4.1 Power Supply (JP: 26, 41)
The onboard voltage regulator provides stabilized 5V supply to the MCU and peripherals.
Even though it is thermally protected against overload, care must be taken when supplying
current for additional circuitry, like sensors or encoders.
JP26 Connects the MCU supply to VCC5; can be used for MCU current measurement
