Were you planning on telling us what it is and what it's supposed to communicate? A link to its datasheet would be helpful.
How about these two things:That's just it. I can't find any info on it. I will try the one who sold it but I can guess that will be a dead end. I can probably program it through the pads but that wouldn't be any fun if the USB connector can be used in some way. I will keep looking.
This is the one I bought: http://www.aliexpress.com/item/Lily...able-device-NANO-for-arduino/32655867610.html
Programming is a little bit special, you need the DigiSpark version of Arduino IDE (google for it!). When uploading, wait for the IDE to ask you to plug it in! If you plug it in too early programming is not possible! The bootloader simulates USB for the first few seconds after powering it, this also causes a delay in starting the program, please allow for this behavior when designing an usage. The bootloader takes some 2k of the memory so 6k remains for programming.(standard attiny85 has 8k of memory) One disadvantage: the power led is quite bright, for some applications this can be a concern (I use this controller for a WS2812 led strip project, the red is showing quite visible when the strip is off)
