I use an arduino nano clone and I see it has a voltage regulator “Ams1117 5.0 h517” in it. As I understand this regulator provides a steady 5V. But my arduino also has a 3.3 V output pin and I cant find the voltage regulator of 3.3 V in it.
The thing is this: I am using 3.3 V of arduino to power nrf24l01+ and as far as I know this 3.3 V provided by arduino is a shitty voltage, it is not steady. So I would like to find the 3.3 v voltage regulator on the arduino board and replace it with a better one. But I cant find it on the board.
