RT4K donut dongle
svirant/DonutDongle
Arduino Nano based hub that connects your digital and analog console switching setup with the RetroTink 4K and/or RetroTink 5x/OSSC for Auto Profile switching
Boards in 9 GitHub repositories, designed in KiCad, that use the SN74LVC2G07DBVR by TECH PUBLIC (-40℃~+125℃ 1 1.65V~5.5V 10uA 2 2.2ns@3.3V,50pF 24mA 24mA 74LVC Schmitt trigger SOT-23-6 Buffers, Drivers, Receivers, Transceivers ROHS). See how each wires it, with its parts, size, README and files; the SN74LVC2G07DBVR’s symbol, footprint and pinout are on its own page.

NathanHowell/orin-nano-controller
Four Jetson boot/control straps land on the 12-pin right-angle socket (J2). They are driven by two SN74LVC2G07 dual open-drain buffers: IC1 handles the APO and RESET lanes, IC2 handles RECOVERY and POWER.
