I've ordered one, and i'm going to try and figure it out.http://www.dealextreme.com/p/jy-mcu-16x-digital-tube-yellow-led-module-104311Here is all the reference info I could find: Schematic: http://ljy99731.13.dns222.net/download/LM1640_sch.pdf Datasheet: http://ljy99731.13.dns222.net/download/tm1640.pdfIs it similar to the TM1638, for which an arduino library has already been built?http://code.google.com/p/tm1638-library/I've contacted the author of the arduino TM1638 library, and he's also got one of these units on order, to try and figure out.
