Hello everyone,
I am designing a small circuit that uses 5 volts for power. I need to keep the component count low, also there is not much room on the board for components.
I wanted to take 5V from the com port but I am concerned whether this is a good idea, and whether or not it will cause damage to my serial port and/or my board.
The components will consist of a 24LC256 eeprom, an avr micro controller, a MAX232 and two LED's.
Here is a circuit I tested and it works.
Just looking for some advice.
