MikroElektronika Click Manual de usuario

1. Introduction

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.

3. Plugging the board in

2 3

2. Soldering the headers

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

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.

DC Motor click Manual

ver. 1.01

0 100000 025468

DC MOTOR click™is a DC motor driver board

in mikroBUS™form factor. It features the

DRV8833RTY H-Bridge motor driver,

74HC4053 multiplexer and two screw

terminals. DC MOTOR click™communicates

with the target board via SELECT1,

SELECT2 and nSLEEP control lines, PWM

input line and nFAULT feedback line. The

board is designed to use 3.3V or 5V power

supplies. It has a GREEN power supply

indicator LED and a RED LED that indicates

active nFAULT line (in case of short-circuit).

DC MOTOR click™with its DRV8833RTY

IC’s is limited to a 0.9A driving current

with 0.22Ωcurrent sense resistor. The

74HC4053 IC is incorporated into the

design in order to run the motor with only

one PWM line available on the mikroBUS™

socket. Use jumper J2 to select whether you

want to power the board with the on-board

or external power supply connected to the

CN2 screw terminal. The motor should be

connected to the CN1 screw terminal.

Once you have done all the necessary

preparations, it’s time to get your click™board

up and running. We have provided examples

for mikroC™, mikroBasic™and mikroPascal™

compilers on our Libstock website. Just

download them and you are ready to start.

5. DC MOTOR click™Board Schematic 6. SMD Jumpers

There is a single SMD jumper (zero-ohm

resistor) J1 which is used to select between

3.3V or 5V power supplies. By default, it’s

soldered in the 3.3V position.
