Review on 🛠️ Hosyond Nano V3.0 ATmega328P/CH340 5V 16M Micro Controller Board Module - Arduino IDE Compatible for enhanced SEO by Adam Hutchinson

All three worked right away, but when I unplugged one of them and plugged it back in, the USB driver no longer recognized it ( The port menu was grayed out ) Colour). This makes it unusable. The problem is not with the driver as the other two are working fine. No problem with the cable because the cable is suitable for others. Tried to rewrite the bootloader. No success. It can be programmed with another Uno as ISP and the "Blink" sketch will work. So it's probably because the CH340 chip is burned out. It's a shame. In this state it is useless.
