A motorized development platform
Introduction
For years we have been honing our expertise in designing powerful and easy to use hardware development tools. Our reputation was forged, in part, on our range of mikromedia boards and the ever-growing line of click
boards. This time,
we’ve put all that experience to use, and put it on wheels —
the Buggy is a four-wheel robotics workstation that takes advantage of all the innovations we came up with in recent years: it employs a clicker 2 / mikromedia pinout that makes it compatible with a wide range of microcontroller architectures. Then we added mikroBUS
sockets giving
you the choice of over 100 click
boards to enhance the
four-wheeler and make it your own with various sensors and
communication boards. We also published a free Android App for remotely controlling the Buggy and we made the code available to you. Finally, we took great care to provide you with the relevant documentation to make it easy to start working on your Buggy projects right away. Hence this manual. Enjoy.

Assembly
With basic soldering skills you’ll assemble the Buggy in no time. Check out the “package contains” section on page 7 to make sure you have everything prepared. Then proceed with step 1 and all the way through.
11
STEP 1 - Remove wheels from one side
The Buggy’s main board is packed in the box with wheels attached. Remove both wheels from the left side of the board, by pulling on them.
STEP 4 - Insert battery holder tabs
Look for the two smallest pieces of PCB in the box. Those are the supporting tabs that keep the battery in place. Pick either one and place it in the sockets on either side of the board, so that the curved side is facing outwards
STEP 2 - Connect the battery
Pull the battery wire under the rail and attach it to the battery connector.
STEP 5 - Solder battery holder tabs
Hold the battery-holder tab and ip the
main board so that the battery is now facing downwards. Solder the tab. Repeat step 4 and 5 for the second battery-holder tab.
STEP 3 - Insert the battery
Push the whole battery under the rail. Be careful not
to pinch the wire. The battery should t squarely
between Buggy’s four motors.
STEP 6 - Reattach the wheels
The axle and the socket on the wheel are not completely round, so be careful to correctly align them before pushing the wheel towards the axle.

STEP 7 - Insert mikroBUS™ socket plates
The Buggy comes with three additional mikroBUS
socket plates. Pick either one and slip it inside one of the three slits on the main board, marked mikroBUS 1, mikroBUS 2, and mikroBUS 3.
STEP 10 - Attach top bar
The top bar connects the two side panels and keeps the Buggy rigid, while also providing slots for soldering additional electronics. Notice that each
side panel has four dierent slots for placing the
top bar. You can use whichever one suits you best.
STEP 8 - Solder mikroBUS™ socket plates
While holding the mikroBUS™ socket plate inside
the slit with your nger, ip the Buggy. Solder
the plates, making sure to cover each of the eight contact points. Repeat steps 7 and 8 for the remaining two plates.
STEP 11 - Solder top bar
Solder the top bar to each side panel. You can always unsolder it later if you’d like to to change its position.
STEP 9 - Set side panels in place
Next, position the two side panels. You won’t be soldering them yet, but pay attention to place the panels in the correct direction: the lower part faces forward, where the white and yellow LEDs are.
STEP 12 - Solder side panels
With the top bar soldered, ip the Buggy. Solder
the two side panels to the main board; there are two contact points for each panel, one in each
corner of the main board. Now ip the Buggy back
on its wheels. You’re done assembling!

Choose your driver
Now that you’ve assembled the Buggy, the only remaining thing is to put a microcontroller in the driver’s seat. You have two types of choices: (1) clicker 2 is a compact development platform with a MCU and two mikroBUS
sockets (2) mikromedia is a multimedia development system with a 320x240 TFT touchscreen and
a rich set of onboard modules. Both of these boards are available for dierent microcontroller architectures.
If you want to remotely control your Buggy, you’ll also need a communications click
board with a wireless transceiver module (Wi-Fi or Bluetooth work well).

