3V you may remove the voltage regulator (desolder) and wire voltage regulator's input and output together (with solder blob jumper or w/ short wire). It really depends on what you mean by sensor.In general, yes: you would just connect the 5v component to the Arduino's 5v output pin, and the 3. Output voltage :5. Transistors are often used, but also the 74HCT125 can be used.3v It's important to note that the application involves a low load since it is for signaling only and will not involve a significant load, -Precision is not a critical factor so I . Actually, the ADuM5401 can provide more current with a 5V input, up to 90mA instead of 50mA at 3.3V) Solenoid lock (requires 12V) GSM chip (requires 4V) To power these components, I need to convert the 42V DC input voltage into 12V, 5V, . I'm currently working on a PCB where I plan to connect the following components: Arduino (requires 5V) ESP32 (requires 3. The sensor will be powered from the 3. Modified 5 years, 9 months ago.3V out, so we'll need to replace it. La qualité du 5V dépend donc du 'fournisseur'.3V out is slightly less, but the isolated ADC section is very low power, about 3mA. For more information see the datasheet.
