v0.2
Changes to rev1:
- bigger 48pin L1 instead of 32pin L0. Advantage: More stable clock with 8MHz HSE
- second PWM channel for buck converter cooling
- second TMP1075 temperature sensor on the backside of the board under the buck to get buck converter temperature
- real 5V PWM according to Noctua specification (required some changes like 3,3V to 5V buck and additional 3,3V LDO)
- USB-C
- 2 new pin header for LEDs
- optimized power and ground planes
