Questions
How big is the Ecksdee wifi card PCB?
It measures 120 × 72.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Ecksdee wifi card use?
37 parts, built around the ESP-07S, CH340K, AMS1117-3.3 and SN74HC688PWRE4. 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 Ecksdee wifi card KiCad files?
From the indrora/xd-wifi repository on GitHub, at the commit this page was made from: the board is ecksdee-wifi-card.kicad_pcb and its schematic ecksdee-wifi-card.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ecksdee wifi card design in my own project?
Its repository states no licence, so its author keeps all rights: ask indrora before reusing the design.
