A motorized development platform 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.
STEP 1 - Remove wheels from one side STEP 2 - Connect the battery STEP 3 - Insert the battery 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. Pull the battery wire under the rail and attach it to the battery connector. Push the whole battery under the rail. Be careful not to pinch the wire. The battery should fit squarely between Buggy’s four motors.
A motorized development platform STEP 7 - Insert mikroBUS™ socket plates STEP 8 - Solder mikroBUS™ socket plates STEP 9 - Set side panels in place 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. While holding the mikroBUS™ socket plate inside the slit with your finger, flip the Buggy. Solder the plates, making sure to cover each of the eight contact points.

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 different microcontroller architectures.

clicker 2 – a click™ board two-seater Available for several MCU architectures, clicker 2 is a compact development kit with two mikroBUS™ sockets for click™ board connectivity. You can use it to quickly build your own gadgets with unique functionalities and features. It’s an ideal Buggy driver because it lets you leverage the huge potential of click™ boards, our constantly expanding range of over 100 add-on boards.
A motorized development platform Lights Motors VCC-5V D3 PMEG3010ER 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 firmware for the Buggy.
Power supply Battery charger Screw teminals ON/OFF switch 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 off. The Buggy’s expandability is not limited to mikroBUS™ sockets and click™ boards.

click™ boards are plug-and-play! For a few years now, MikroElektronika has been expanding their range of click™ boards. Almost each month several new click™ boards are released, carrying all types of sensors and communication modules. There are over a 100 click™ boards to choose from. You’ll be able to expand your Buggy with additional functionality with literally zero hardware configuration. Just plug and play. For the complete list of available click™ boards, please visit: www.mikroe.
A motorized development platform Firmware Android application If your clicker 2 board came with the Buggy as part of a kit, then you’re all set — the firmware 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 firmware.
