3.3V-5V VOLTAGE TRANSLATOR
The  3.3V-5V  VOLTAGE TRANSLATOR  additional  board  is  used  to  adjust  voltage  levels  of  a  development  system 
sending voltage signals of 3.3V and a device receiving voltage signals of 5V. 
How to connect the board?
The 3.3V-5V VOLTAGE TRANSLATOR board can be easily connected to a development system via a 2x5 connector 
CN1  and a flat cable  with appropriate  IDC10 connectors,  Figure 1. The board  is connected  to a device  via a 2x5 
connector CN2
.
How to use the board?
The additional board is used to adjust different voltage levels by means of two transceivers 74LVCC3245. The board 
comes with jumpers placed so as to adjust voltage signals of 3.3V to voltage signals of 5V. If necessary, voltage signal 
adjustment may also be performed in the opposite direction (from 5V to 3.3V).
The additional board is powered by 3.3V and 5V. The 3.3V power supply voltage is supplied from the development 
system,  whereas  the  5V  DC  power  supply  voltage  is  supplied  from  an  external  power  supply  source  via  the  CN3 
connector.
