Questions
How big is the ESPLionV1 PCB?
It measures 45 × 35 mm and has 4 copper layers, 1.6 mm thick.
What parts does the ESPLionV1 use?
124 parts, built around the AD8237ARMZ, ESP32-S3-MINI-1-N8, AD5621AKSZ-REEL7 and LM7332MA. 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 ESPLionV1 KiCad files?
From the Angus-McIntyre/ESPLionV1 repository on GitHub, at the commit this page was made from: the board is ESPLionV1.kicad_pcb and its schematic ESPLionV1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESPLionV1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Angus-McIntyre before reusing the design.
