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
Rotary R click™with its LED ring is a perfect
solution for implementing an input knob into
your design (in contrast to a potentiometer,
a rotary encoder can be spun round
continuously). A single rotation is divided into
15 discrete steps. The encoder outputs A and
B signals (out of phase to each other). The
knob is also a push-button outputted through
the interrupt line. The LED ring are controlled
through the SPI interface.

Rotary R click™carries a 15-pulse incremen-
tal rotary encoder with detents, surrounded
by a ring of 16 red LEDs. It communicates
with the target board through mikroBUS™
SPI lines (CS, SCK, MISO, MOSI), and three
additional lines for outputting the Encoder
info: ENCB OUT, ENCA OUT and SW (in
place of the standard AN, RST and INT pins,
respectively). Rotary R click™can be used
with either a 3.3V or 5V power supply.
