PicoBT Universal Miner Tester User Manual

PicoBT is a professional miner tester that electronics repairmen and engineers can use to diagnose and repair more than 120 models of ASIC miner hash boards and 20 models of smart power supplies manufactured by Whatsminer, Antminer, Aixin, Cheetah, and Dragon companies.

Compared to traditional miner repair methods, the PicoBT tester, with its unique features, can reduce diagnostic time by at least 10 times and increase diagnostic accuracy by 4 times when troubleshooting minor components, namely, hash boards and smart power supply units.

II. PicoBT tester operation guide

This is the main interface of the latest version of PICOBT:

After entering the page, you will see three types of hash boards: Antminer, Whatsminer, and Innosilicon. Use the green and yellow buttons on the tester to select the type and model of hash board you need to test.

(1) How to test the Antminer hash board using the PicoBT tester? We'll use the S19k Pro hash board as an example:

To test the Antminer hash board, the connection should be made as shown in the image below:

This is a schematic diagram of the test results:

1: Represents how many times the hash board is tested

77: Represents the number of healthy ASIC chips

0: Represents the number of healthy chips detected from the last ASIC to any chip connected via the oscilloscope probe's test points (RI/RO/RX signals).

Note: The positive terminal of the oscilloscope probe must be connected to the RI/RO/RX signal of any chip, and the negative terminal of the oscilloscope must be connected to the negative terminal of that chip.

T1: Represents the test result of the air inlet temperature sensor chip

T2: Represents the test result of the air outlet temperature sensor chip

ONE: This is the hash board test mode switch. ONE means testing only once; pressing this button will show 999, which means automatic repeated testing.

PIC: It is recommended not to select this option, as it has already been set at the factory.

BACK: Represents returning

TEST: Represents starting the test

(2) How to test the Whatsminer hash board using the PicoBT tester? We'll use the M32 hash board as an example:

To test the Whatsminer hash board, the connection should be made as shown in the image below:

This is a schematic diagram of the test results:

1: Represents the number of hash board tests

74: Represents the number of healthy ASIC chips

0: Represents the number of healthy chips detected from the last ASIC to any chip connected via the oscilloscope probe's TXD signal test point.

Note: The positive terminal of the oscilloscope probe must be connected to the TXD signal of any chip, and the negative terminal of the oscilloscope must be connected to the negative terminal of that chip.

TEMP: Represents the temperature sensor chip test result

193020A: Represents the ASIC chip model

ONE: This is the hash board test mode switch. ONE means testing only once; pressing this button will show 999, which means automatic repeated testing.

RST: Represents the RST signal voltage switching button. It can switch between 0V and 1.8V to test the health of the RST signal.

BACK: Represents return

TEST: Represents start testing

 III. PSU tester operation guide

PicoBT tests the power supply output voltage without requiring any computer equipment. 

Cable connection during APW12 testing:

Cable connection during P221 testing:

1. Connect all cables

1) Connect the 6P power cable to the PicoBT;

2) Connect the 4P regulated line to the PicoBT;

3) The 6P power cable and 4P stabilized voltage cable are connected to the APW12.

4) Connect the 220V power cord to the APW12 to supply power to it.

2. PicoBT enters power mode

1)First,press and hold the white button, then press the switch on the left side of the PicoBT.

We will see a new page like this:

3. Select the power model

1) Press the orange button to view all power models that the PicoBT can test.

2) Select APW12 using the green button, then press the white button to start the test.

4. Perform the test

1) Switch the multimeter to the DC voltage range and press the white button on the PicoBT to start the test.

2) Connect the positive and negative leads of the multimeter to the positive and negative terminals of the power supply, respectively. The multimeter reading  should be approximately 15V.

Note: We can enable all Innosilicon PSUs by selecting the "T2T15.0v" option.

IV. EEPROM editor operation guide

Copy, flash, and save EEPROM content for Whatsminers and Antminers; we can permanently save 4 EEPROM data in the PicoBT tester.

This is a diagram showing the cable connections:

To enter the EEPROM editor, connect the input voltage cable to the tester (the On/Off switch must be closed). Press and hold the white key for 2 seconds to turn on the switch. We will see a new page on our display, as shown below:

Now press the white key to enter the EEPROM editor. Below we will see the following EEPROM editor page:

Note 1: If a connected hash board is selected, (past) data can be copied or programmed to the hash board connected to the tester.

Note 2: Any data copied from the hash board or the data of the 4 permanent memories will be temporarily saved in the temporary memory.

Note 3: There are 4 permanent memories on the tester; we can save 4 EEPROM data in these memories.

Note 4: Any data we copy from any option will appear here.

Note 5: We should choose WTS or BIT option by pressing this blue key. If the hash board is "Whatsminer," choose WTS; if the hash board is "Antminer," choose BIT.

We can select a memory by pressing the green key on the tester, the red key to copy the content of any selected memory, and the white key to paste the content of any selected memory.

V. Activation tutorial of PicoBT test fixture

Please follow the steps below to correctly activate the PicoBT test fixture:

1.Insert one end of the DuPont cable into "② SWCLK", "④ SWDIO", "⑤ or ⑥ GND", "⑨ or ⑩ 5.0V" of the programmer.

2. Insert the ST-LINK V2 programmer into the computer, and then connect the other end of the Dupont cable to the SWDIO, SWCLK, GND and 5V pins of the test fixture.

3. Download the STM32 ST-LINK Utility software and install it on the computer.

4.Click the iconon the STM32 ST-LINK Utility software to start connecting the test fixture.

5.Click the iconto start loading the new firmware (with Hex format)

6.Click the iconto start programming. When "OK" appears on the interface of the STM32 ST-LINK Utility software, it means that the test fixture has been successfully activated. At this time, the tester will also restart.
