mikroElektronika 4-20mA R click User manual

1. Introduction
Once you have soldered the headers your
board is ready to be placed into desired
mikroBUS™ socket. Make sure to align the
cut in the lower-right part of the board
with the markings on the silkscreen at the
mikroBUS™ socket. If all of the pins are
aligned correctly, push the board all
the way into the socket.

4. Essential features
Turn the board upward again. Make sure
to align the headers so that they are
perpendicular to the board, then solder the
pins carefully.
Turn the board upside down so that
bottom side is facing you upwards. Place
shorter parts of the header pins in both
soldering pad locations.

Before using your click board™, make sure
to solder 1x8 male headers to both left
and right side of the board. Two 1x8 male
headers are included with the board in
the package.

4-20mA R click Manual
ver. 1.01
0 100000 023242
4-20mA R Click™ is an accessory board in
mikroBUS™form factor. It’s a compact and
easy solution for adding 4-to-20mA industry
standard communication protocol to your
design. It features INA196 current shunt
monitor, MCP3201 12-bit ADC as well as
TPS61041 DC/DC boost converter. 4-20mA
R Click™ communicates with target board
microcontroller via mikroBUS™SPI (SDO,
SCK, CS) and EN lines. The board is designed
to use 3.3V and 5V power supply. LED diode
indicates the presence of power supply.
4-20mA R
4-20mA R Click™ board is ideal for using in
eld of industrial process control and test
systems. The board serves as receiver in
4-20mA current loop standard. It receives
output current (4-20mA) from transmitter
and convert into a voltage (0.4-2V). Then
through the AD converter sends signal to
main board microcontroller. This board and
the 4-20mA T Click™ board together form a
complete 4-to-20mA current loop standard.

6. SMD Jumper
There is one zero-ohm SMD jumper J1 used
to select whether 3.3V or 5V power supply is
used. Jumper J1 is soldered in 3.3V position by
default.
