 The microcontroller is a [STM32F100C8](https://www.st.com/resource/en/datasheet/stm32f100c8.pdf) `U101` from ST in LQFP48 package, which gets its clock from the 24 MHz crystal `X101`. Apart from the fact that all IO pins are used, it is only worth mentioning that RC low pass filters are present at many outputs.
