Review on 🔌 DSD TECH USB to TTL Adapter SH-U09C2 with Built-in FTDI FT232RL IC for Enhanced Debugging and Programming Capabilities by Will Lockhart

I bought this after my previous serial cable (believed to be 3.3v) stopped working after connecting to a 3.3v system. It's very nicely made - it's housed in a transparent case (don't worry about accidental shorts when fumbling) and lets you choose between 1.8v, 3.3v or 5v output voltage (no 2.5v, although DSD has another block that also adds 2.5V). .) A cable is included that connects to the I/O port on the end of the USB adapter that terminates in the 1x1 connector pins - it is approximately 30cm long. While I'm not a fan of flashing lights, at least you know this adapter works. I've had no problem working with a Raspberry Pi as a console cable and have also successfully programmed an Arduino type 2.5V microcontroller. I'm using Linux and no drivers were needed, out of the box, just plug that in game on.
