Questions
How big is the Esb PCB?
It measures 78 × 90 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Esb use?
102 parts, built around the LPC1549JBD64, VN5E010AH-E, VND5050AJTR-E and T491D226K035AT. 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 Esb KiCad files?
From the usevolt/esb repository on GitHub, at the commit this page was made from: the board is hw/esb.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esb design in my own project?
Its repository states no licence, so its author keeps all rights: ask usevolt before reusing the design.
