Initial version
- Lack of clearance around microSD card slot resulting the card will be blocked for insertion. (Workaround: lift the card corner slightly during insertion, so the card can "sit" on that blocking component when fully inserted)
- TYPC-C headers are slightly misaligned.
- PCB mounting hole location is different from Zero, as such a proposed universal case cannot share holes on the USB connector side.
- USB 3 port may not be recognized by the board. (Manually fixed on sample boards)
- GPIO pin 16 and 24 are connected on the same bus. 16 will be replaced by SARADC_CH1.
- GPIO pin 36 is an open drain pin. Works fine for input but need pull up for output.
- Fan's PWM generator is occupied by VDDCPU_B. Preferably an unused PWM pin should go there. Otherwise
gpio-fan will be used in device tree.
- Green LED might be too bright
