BusIO Push Button Switch Input BOARD
User Manual
Description
The MR-BusIO-SW is an experiment
board for receiving input from push button
switch. When the switch has been
pressed, the indicator LED is illuminated
and status on I/O pin is LOW. Moreover,
user can add DS18S20 IC, 1-Wire Digital
Thermometer onto the board. It can send
the temperature value via 1-Wire bus
system to microcontroller (optional). It is
best
for
sensing
switch
input
and
temperature reading.
The board can be use with MR-BusIO-
MAIN board or stand-alone. PCB size is
0.63” x 2.80”
Operation:
There are three ways to use this board:
As a switch input: When user press the
switch, logic LOW is apply at the I/O pin.
The indicator LED is also illuminated. I/O
pin read logic HIGH when the switch is
de-press.
As a VR (Variable Resistor): This is
optional. User has to solder 10 POT on to
the board. It’s operating as a voltage
divider of VCC.
As an 1-Wire Thermometer (DS18S20):
This is optional. User has to solder 3-PIN
DS18S20 on to the board, pin1 GND, pin2
DQ, and pin3 VCC. The 1-Wire data can
be read from an I/O pin.
Do not connect
VR when using this option.
