Does just what it should!
For Mini RS232 Level Translator
This is perfect if you have a USB-RS232 converter (like some based on the Prolific chipsets) that insist on 5v or above levels. You can't hook them directly to a Raspberry Pi's pins -- unless you plug in one of these babies. Presto, signal appears and all is well. Tested up to 115k without issues, and I have no reason to suspect it wouldn't be good even higher. Nicely made and something that belongs in your kit if you play with Pi boxes.
I did not plan to rate communication because.... I really didn't need any; order came in, product worked as advertised... happy customer! But I have every reason to believe this seller would do everything possible to keep a customer happy.
