2. Soldering the headers
1. Introduction
3. Plugging the board in
Once you have soldered the headers your
board is ready to be placed into the 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 the pins
are aligned correctly, push the
board all the way into the socket.
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
the bottom side is facing you upwards.
Place shorter pins of the header into the
appropriate soldering pads.
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. Essential features
1
With UV click
™
, you can measure ultraviolet
light intensity both indoors and outdoors.
The photodiode on the ML8511 IC is
sensitive to UV-A (365–315 nm) and UV-B
(315-280 nm) rays. You can use UV click
™
to design devices that protect the user
against excesive sun exposure, or for
industrial purposes where UV light is used
for sterilization. When using UV click
™
, be
careful not to rub or press the surface of
the ML8511 IC.
UV click
™
UV click
™
is a simple solution for adding
an ultraviolet light sensor to your design.
It carries the ML8511 IC UV sensor with
analog voltage output and a MCP3201 ADC.
UV click
™
can output either analog or digital
signals (determined by the position of the
A/D SEL jumper). Therefore, it communicates
with the target board either through
mikroBUS
™
SPI (CS, SCK, MISO), or AN lines;
additionally, the sensor can be enabled or
disabled from the MCU through the RST (EN)
pin. UV click
™
uses a 3.3V power supply.
