Because I don't like waiting for the bootloader to power up the MCU to hold the power on.
It's hard to find such a circuit, so I've created this one for educational purposes.
It's similar to the "Mini Pushbutton Power Switch" prod...

To be referred to as electronic, rather than electrical, generally at least one active component must be present. The combination of components and wires allows various simple and co...
