First, the pyboard D-series (PYBD-SFxW) is not a single development module. There are three different versions of the module that allow developers to customize the features and capabilities that they need in their projects and can help them meet their budgets. Each module is based on an Arm Cortex-M7 microcontroller from STMicroelectronics and includes the following microcontrollers:
- STM32F722
- STM32F723
- STM32F767
The modules are designated based on the last number in the microcontroller. For example, the module that uses the STM32F722 is the PYBD-SF2W, while the STM32F767 module is the PYBD-SF6W.
These microcontrollers are all capable of running at 216 MHz, which provides a lot of processing power to run MicroPython, ...
