User Manual
Description
The MR-MINI-LEVEL-SHIFTER is a device
that translate +5V to +3.3V logic or +3.3V to
+5V logic. There are no external
components required. This makes it perfect
for embedded systems that need to interface
with different logic level.
The board features innovations that set it
apart from other level-shifter board.
Innovations feature like on-board +3.3
voltage regulator, jumpers select direction,
male and female input/output terminals and
power on LED. The module can be easy to
interface via male or female headers. The
board is small can compact in size 2.20 x
1.70 inches.
The MR-MINI-LEVEL-SHIFTER is designed
base on 74LCX245 IC. It is eight non-
inverting bidirectional buffers. The device is
designed for low voltage (3.3V) VCC
applications with capability of interfacing to a
5V signal environment.
+3.3V LEVEL SHIFTER
***NOTE***
There is an on-board +3.3V/500mA
regulator provided. User only needs to
supply power to +5.0V pin. +3.3V pin is an
output voltage that can supply up to
500mA. DO NOT attempt to input any
power to this pin. Doing so may damage
the board.
Configurations:
1. Configure the board as +5.0V input
and +3.3V output.
The jumper DIR must be set to
position A-TO-B. Logic +5V logics
are connect to side A as input and
+3.3V logics are connect to side B
as output. Signal logic +5V from
side A is send through buffer and
convert to +3.3V logic on side B.
