Questions
How big is the Voltage Sensor Card PCB?
It measures 104.1 × 54.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Voltage Sensor Card use?
62 parts, built around the MEJ1S1205SC and L78L05ABUTR. 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 Voltage Sensor Card KiCad files?
From the odtu/Powerlab repository on GitHub, at the commit this page was made from: the board is Hardware/Voltage-Sensor-Board/Voltage_Sensor_Card.kicad_pcb and its schematic Hardware/Voltage-Sensor-Board/Voltage_Sensor_Card.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Voltage Sensor Card design in my own project?
Its repository states no licence, so its author keeps all rights: ask odtu before reusing the design.
