Questions
How big is the Esp03-usb jtag PCB?
It measures 97.8 × 49.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Esp03-usb jtag use?
58 parts, built around the 93LC46/P, FT2232HL, LM1117-3.3 and MMBT2222A. 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 Esp03-usb jtag KiCad files?
From the jcmvbkbc/esp03-breakout repository on GitHub, at the commit this page was made from: the board is hw/esp03-usb-jtag.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp03-usb jtag design in my own project?
Its repository states no licence, so its author keeps all rights: ask jcmvbkbc before reusing the design.
