I think you have the pin number wrong on the schematic in the wiki page. Pin 1 is GND and Pin 4 is Sig.
Hi,the schematic is right,maybe you have thought that there are some relationship between number pin,in fact,the number of pin is just a identifier of chip,but there have no connection.
Where can i find the eagle files for this?I didn`t find them in forum...
