Hi! I recovered some Arduino Nano boards, but it seems that the MCUs are burned, so I thought of using the CH340G driver, I had an ATMega8 that I didn't know how to program it, so I think this circuit would be useful to program microcontrollers. I searched the internet for a circuit with this CH340G, I found many variants, and I started from this circuit:
From what I understand, this circuit is useful for microcontrollers that contain a bootloader. This circuit would be an alternative to FTDI: [Ft232rl ftdi 3.3v 5.5v usb to ttl serial adapter module converter geekcreit for arduino - products that work with official arduino boards Sale - Banggood.com]
I've never used anything like this before, so I'm not sure how it will work, so I opened this post. Do you notice anything wrong in the circuit?
