PIC16F877A DEVELOPMENT BOARD
DESCRIPTION
This PCB is produced to design the circuits with pic 16F877A easier. Sometimes breadboard and jumper make things harder. It has a user button connected to the E0 pin and a user LED connected to the B7 pin. You can easily find and solder all of the equipment. Circuit board is tested and it works very well.
TECHNICAL DETAILS / COMPONENTS
3 pieces 5V pins, 3 GND pins, but unfortunately, I missed the Vin pin. I will include Vin pin to the next version of this PCB. Another mistake that I made is I forgot to add + sign to battery plug’s positive terminal. PLEASE PAY ATTENTION THAT BATTERY PLUG'S GND TERMINAL IS NEAR TO THE C3 CAPACITOR. ANOTHER ONE IS +VIN. The best thing is you can program the PIC16F877A with your pickit without disconnecting the microcontroller. If you have any question please contact me hamzakose69@gmail.com
Lm7805 regulator is used
MAXIMUM INPUT VOLTAGE: 7V - 35V
RECOMMENDED INPUT VOLTAGE: 7V - 20V
