Version	Comment
1.0	Initial version Known issues: 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) TYPE-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
1.1	Major changes: Fix microSD card clearance. Pin 16 is now connected to GPIOZ_8. Pin 22 is now connected to GPIOZ_9. Pin 36 is now pulled up. Fan is now connected to GPIOAO_11 (PWMAO_A). Relocated fan header, and switched to a smaller CSI connector. Update CSI, DSI pin definition. Switch wireless module from AP6256 to AW-CM256SM, which requires different firmware. Distro developers are recommended to include firmwares for both modules.
1.2	Major changes: Add I2S data pin on pin 31 and 36
