Lig is an open-source printed circuit board by C3MA, from the C3MA/lightpanel repository on GitHub. It is a 2-layer board of 100 × 100 mm with 68 parts on 106 nets, routed with 808 tracks and 82 vias.
It is built around the WEMOS D1 MINI, ARDUINO UNO R3 and WS2812B. Its parts include 34 diodes, 18 connectors, 5 capacitors, 2 resistors and 2 ICs. It belongs with the ESP32, ESP8266 and AVR (ATmega, ATtiny) boards of this library.
###Import application note Do not chain Multiple boards while powering only via USB!
The Voltage converters will reverse feed the second board, and in the process kill most of the LED's on the first board!
ESP32C3 notice: If flashing while connected to the board, the ESP might damage it's

It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
68 parts, built around the WEMOS D1 MINI, ARDUINO UNO R3 and WS2812B. 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 C3MA/lightpanel repository on GitHub, at the commit this page was made from: the board is lig/lig.kicad_pcb and its schematic lig/lig.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask C3MA before reusing the design.
gk977246/Openmower_Brushed
I have rebuilt a Bosch Indego800. It had no RPMSensor on the mowing motor, so i added magnet and hallsensor myself. It is easily possible, to convert any old mower with brushed motors, to openmower with RTK.
