Questions
How big is the Miniscope v4-Rigid Flex PCB?
It measures 30 × 57.1 mm and has 6 copper layers, 0.8 mm thick.
What parts does the Miniscope v4-Rigid Flex use?
111 parts, built around the ATMEGA328-MU, LMV321IDCKR, MAX14574EWL+ and NOIP1SP0480A-STI. 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 Miniscope v4-Rigid Flex KiCad files?
From the Aharoni-Lab/Miniscope-v4 repository on GitHub, at the commit this page was made from: the board is Miniscope-v4-Rigid-Flex/KiCad/Miniscope-v4-Rigid-Flex.kicad_pcb and its schematic Miniscope-v4-Rigid-Flex/KiCad/IMU.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Miniscope v4-Rigid Flex design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
