gasman, thanks
gringo128, I am not planing to manufacture new batch yet but I still have a few assembled boards ready to go. If you are going to buy some of them you are welcome. Just send me a mail or a private message by this forum. Maybe I will start the new batch after I send all boards from this batch and get enough requests for new batch (something like >=10). But I am not sure about this because now I am a lot involved with another job.
