After some testing, I decided to change my 16F1503 receiver PIC to a 16F1508 which is equipped with an USART module. It's much easier to implement this way....
2 cents....... the LCD and LED's stuff aren't that badly affected by slight power supply fluctuations ... slight. The PIC's and IC's need good stable power 7805 or similar on their own circuit.
Re: Voltage regulation circuit 12V to 5V in 5A range
Are you sure you need 5Amps at 5 volts? That is 25 Watts of power.
Ioannis Today, 20:13And about 35 Watts of power loss on the Linear regulator. This means that you will need a monster heatsink like intel CPU with a...
