Questions
How big is the Cell Balancing testing PCB?
It measures 27.9 × 48.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Cell Balancing testing use?
29 parts, built around the DMN62D0U and TS4148. 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 Cell Balancing testing KiCad files?
From the Gregification/BeeMS repository on GitHub, at the commit this page was made from: the board is hardware/Cell Balancing testing/Cell Balancing testing.kicad_pcb and its schematic hardware/CAN DC SS switch/CAN DC SS switch.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cell Balancing testing design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
