Hi folks!
Just as usual, whenever i receive a new miner - i always look at the inside of it. Its just my curiosity when it comes to electronics, need to deal with that in a proper way... And the only way is pop that thing straight open!!

Its very clear that with the latest miners, Bitmain have stepped up their game a bit. These chips and boards looks really professional when looking at them visually, thinking of how it all looked back in the earlier days of Antminer.. Damn, thats a big change! From using 100+ chips, down to a total of 12 chips is a big change. Wonder, is it actually only Equihash these chips can do?
There are no external memory, so memory needed for Equihash is onboard chip.
This time ive added watermarks on the images.
Lets start with the overall look of the miner:

It looks really nice, right?
Its small, but slightly noisy with the stock fan thats mounted on it.
Ive had this thing running at 750 Mhz for over 24hrs now, producing about ~16 kSol/s continously. Temps are about ~62c with fans at a static speed of 85%. On that time there have been no rejects reported either by miner, or by pool! And 0 HW errors.
Time to see whats inside!!

Overall backside of PCB:

So, the PCB have a clean layout. Voltage regulation unit is very similiar, if not identical to B3. PIC16F1704 is used for communications, so it may be possible to adjust chip voltages very similiar to the L3 voltage script on this forum.
The chip used for the Z9 Mini is called BM1740, and this time they have used proper cooling paste (B3 only had cooling pads). There is no information or datasheets available for BM1740 chip as far as i know. There is no external memory, so the chip contains atleast enough memory for Equihash onboard.

So there is that. Next up in line is E3, they should start shipping sometime next month if i remember correctly. Like my post? +1 Merit!
