as nobody posted some pictures of the hashboard of the Antminer A3 I'm going to do this for information.
As you can see this is one hashboard, front and back.
PIC16F1704 is on it and also the ADP BEN+ (PWM controlling for MosFET?) and - I think so - an Infinion MosFET - 0901NS

any! datasheet) if I'm not complety wrong. Also some pins for the ICSP programming.
Maybe some of you also want to tell us about the rest of this stuff on it... and/or has some infos and datasheets?
