This project integrates test application board, core board, driver board and various accessories.
Canaan Avalon miner A11 series, A12 series, A10 series... can test the signal path status, number of chips, ASIC temperature data, ASIC core voltage data, allowing you to quickly understand the status of the computing power board and facilitate maintenance.
Support chip model: A3201 A3202 A3203 A3204.
The test fixture has 2 power supply modes and 2 test modes:
1: PC power mode
This mode refers to the mode used in normal maintenance of the Hash board. Remove the Hash board and use other PSUs to power the test fixture, which is convenient for simultaneous detection and maintenance.
2: Original power mode
This mode means to test the whole machine without disassembling the Miner, and use the original Miner power supply to supply power to the test fixture.
3: Measurement mode
It means that the test fixture only sends a detection signal (about 0.9V) to the Hash board, but does not perform the board sweep test, that is, the alligator clip will not have a voltage output, which is convenient for detecting the Hash board signal path. Data such as core voltage, number of chips, and core temperature will not be derived from this mode.
4: Test Mode
It means that the test fixture sends a detection signal to the Hash board and starts the test at the same time. At this time, the alligator clip will have a voltage output, and the Hash board will run and heat up. This mode can test the core temperature, core voltage and number of chips.
The following is a brief description and interface function definition diagram:
1: Original power interface (6pin) Do not connect PC power to this interface, otherwise it may cause the device to burn!
This interface is used to power the test fixture with the PSU that comes with Miner, unplug the 6pin cable of the control board of the miner, and connect it to the test fixture. Power the hash board using the conductive strip that came with the miner. This mode does not require disassembly, and the hash board can be tested separately.
2: IO data connector (20pin)
For earlier models
3: IO data connector (14pin)
For models with 14pin IO interface, such as 1066pro 11 series and 12 series.
1: PC power interface (6pin*2) Do not connect the original power supply to this interface, otherwise it may cause the device to burn! This connector is used in PC power mode. Due to the higher voltage, two 6pin cables must be connected at the same time.
2: Foot switch connector
It is used to connect the foot switch, it is convenient to use the foot pedal instead of manually triggering the test button, and the operation is simple.
3: Serial input port
The external serial port connector is used to connect to the mainboard of the test fixture of other brands, such as Antminer, Whatsminer, etc. You can view the test information of the test fixture on the screen.
4: Select switch 1
Chip Type Selector 1
5: Select switch 2
Chip Type Selector 1
By flipping two sets of switches, the ASIC chip model to be tested can be selected. The specific corresponding location is shown in the figure below.
6：USB (GOT) connector
For connecting a computer or mobile phone to view the test results.
(Your computer may need to install USB driver and serial port software, if necessary, you can contact THANOSMINING staff to obtain software and tutorials)
Schematic diagram of the matching position of the ASIC toggle switch:
Please toggle the switch to the ASIC chip model you need to test.
(If you are not sure of the ASIC model, you can find the silkscreen ASIC model on the edge of the hash board)
Schematic diagram of the test fixture panel:
PC mode voltage display
1: Status indicator
The indicator lights have different colors to represent different power states, please refer to the video tutorial.
(see the video tutorial at the end of the article)
2: Measurement mode/test mode, select button
Used to select measurement mode and test mode, press to enter measurement mode, reset to test mode
3: Original power mode test button
When using the original power mode for testing, please use this button as the trigger button.

Testing process:
PC mode: For example, the hash board chip model is A3201
1: Supply power to the test fixture, insert the foot switch, and connect the USB serial port to the computer if necessary
2.: Move the ASIC selection switch to the correct position.
3: The main output power supply is divided into positive and negative clips to the hash board, red is positive, black is negative.
(Please note that the cable connection must be correct and firm, otherwise the test fixture or hash board may be burned out)
4: Connect the cable to the hash board according to the type of the hash board cable interface
5: Step on the foot switch and do not release it: (The test mode and the measurement mode are switched in the PC mode switch)
6: Test mode: start the test, there will be main power output after 4 seconds, and the power will be automatically turned off after the test is completed.
The test results will be fed back to the LED and serial port printing information.
7: Measurement mode: the main output will be generated immediately when you step on it, the test program will not be started, and the power will be turned off immediately when you release it.
In this mode, when the power board is powered on, the C signal always has data transmission, which is convenient for finding problems.
8: Original power supply mode: This mode is generally used for on-machine testing, using the original conductive strip, without dismantling the power board.
Insert the 6PIN head of the original power supply into the test fixture, insert the cable into the hash board, turn on the power, press the original power mode test switch to start the test, and the test result will be fed back to the LED and serial port to print information.
In either case, the negative plate of the main output must not be badly connected or reversely connected, otherwise it may cause irreparable losses.
The PC power input port of the test fixture and the original power input port are of different voltages, and it is forbidden to mix them, otherwise the test fixture will be burned, please be sure to follow it!
