Prototyping Board for PIC16F876 Programmer, Experiment
Prototyping Board for PIC 16F876 testing for PIC16F876 With this circuit board, you can program your microcontrollers from 16F87X family and the 18FXXX comprising 28 pins. this arrangement allows you to test its operation without having to remove the component (PIC) of the motherboard created. You should then make cards from the connectors available. On each of the connectors, we find the various inputs / outputs of microcontrollers. We must keep in mind that I create for this circuit test a PIC 16F876. This means that if you want to use another PIC platinum with this test, it will check its pin before use itself.
