1, Support input DC 6.5 to 32V(from blue terminal block), Output DC 5V to Raspberry Pi, Output maximum current 3 Amp, Conversion efficiency 90%.
2, If your power supply system is DC 12V or 24V, then you can use this HAT module to conveniently conversion to DC5V to provide power supply for your Raspberry Pi, and these screw terminal blocks are very convenient for GPIO breakout connects. The module can support Raspberry Pi A+ 3A+ B+ 2B 3B 3B+ 4B (of course, Zero and Zero-W can also be supported, but only two screw holes can be fixed).
3, If you don't want to use the step-down coverter function, you can still use Raspberry Pi USB power supply port to supply 5V power, the step-down converter circuit will not affect your USB power supply. BUT, you can only choose one of the two, and you cannot connect the two power supply modes at the same time, otherwise your Raspberry Pi module may will be damaged.
4, Terminal block with GPIO labels, pitch 3.5mm/0.138", wire size range 26AWG to 16AWG, strip length 5mm, screw M2 steel, pin header and cage copper. Support 40-pin GPIO expansion connection, pin height 8mm/0.32"
5, Package included: 1x RPi step-down DC-DC Converter HAT, 4x M2.5x16mm nylon standoffs, 4x M2.5x6mm nylon standoffs, 4x M2.5 nylon nuts (NOTE: the item not include Raspberry Pi module).
