2. Soldering the headers

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.

4x4 Key

click

4. Essential features

The design of

4x4 Key click

— inputs are read

by a pair of connected 8-bit parallel-in serial-

out shift registers — allows for multiple key

presses at the same time. You can press all

16 buttons simultaneously and each will be

registered. For ease of use, each button has

silkscreen markings. The right-most column

is marked with letters A-D, the other 12

buttons are marked like a telephone keypad.

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.

Turn the board upward again. Make sure

to align the headers so that they are

perpendicular to the board, then solder the

pins carefully.

1. Introduction

4x4 Key click

carries a 16 button keypad

with two shift registers, allowing you to

connect a keypad to a microcontroller

without using too many I/Os.

4x4 Key click

communicates with the target board MCU

through

mikroBUS

™

SPI pins (CS, SCK,

MISO, MOSI). The board is designed to use

either a 3.3V or 5V power supply.

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.
