Power supply
The board has a DC/DC (BUCK step-down high efficiency) converter that provides a stable +5V
power supply to the PS logic circuits and powers the attached Arduino board and other possible
expansion modules connected to the top. The converter (for external devices) can deliver a
current of 450mA, though we recommend to use only up to 300mA.
