The Roadrunner is a Loco positioning compatible tag that combines the hardware of a Crazyflie with the UWB positioning of the Loco products in a handy package. It's ready for mounting on 3rd party robots and supports power supplies up to 12V. It can communicate through cable connection or via radio.

For more information on the Loco Positioning System please see this Loco Positioning System page.

Specifications are based on the standard 2-way ranging mode.
