This is the a good board for learning ARM. Cheap. Very powerful. Arduino compatible.

The board has 2 parts:
1. Debugger (ST-LINK)
2. Actual MCU

The form factor is the same for all Arduino-compatible Nucleo boards. The actual board you have depends on the MCU itself. And the MCU choice is largely determined by the Cortex version you need. In our case, we want to used the Cortex-M4 because it has DSP and SIMD. The STM32F446 MCU is the cheapest M4 at the time of writing.
