A universal RS232 adapter

I work a lot with small and larger development boards and was looking for something affordable to connect me with this series.
This product has three very good properties.
1. With the switching between 3.3V and 5V, it advertises itself well for just about everything, which one wants to join it.
2. The rock solid FT232RL chip by FTDI will probably not be accepted by almost any operating system.
3. It has also two LEDs for RX and TX, where you can see whether the data is transferred or not.

Paying for products that use only one voltage in some cases more than four times.

Although there are no cables attached, but which is likely to be difficult to expect at the price, which should, however, in the range are each interested.

The power strip is correctly labeled, the processing "very" well.
I would recommend this product without restrictions.
