Analogue In means it has an ADC capability on the channel. This can sample at a very high frequency. It is 15 of these

PWM means we have a Hardware PWM signal with a very high frequency capability. It is 23 of these.

Analogue out means it connect to a DAC. It is 2 of these,

Digital In & Digital Out is on all 32 channels.

Servo is available on all 32 channels and is the default configuration.

Software PWM means we bit-bang the pin in software to create a PWM signal. Max frequency is ca 10KHz. Available on all 32 channels.

An updated version of this table can be found in Annotated Schematics (coming soon). Pin’s have all cababilities as per STM32F105RB capabilities, but more advanced features will need custom modified firmware to access.
