Overview
Xilibot is an open-source printed circuit board by gcobos, from the gcobos/xilibot repository on GitHub. It is a 2-layer board of 53.3 × 35.6 mm with 11 parts on 24 nets, routed with 167 tracks and 10 vias.
It is built around the WEMOS D1 MINI. Its parts include 3 ICs, 3 connectors, 2 resistors, 1 capacitor and 1 switch. It belongs with the robots and motor control boards and the ESP8266 boards of this library.
Main components
1README
README.mdXiliBot
A self-balancing robot with a LCD screen to show faces, and a color sensor at its bottom.
In the hardware side, this repository contains the FreeCAD model, STL pieces to print, and PCB circuit desing in KiCAD.
In the software area, it includes the robot source code, which is a modified version of the B-Robot EVO2, a remote controller made in Unity3D that uses UnityOSC library to send commands to the robot, and a Web controller that uses Blockly to control the robot using visual programming. Blockly requires to start python/webserver.py to be able to send UDP packages to the robot.
This robot uses a Wemos D1 mini as the "brains", and it is configured to create its own access point, so that the controller connects to the robot's wifi.

Questions
How big is the Xilibot PCB?
It measures 53.3 × 35.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Xilibot use?
11 parts, built around the WEMOS D1 MINI. 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 Xilibot KiCad files?
From the gcobos/xilibot repository on GitHub, at the commit this page was made from: the board is circuits/xilibot.kicad_pcb and its schematic circuits/xilibot.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Xilibot design in my own project?
Its repository states no licence, so its author keeps all rights: ask gcobos before reusing the design.
