1. When STM32F405RG (in LQFP64) is mounted, C20 and C23 must be populated!
2. When STM32F103RB (in LQFP64) is mounted, C20 and C23 must be connected in short circuit (for example via 0 Ohm resistor)!
3. U1's symbol refers to STM32F103RB (in LQFP64).
For the STM32F405RG (in LQFP64), please see the corresponding datasheet!
