Questions
How big is the Legofruitv2 PCB?
It measures 40 × 80 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Legofruitv2 use?
47 parts, built around the MDBT50Q-1MV2, DRV8837DSGR-MS, AP2112K-3.3TRG1 and CL21B104KBCNNNC. 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 Legofruitv2 KiCad files?
From the lulf/legobots repository on GitHub, at the commit this page was made from: the board is hardware/legofruit/legofruitv2/legofruitv2.kicad_pcb and its schematic hardware/legofruit/legofruit/legofruit.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Legofruitv2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask lulf before reusing the design.
