Questions
How big is the VoltageTap Bee PCB?
It measures 50 × 110.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the VoltageTap Bee use?
156 parts, built around the TPSM33606S5QRDNRQ1, FCX495, ISOM8110DFSR and TLP176AM(E. 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 VoltageTap Bee KiCad files?
From the Gregification/BeeMS repository on GitHub, at the commit this page was made from: the board is hardware/VoltageTap_Bee/VoltageTap_Bee.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 VoltageTap Bee 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).