REAR LEFT LIGHTS
The Buggy has a dierential motor drive. The four DC motors
are split by left and right axis (controlled by DRV833RTY motor drivers, U6 and U7, one for each side). Steering takes place when you vary the relative rate of rotation between the left and right side. This type of steering is simpler to manipulate if you’ll be
writing your own rmware for the Buggy. Also, when one pair
of wheels is put in reverse while the other is in normal gear, the Buggy will start to spin, which wouldn’t be possible otherwise.
Just like a real car, the Buggy has a set of front and rear lights for signaling and for lighting the way. These lights are routed in a way that makes them easier to program should you develop your own
rmware for the Buggy. They’re grouped
in three sets based on function: (1) The pair of white LEDs on the front are headlights, with two modes of brightness; (2) The red LED brake lights on the rear also have two brightness levels; and (3) the two pair of yellow LED signal lights are grouped by left and right side. Pins for controling Buggy’s light
LED schematics
Highlighted above are the ve pins that
control the lights. TURN L and TURN R regulate the signal lights. H.LAMPS turns on the headlights and rear lights at low intensity. Activate both the M.BEAM and
H.LAMPS at the same time for brighter headlights. For brighter rear lights (stop lights), activate the BRAKE and H.LAMPS at the same time.
To prevent the motors from drawing too much current from the battery (and in doing so prevent the other components from functioning properly) a few resistors are placed to limit current draw. Each motor can draw a maximum of 400 mA, for a total of
1.6 A for all four motors.

Power supply
Battery charger
The Buggy runs on a 3.7V 2000mA battery. Once you install the battery, there’s no need to take it out; charge it through the Buggy’s USB port. A miniature single-cell, fully integrated Li­Ion, Li-Polymer charge management controller. MCP73832 enables that. A red power indication LED will signalize when the battery is charging.
Once charged, it’ll turn o.
ON/OFF switch
The ON/OFF switch on the rear of the Buggy, between the USB port and the left rear lights, controls the main power supply. A clicker 2 board also has its own ON/OFF switch, which should be kept in the ON position in order for the main power supply switch to work. A green LED will indicate the presence of a power supply. When removing the clicker 2, keep both switches OFF.
Screw teminals
The Buggy’s expandability is not limited to mikroBUS
sockets and click™ boards. You can attach a variety of sensors and antennas to its top bar. A pair of screw terminals will allow you to connect those additional components to the main power supply. Both 3.3V and 5V outputs are available. There’s an additional pair of screw terminals that are analog inputs.

A motorized development platform
mikroBUS™ sockets
Enhancing the Buggy with various sensors and communication modules is easy — you just plug a MikroElektronika click
board into one of the 3+2
available mikroBUS
sockets and you’re good to go.
mikroBUS
is a specially designed pinout standard with SPI, I2C, Analog,
UART, Interrupt, PWM, Reset and Power supply pins. It has two 1x8 headers, each with VCC and GND power supply pads.
The Buggy comes with three mikroBUS
sockets, two in the front, one in
the rear. If you connect a clicker 2 board to the Buggy you’ll get two more
sockets for a total o ve mikroBUS
sockets.
There are more than a 100 click
boards available. Each click™ board comes
with a single module, and these vary from sensors to displays, audio to motor control, communication to ber optics, even speech recognition. Learn more about the mikroBUS
standard at www.mikroe.com/mikrobus

Firmware Android application
A free open-source Android App for driving the Buggy is available from mikroe.com/buggy. The App talks to the Buggy through a wireless transceiver click
board (Bluetooth or Wi-Fi). It’s a great starting point to develop your own original applications for the Buggy, just open the project in your Android SDK of choice (for example Android Studio, shown
here). But rst, spend some time driving the Buggy
around from your smartphone or tablet, just for fun.
Install the app on your smartphone or tablet and take your Buggy to the road
If your clicker 2 board came with the Buggy as
part of a kit, then you’re all set — the rmware
compatible with the Android app shown on the right is already installed.
If you’ve purchased only the Buggy by itself, no problem. Clicker 2 and mikromedia boards have a USB-HID bootloader which makes it easy to install
the rmware. All you have to do is download the
mikroBootloader application for your clicker 2 or
mikromedia board, along with the rmware, all
available from www.mikroe.com/buggy.
Then turn o the Buggy, detach the clicker 2
board, plug it to your computer via USB, and follow the simple 4-step procedure in mikroBootloader.
If you’re making your own custom rmware for the
Buggy in mikroC
, mikroBasic™ or mikroPascal™,
you’ll also upload it with the mikroBootloader.
