*Q:How do I judge that the voltage of the Core+ is 3.3V or 5V?
 +
**A:Look at the resistor. If the R1 is welded, it is 3.3V. And if the R2 is welded, it is 5V.
 +
*Q:Can I use 3.3V voltage to supply power to the Core+ of 16m clock frequency?
 +
**A:It is not recommended . If the voltage is too low, it is easy to be unstable.
 +
*Q:Can I use 5V voltage to supply power to the Core+ of 8M clock frequency？
