Review on 🔌 Get Reliable Connectivity with DSD TECH USB to TTL Serial Adapter FT232RL Chip Compatible with Windows and Mac OS X by Quintin Gore

Used it to install an Arduino bootloader on some STM32F103. worked fine Update: I had a problem with STM32, I wanted to reflash the bootloader and couldn't start it. Tried a second STM32, couldn't flash it. I then looped through the FT232 connecting TXD to RXD and connecting via putty to verify it was the card. Of course, RXD stopped working. So it worked once, kept in an anti-static bag for about a week, and then when I needed it again it didn't work.
