Bought this one to use it as a status display on my RC2014 based bulletin board system ("RC-BOX"). Not very complicated to assemble but placing and soldering all those resistors properly took some time. IC sockets, capacitors and 7-segment modules were done very quickly after that. Using the module is very straight forward and will work with assembler, BASIC, C, PASCAL etc. out of the box.
The documentation includes all the information you need to successfully build and operate the module. Want a neat RC2014 clock or status display that is easy to use? Then this module is perfect for you!
P.S: shipping from UK to EU mainland took very, very long as my order was shipped a few weeks before new customs regulations came into effect. I suppose that for UK residents things will be much, much faster. Communication with the seller was exemplary all the time.
Needed to clean the PCB in order to get solder to adhere to some of the pads, but otherwise it was easy and straightforward to assemble and the instructions were good. The demo program worked first time and now I'm hooked writing software to translate text to allophones
