Questions
How big is the Sanket 4.0 PCB?
It measures 92 × 92 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Sanket 4.0 use?
52 parts, built around the SN74LVC1G17QDCKRQ1, MAX4372TEUK+T, TPS62812QWRWYRQ1 and TPS25200DRVR. 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 Sanket 4.0 KiCad files?
From the Student-Satellite-IITB/Communication-Subsystem repository on GitHub, at the commit this page was made from: the board is DevelopmentBoards/ADS_v4/Sanket Deployment board/sanket 4.0.kicad_pcb and its schematic COMM Board/V2.0/TransceiverBoard/RF.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sanket 4.0 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Student-Satellite-IITB before reusing the design.
