Question 4

The power terminal labeled 3V can be used as an output or input? (with a voltage of 3V)

Accepted Answer

As an output: If the micro:bit is powered by USB or battery, then you can use the 3V pin,you can use the 3V pin as a power output to power peripherals. to power peripherals.

Answer

As ground: to complete a circuit

Answer

As input: If the micro:bit is powered by USB or battery,

Answer

As an output: If the micro:bit is NOT powered by USB or battery, then you can use the 3V pin, to power peripherals.

Question 5

Which two terminals, must never be connect together?

Accepted Answer

The pins labeled 3V and GND are related to the board's power supply and should NEVER be connected together.

Answer

The Large PINs should not never be connected with Power Terminals.

Answer

You must not connect together terminals 0 and 3V

Answer

The pins labeled 0 and 1 are the Large Pins, often called "general purpose input and output"and should never connect together.
