Has anyone designed a variant that only takes usb c male/female either as an adapter for a usb c cable or a dongle ?
Not that I know of. Waveshare RP2040-PiZero has a Type C port, but I don’t necessarily recommend it.
I uses a Waveshare RP2040-Zero (not Waveshare RP2040-PiZero) and a USB-A female to assembly a single PICO Remapper. When USB-C female supersede USB-A female, this will be that you want?
