I am designing a PCB for a project. On the PCB, I plan on using the STM32F030C8T6 microcontroller. The resulting board does not need to do many tasks. I need the design to be able to do the following:
- Communicate via I2C.
- Allow for programming via SWD.
- Switch some LED's on and off.
Would I need to include an external oscillator in my PCB design? Thank you for your time.
