Design-stage RP2040 USB-C microSD reader: KiCad hardware, verification evidence, UART bring-up firmware, and assembly plan. Unbuilt and untested.
Boards in 5 GitHub repositories, designed in KiCad, that use the 74LVC125APW by Nexperia (-40℃~+125℃ 1 1.2V~3.6V 2.5ns@3.3V,50pF 24mA 24mA 4 40uA 74LVC Schmitt trigger Tri-State Unidirectional TSSOP-14 Buffers, Drivers, Receivers, Transceivers ROHS). See how each wires it, with its parts, size, README and files; the 74LVC125APW’s symbol, footprint and pinout are on its own page.
