PowerShield - an accessory to connect to STM Nucleo boards

The STM Nucleo boards have a "kind of" R3 compatible pinout. The most powerful boards run CircuitPython and may be used for some interesting projects, yet they are not completely o.k. with AutomationShield devices. The most obvious omission is the lack of 12V source. This could be solved by a fairly simple accessory shield, let's call it PowerShield, that would:

  • Let the user select between as-is input and a 12 V regulator (or make the selection automatically)
  • Provide overcurrent protection
  • Provide screw-in terminals for better power possibilities, possibly let the user select which is used.
  • Post-stabilize voltage source
  • May borrow some ideas from RuggedUino: https://www.rugged-circuits.com/ruggeduino-1-1 for power stabilization.
  • ... etc.
