Notice:
- When the board is connected to the PC and the PC is restarted, the relays will be toggled several times. This is because of the structure of the FTDI chip.
- The device must be supplied with 12 VDC or order to work.
- There is no protection against reversed voltage! If the VCC(+12V) and GND are reversed the board will be damaged!
- The board can not work without computer

Sascha Quite nice, but could be even better
Seems to be quite well-built; looking forward to see how long it's gonna last in my test setup for doing power cycle tests of embedded devices. Use of standard components (FT245RL) makes it easy to control from Linux. There a two drawbacks that could be addressed in future revisions or products: 1. Like hinted at in the description, the relays glitch during boot-up. This happens even with a USB power supply instead of the PC, so it's not a driver issue. Using an additional latch may help. 2. The board looks like it would fit a DIN rail case nicely, it even has the connectors placed appropriately. Unfortunately it barely does NOT fit: the two connector rows are a few millimeters too wide apart. Having USB and power supply on the sides would have been acceptable (though not perfect), but the 93mm are about the size of the case itself make it impossible to fit. It's good enough for my own test setup, but because of these two issues I can't recommend it to my customers. Their test equipment is mounted on DIN rails and the relays may be wired in ways where glitches may cause short-circuits.

Ye Great Great
The relay arrived in good condition and it's very well-built. I did some basic test on it, and so far no problem with it. I am searching some example code for it, but didn't have much luck. I contacted the support, and they gave me a link, where includes windows software examples. I really like this relay.
