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.

Light Click is an accessory board in
mikroBUS form factor. It’s a compact
and easy solution for adding light sensor
to your design. It features PD15-22C-
TR8 PIN photodiode, MAX6106 voltage
reference and MCP3201 ADC with SPI
interface. Light Click communicates
with the target board microcontroller via
mikroBUSSPI (MISO, SCK, CS) and AN
lines. The board is designed to use 3.3V
and 5V power supply. LED diode (GREEN)
indicates the presence of power supply.
Light click
Light Click™ with it’s PD15-22C-TR8 and
MCP3201 ICs is a high photosensitive
light sensor with fast response time. The
board is capable of measuring ambient light
intensity and provides a signal (analog or
digital) to the main board microcontroller.
All these features make this board ideal for
high speed photo detector, copier, game
machine and many more.

6. SMD Jumpers
The Light Click™ board
communicates with the
main board microcontroller
via I2C interface (ADC)
or directly through the analog pin (AN)
depending on the position of the J2 SMD
jumper (ADC position by default). There is
one zero-ohm SMD jumper J1 used to select
whether 3.3V or 5V power supply will be
used. (3.3V position by default).
