I would say it's not an 'rPi clone' just a board which happens to be based upon the RP2040.• Why has the manufacturer produced a rPi clone that has a different pinout from the original board? (Not a 'dig', just genuinely curious)
As for the differences, which are considerable, I would presume it's because they thought their footprint, contiguous GPIO, contiguous ADC, access to all 4 ADC, making all 30 GPIO available, would be more suited to their audience than the Raspberry Pi footprint.
It's quite a nice footprint IMO apart from the 0V/GND between 4 and 5 plus 12 and 13. I would have put 0V at 1 and 20 so all the GPIO on that side were contiguous, or moved them so 0-7 were 8 contiguous GPIO, 8-17 were 10, which would be useful for 0V, 8-bit VGA, plus two sync.
Should be easy enough to figure out given every pad is silk-screened. The only real unknown is what the VBUS and VIN circuitry would be and that can likely be figured out with track continuity testing.• Does anyone here have a schematic/pin out for this purple clone?
But this seems to be the pinout, viewed from component side, USB-C at the top -
