FTDI (FT232R) AVR Programmer Board to Program Micro-controllers


Introduction:

This design is for a serial AVR programmer PCB that programs micro-controllers using the FTDI's FT232R chip. The FT232R gives a USB to serial UART (Universal Asynchronous Receiver/Transmitter) interface that allows programming of AVR micro-controllers via a PC. This IC has several important features and you can read about them in the link above.
