Questions
How big is the Gadas MSE Slave Module PCB?
It measures 229.2 × 100.8 mm and has 6 copper layers, 1.6 mm thick.
What parts does the Gadas MSE Slave Module use?
576 parts, built around the OPA2189ID, TLV2888D, OPA2210ID and LMT86LP. 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 Gadas MSE Slave Module KiCad files?
From the Gady159/Gadas_MSE_ELoad repository on GitHub, at the commit this page was made from: the board is Kicad/Gadas_MSE_Slave_Module/Gadas_MSE_Slave_Module.kicad_pcb and its schematic Kicad/Gadas_MSE_Master_Backplane/Gadas_MSE_Master_Backplane.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Gadas MSE Slave Module design in my own project?
Its repository states no licence, so its author keeps all rights: ask Gady159 before reusing the design.
