Connecting to the App

We suggest using a smartphone or a tablet to control. Follow those easy steps to connect Chassis to your device:

  1. Download Totem App available on the Google Play or IOS App Store.


  1. Connect the power cable (see the schematics). The lights on the board will indicate the battery charge level.


  1. Two running lights show that Board is waiting for your device to connect.


  1. Open the Totem App and press “Connect” button. A sound and one running light indicate that you have successfully connected to the Board.

  1. Make sure to fully charge the battery for your longer play. Simply connect the Battery to the USB Charger and plug it into any USB Charging device (like PC or your Smartphone charger).

That was it, have fun!


Upgrading Ideas


  • Totem Pre-Cut Maker Kit – perfect addition to build on top of the chassis;
  • Totem Maker Kit – perfect for building larger car projects;
  • Add Servo or other motors up to 0.5 A (not included in the Kit) for more complex and fun projects;
  • Use hot glue or double-sided tape to attach motors to anything. Build from cardboard, use old toy or even 3D print your own idea.
