B8 Antminer universal hash board tester integrates hash board testing, EEPROM read or write, APW series power supply testing, LM75A full address temperature scanning, fan tester, and many other functions. Compact in size, it integrates a Type-C power interface, allowing it to be powered by a power bank, greatly improving ease of use and portability.
Test model:
Supported Miner models: 19 series, 21 series, 17 series, L3-L5-L7-L9 series, s9-11-15 series, etc. (to be continuously updated)
Supported power supply models: APW17 1215, APW12 1215, APW12 1417, APW11 1721, APW9, APW8.
Supported fan models: DC12V/4-wire fan
EEPROM programming: Read / Write / Erase
Menu Interface Instructions:
1. Powering on directly enters the test options interface.
2. Hashboard test main interface; selecting this will enter the classification interface.
3. The classification interface displays supported models (S19 series, for example, supports Hyd).
4. The classification interface displays supported models (S21 series, for example, supports Hyd).
5. LM75A Full Address Scan: Directly reads temperature information (applicable to models without a PIC chip).
6. APW Series Power Supply Test: Output voltage can be directly set, and the power supply will output the set voltage.
7. EEPROM Editor: Supports read/write/erase.
8. Fan Test (12V DC round power interface).
9. EEPROM Operation Interface (Erase Successful).
10. Hash Board Test, taking T21 as an example: This model lacks a PIC, so it indicates PIC communication failure.
The tester will directly read the LM75A temperature and the number of chips.
11. Hash Board Test, taking S19 as an example: This model has a PIC. The temperature is obtained from the PIC, and the chip count is 0, indicating a faulty hash board. The "RI" signal is not output.
12. Hash Board Test, taking S19hyd as an example: The test temperature and chip count are normal.
Important Note: When the hash board's RI signal is normal, the tester will directly display the number of the damaged chip.
If the entire board has no RI signal, it will indicate that the ASIC is 0.
Simple external interfaces provide an extremely convenient user experience.
Type-C interface allows the tester to be powered by a power bank.
DC12V round power supply interface specifically designed for fan testing.
