important

Pre-production boards have these issues as the core has changed for better support:

When using DUELink firmware:
- The Uplink JST socket only supports I2C, no UART and no USB. The "legs" are the Uplink USB.
- The board can only be the first board in a Daisylink.
When loading your own firmware:
- Do not use pin PA15. Keep the pin as input.
- Do not use pin PC14. Keep the pin as input.
- Do not use Uplink JST socket. Use USB instead.
- Other boards use QFN32 chip where original John Due Rev A uses QFN28. This touches USB pins so special considerations are necessary.
