Questions
How big is the LegoRCHub 10ch PCB?
It measures 39.3 × 55.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LegoRCHub 10ch use?
50 parts, built around the ATTINY3226-XF and DRV8872DDA. 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 LegoRCHub 10ch KiCad files?
From the EmuTM/LegoRCHub repository on GitHub, at the commit this page was made from: the board is PCB/LegoRCHub_10ch/LegoRCHub_10ch.kicad_pcb and its schematic PCB/LegoRCHub_10ch/LegoRCHub_10ch.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LegoRCHub 10ch design in my own project?
Its repository states no licence, so its author keeps all rights: ask EmuTM before reusing the design.
