Hardware layout and configuration
Connector
CN3
CN4
1. Only one USART is available and it is shared between Arduino Nano and VCP. The selection is done by
remapping (no hardware configuration to change).
2. D3 and D5 PWM are using same channel of TIM2_CH3.
3. Limitations on A4 and A5, D4 and D5, related to I
bridges
4. D7/D8 shared with OSC_IN/OSC_OUT.
5. No PWM on D9, D10, D11.
6. SPI_CS is made by GPIO.
7. PA2 exclusive with VCP_TX.
