| 1.0
| 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 <code>gpio-fan</code> will be used in device tree.
