The module is powered by single power supply, use either +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.

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.
