The principles of S15 and T15 are basically the same, so we use the same detection and maintenance methods
This version contains the basic circuit schematic diagram and chip signal direction and voltage introduction
We are currently publishing in Chinese, the English version will be released soon
The Antminer S15 single hash board has 72 BM1391AE chips, and the signal direction is transmitted sequentially from U1 to U72; the Antminer T15 single hash board has 60 BM1391AE chips, and the signal direction is transmitted sequentially from U1 to U60.
The Antminer S15 hash board has 12 voltage domains, and each voltage domain contains 6 chips.
The Antminer T15 hash board has 12 voltage domains, and each voltage domain contains 5 chips.
It still uses 5 test points for inspection and maintenance
The five test points are: CLK / CO / RI / RST / BO
Some versions of Hashboard have no markup text
For a description of test points, see:
Fix: Description of Antminer Hashboard test points
The test points are divided into two types according to the serial number of the chip:
Of course, some circuit schematics are also provided
