Hi, I have got some chinese arduino nanos. I measured 3.3 voltage and I have 3.7v instead. At the moment, it is driving a nrf24l01 chip and voltage is a bit high. How can I solve it , advices . Thanks , S.Ancelot

3.7v instead of 3.3v output on arduino nano

For powering external devices use an external voltage regulator.
