V tolerant). A 3.3 V voltage regulator
for powering the ENC28J60 is part of the module.
