Use PS as Nano expansion board
[Fig. 26.1 – POWER SHIELD + Arduino NANO + some other shield]
Because PS is compatible with almost all Arduino-type boards, it can also be used as an
expansion adapter from Arduino NANO (or MICRO*) to the Arduino UNO platform for
connecting it to other extension modules. Use the low-profile male pin headers to connect
Arduino NANO.

Since the PS is supported here, you can arrange for better cooling at higher loads; put a
fan to blow along the board or place the device in a well-ventilated location.
General tips and warnings
● Only operate with a safe constant voltage up to +32V (absolute maximum).
● For protection against short circuits, always connect the power supply via a 10…30A
fuse (~25% higher than the maximum load).
● For the V+ and GND power supply input for one board you can use 2.5mm
2
cross-section monolithic (or soldered) wires or 1.5mm
2
with ferrules.
● For outputs, use 1 monolithic wire or soldered wires or 0.75mm
2
with ferrules.
● Do not put (balancing) resistors directly in the inputs. Resistors must be separated by
wires at least 10cm long.
● Connect the power supply only when you are sure that everything is connected correctly.
