1. Introduction
LightHz Click is an accessory board in
mikroBus™
form factor. Board features
TSL230BR
programmable light-to-frequency
converter. The output can be either a pulse
train or a square wave (50% duty cycle)
with frequency directly proportional to light
intensity. Device sensitivity and frequency
scaling can be determined by the MCU, or
selected using available SMD jumpers if used
in hardware selection configuration. Solder
PWR SEL
SMD jumper to 5V position if used
with 5V systems.
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 the pins are aligned
correctly, push the board all the way
into the socket.

and

selection
of the sensor can be set by
bringing the logic combination to
S0
–
S3
lines
according to sensor specification. This can
be done by soldering
corresponding
SMD
jumpers to appropriate
logic voltage levels, or
they can be connected
to your MCU and
determined by software. Board comes with
SMD jumpers which are set to
ON-BOARD
configuration of scaling and sensitivity. If you
want those lines to be available to your MCU,
just resolder SMD jumpers to
MCU
position.
Default on-board configuration for scaling
is
(S2, S3) = (H, H),
and for sensitivity is
(S0, S1) = (H, H)
.
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 the
both soldering pad locations.

Before using your click board, make sure
to solder the provided 1x8 male headers
to both sides of the board. Two 1x8 male
headers are included with the board in
the package.
