Questions
How big is the BDEcho AKit Sidekick r3 PCB?
It measures 29.8 × 68.1 mm and has 4 copper layers, 1.6 mm thick.
What parts does the BDEcho AKit Sidekick r3 use?
49 parts, built around the LTV-355T, WS2812B, SJ2-3594A-SMT-TR and SP-3541. 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 BDEcho AKit Sidekick r3 KiCad files?
From the Boondock-Echo/Boondock-Hardware repository on GitHub, at the commit this page was made from: the board is Boondock-Echo/PCB/BDEcho-AKit-Sidekick-r3-KICAD/BDEcho-AKit-Sidekick-r3.kicad_pcb and its schematic Boondock-Echo/PCB/BDEcho-AKit-Sidekick-r3-KICAD/BDEcho-AKit-Sidekick-r3.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the BDEcho AKit Sidekick r3 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Boondock-Echo before reusing the design.
