Which USB Serial Friend? FTDI or CP2104

Post by whatamidoing »

I want to put a ATMega328 onto a breadboard as an Uno-like-clone. I'll get a chip with the bootloader already on it (to start with). I'll just need to program it. Should I get the CP2104 Friend https://www.adafruit.com/products/3309 or the or the FTDI Friend https://www.adafruit.com/product/284

I don't think I'll need to use it to install a bootloader, as I'll use the Uno to breadboard method https://www.arduino.cc/en/Tutorial/ArduinoToBreadboard, but with a Nano 3. The eventual goal is to convert my current uno/nano with a breadboard and a lot of wires to a PCB with a ATMega328 and a serial header for re-programming.

The CP2104 is a heap cheaper. Is there any disadvantage?

The nice thing about the FTDI friend is that it has the DTR line that you can use for resetting the processor and starting the bootloader.
