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.
- FTDI FT232R IC: USB to UART interface IC to program micro-controllers via PC.
- RCL components: The exact values of resistors, capacitors, and inductors can be found in the schematic image below.
- Connectors: USB connector, relimate connectors, and FRC cables.
