Cardbot is a open source robotics project desinged to bring low costs entry level robots to students and kids. This project was started by the non-profit Makr Group (aka Makr) to bring robotics to under served communities in Omaha, Nebraska, USA. With the goal to kickstart intrest in technology and robotics. The Project is ongoing and slowly growing with the capbilites of the robots.

Questions

How big is the Cardbot Controller PCB?

It measures 95 × 27 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Cardbot Controller use?

6 parts, built around the TL1105BF160Q. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Cardbot Controller KiCad files?

From the makr-group/cardbot repository on GitHub, at the commit this page was made from: the board is Cardbot Controller/PCB Files/Cardbot Controller/Cardbot Controller.kicad_pcb and its schematic Cardbot Controller/PCB Files/Cardbot Controller/Cardbot Controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Cardbot Controller design in my own project?

Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
