Questions
How big is the FlexLogic EVB PCB?
It measures 100 × 100 mm and has 6 copper layers, 1.62 mm thick.
What parts does the FlexLogic EVB use?
311 parts, built around the LCMXO2-1200HC-4SG32I, ESP-12F, ADS1115IDGSR and CC6920SO-10A. 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 FlexLogic EVB KiCad files?
From the y-suyama/FlexLogic_EVB repository on GitHub, at the commit this page was made from: the board is FlexLogic_EVB.kicad_pcb and its schematic FlexLogic_EVB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the FlexLogic EVB design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
