Antminer S15 and T15 Hashboard repair guide
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
Antminer S15 and T15 single hash board uses a total of 72 hash chips, the model is "BM1391AE", and the signal direction is sequentially transmitted from U1 to U72.
Antminer S15 and T15 hash boards have a total of 12 voltage domains, and each voltage domain contains 6 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:
The test points are divided into two types according to the serial number of the chip:
Of course, some circuit schematics are also provided
