What is Vcc and Vin?
Voltage at the common collector (VCC) is the input of power to a device. Supply voltage is indicated by “V” and “CC” tell you whether the supply voltage is positive or negative. It is labeled with the “+” sign on NPN transistors chips that have semiconductor devices.
What is VCC 5V?
Vcc is the DIP package supply, it should be 5V, whatever the source, but boards might range from 2.7V to 5.5V depending upon design and that datasheet.
What is 5V input?
Input refers to the charging that is being done to the charging device itself. Example: The Input of the charger is – 5V / 2.1A. If a power bank is connected to a wall charger via a Micro USB cable or whatever cable is connected into the Input port then that is Input charging taking place.
What is the VOUT if the VIN 5V?
Voltage Divider
| light level | R2 (sensor) | Vout (if Vin is 5V) |
|---|---|---|
| light | 1k | 0.83 V |
| dark | 10k | 3.33 V |
What is difference between Vcc and VDD?
Technically Vcc/Vee is for bipolar and Vdd/Vss for FETs, but in practise today Vcc and Vdd mean the same, and Vee and Vss mean the same.
Can a 5V power supply use a VIN pin?
I suspect these 2 diodes are forming a Diode-OR for the two possible 5V inputs – the USB port and the Vin pin. This will prevent backpowering whichever of those two power supply sources is not used. That means you cannot use Vin pin as a power output on that version of the board.
What does the 5V pin on an Arduino do?
Outputting power is what the 5v pin is intended to be used for, not as a power input. From the arduino website: 5V. This pin outputs a regulated 5V from the regulator on the board.
What does the VIN pin on an ESP32 mean?
Vin means you can power the board from that pin, when you dont use USB power, so when you power your board via the USB port, you will have 5V on the Vin pin and I have used it to power some motor driver modules without any problem. Yep, it worked hahaha So the ESP32 DOES have 3.3v and 5v output.
Why is The Vbus pin protected by the VIN pin?
This is probably only protecting the USB Vbus pin from being backpowered, if power is being supplied via Vin. If my hypothesis is correct, then that board would allow power out to the Vin pin, when power is supplied via USB.
