I am currently making a PCB design which I will have it manufactured. I know there are circuit available online, however I just want to make sure if my understanding is correct.
From this schematic, can I omit the RTS# & CTS# pin? Are these pins necessary to successfully transmit and receive data? All I need is to read and write data from and to the microcontroller.
Forgive me with my little knowledge, but can you please give me an overview on how handshake is implemented? is it just simple logic 1 and 0? or it's a bit complicated?
Did you consider using other chips, like the Microchip alternatives, for instance: MCP2221, MCP2221A, MCP2200?
They come in extra-handy packages, including SMD and DIP, and offers UART pins + extra GPIO pins that you can use to, for example, apply external reset signal to mcu.
