Make a Roomba Smart via MQTT
RoombaESP is an open-source printed circuit board by foorschtbar, from the foorschtbar/RoombaESP repository on GitHub. It is a 2-layer board of 69.9 × 27.9 mm with 11 parts on 19 nets, routed with 105 tracks and 20 vias.
It is built around the WEMOS D1 MINI. Its parts include 5 resistors, 4 connectors and 2 ICs. It belongs with the ESP8266 boards of this library.
This project is a Add-On PCB for the Roomba vacuum cleaner robots of series 500/600/700. It uses the open interface of the Roomba to control the robot via a ESP8266 microcontroller. The PCB is designed to be mounted on top in a 3D printed case and add

It measures 69.9 × 27.9 mm and has 2 copper layers, 1.6 mm thick.
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.
From the foorschtbar/RoombaESP repository on GitHub, at the commit this page was made from: the board is _pcb/RoombaESP.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask foorschtbar before reusing the design.
