I'll discuss the pros and cons of the CH341a, EZP2023+, and the TL866-G3. I had to buy all 3 to figure out which worked best for my needs. Now you won't have to. :). If you find this useful, please like and subscribe for more valuable content.
I have compiled a playlist of videos you'll find interesting if your going to do BIOS flashing. It will pop up at the end of the video.
