Actually, let’s map that clearly:

Remove the 5V jumper and feed 5V from a reliable source (or Arduino’s 5V pin if current <200mA). This prevents back-EMF from resetting your Arduino.

The servo header shares the Arduino’s 5V regulator. A stalled servo (e.g., MG995) can draw 1A+ and instantly reset your Uno. Remove the +5V jumper and power servos from a separate 5V/3A UBEC.

The shield stacks directly on an , Mega 2560 (partial pin usage), or Nano (with careful alignment). Below is the critical mapping:
