Serial Monitor

Hello

For my project i will convert the Arduino to pcb. I read how it done and understand the process.
i will program the ATmega chip from the Arduino board then remove it and put it in the pcb. But i need to read from the “serial monitor”, so what i need to add to the pcb to do this.

thank you

I use a USB-TTL cable to connect my PCB (Veroboard) Atmega 328s to my PC. It connects direct to Rx Tx GND and, via a capacitor the RTX line connects to Reset.

The most popular options are the WCH CH340 and FTDI FT232. Other common options are Silicon Labs CP2102 and Prolific PL2303.
