Hello,
I have a barebone PIC16F877A development board in our college laboratory, which were missing power 100nF ceramic caps + the main 10uF power cap.
Now still one problem which is to provide a constant 5V input because the power supply is a lab bench power supplies, and students may by mistake crank the power a bit which of course would fry the PIC chip or the PICkit 3 which is a bigger problem than the PIC chip because we don't have many left in the warehouse.
This is a picture with the board and putting aside the lm7805 and the required caps.
My question now is: are these 2 caps enough for the lm7805 ? or I have to add other stuff ?
