Review on JBtek USB to TTL Serial Cable - Windows 8 Compatible Debugging Cable for Raspberry Pi USB Programming by Noah Jess

Pro: - Inexpensive. Broad OS support for less than $10. PL2303 is supported by most major operating systems. Can be set to v5 or v3.3 output power. The PL2303 has a built-in DC/DC converter. The converter works reliably. Cons: - Average fit and finish. The converter housing is easy to dismantle and the circuit board assembly is sufficient. Mechanically unreliable. The shield around the USB connector is not soldered, so repeated use may damage the part. Attention:! Open the converter case and solder the USB connector case to the pads around the circuit board once you receive it. ! The connector bends around the USB signal pins, which can lead to either a poor connection or failure over time. USB can be easily removed; It's a tight-fitting case that's held together with plastic pins, so don't be too rough on it. The circuit board inside has an unfilled through hole for v3.3. However, you need to cut the red 5.5V wire and solder it for the 3.3V output. .
