Canaan Technology Launches New Avalon A13 Series Bitcoin Miners

Canaan Technology Launches New Avalon A13 Series Bitcoin Miners According to the latest news, Canaan Technology announced the launch of the new Bitcoin miner Avalon Made A13 series, including Avalon A1346 and Avalon A1366. Canaan Technology said that the new generation of miners uses advanced ASIC technology, and the A13 series will include two different models. Compared with the 90 to 100TH/s hash rate offered by the A12 series, the A13 series has both hash rate, and energy efficiency has been enhanced. Canaan's CEO said the all-new A13 is a milestone in the company's over-computational energy consumption analysis. The model A1346 has a hash rate of 110 TH/s and an energy efficiency of 30J/TH. Model A1366 has a hash rate of 130TH/s and an energy efficiency of 25J/TH. Comparing the energy efficiency ratio of Bitmain's flagship S19 XP of 21.5 J/TH with that of Bitmain's M50S of 0.026j/Gh, the new series of A1346 is "very competitive" in terms of efficiency at

How to use Avalon hash board tester?

How to use Avalon hash board tester?

Avalon hash board tester tests data such as signal path status, number of chips, ASIC temperature data, ASIC core voltage, etc. It is a professional high-quality chip test fixture that integrates application board testing, core board testing, driver board testing, and various accessories testing. Help miners quickly understand the status of the Avalon miner hash board and accurately locate the fault of the hash board chip.
Avalon hash board tester
Avalon hash board tester is suitable for Avalon miner A10 series, A11 series, A12 series, etc.

Avalon hash board tester interface description:

interface description

1. Original power interface (6Pin)
Please do not connect the PC power supply to this interface. Otherwise, it will easily cause the device to burn!
This interface is used to supply power to the hash board tester for the PSU that comes with the miner. Unplug the 6pin cable of the control board of the miner and connect it to the hash board tester. Power the hash board using the power cable that came with the miner. This mode does not require disassembly and allows the hash board to be tested individually.
2. IO data interface (20Pin)
This interface is suitable for earlier Avalon models.
3. IO data
IO interface model, suitable for Avalon models 1066pro 11 series and 12 series.
Avalon hash board tester interface
1. PC power interface (6Pin*2)
Please do not connect the original power supply to this interface; 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 simultaneously.
2. Footswitch connector
It is used to connect the footswitch; there is no need to trigger the test button manually, and the operation is simple.
3. Serial input port
The external serial port connector connects other brands of hash board tester motherboards, such as Antminer, Whatsminer, etc.
4. Select switch 1
Chip type selector 1
5. Select switch 2
Chip type selector 1
The ASIC chip model to be tested can be selected by flipping two sets of switches. If you are not sure about the ASIC model, you can find the silkscreened ASIC model on the edge of the hash board. The specific corresponding location is shown in the figure below.

6: USB (GOT) interface
They are used to connect to a computer or mobile phone to view test results quickly.

1. Status Indicator
Different colored lights represent different power states.
2. Measurement mode/test mode, select button
Used to select measurement mode and test mode, press to enter measurement mode, reset to enter test mode.
3. Original power mode test button
To test with raw power mode, please use this button as a trigger button.

Avalon hash board tester mode description:

1. PC power supply mode
This mode refers to the mode used under normal maintenance of the hash board. Remove the hash board and use another PSU to power the hash board tester for easy inspection and maintenance.
2. Original power mode
This mode means testing the whole miner without dismantling the miner and using the original miner power supply to power the hash board tester.
3. Measurement mode
This mode indicates that the hash board tester only sends a detection signal (about 0.9V) to the hash board and does not scan and test the hash board; that is, the alligator clip will not have a voltage output and is only used to detect the signal path of the hash board. Therefore, data such as core voltage, number of chips, and core temperature will not be automatically exported in this mode.
4. test mode
It means that the hash board tester sends a detection signal to the hash board and starts the test simultaneously. The alligator clip will have voltage output, and the hash board will run hot. In this mode, chip temperature, voltage, and the number of chips can be tested.

Avalon hash board tester test process:

Taking the test of the Avalon hash board A3201 chip as an example, the test process of the Avalon hash board tester in PC mode is explained in detail:
1. Power up the hash board tester, insert the footswitch, and connect the USB serial port to the computer if necessary;
2. Set the ASIC selection switch to the correct position;
3. The main output power supply is divided into positive and negative poles, respectively clamped to the hash board, red is the positive pole, and black is the negative pole;
(Please note that the data cable connection must be correct and firm. In severe cases, the hash board tester or the hash board may be burned out)
4. Connect the data cable to the hash board according to the type of hash board cable interface;
5. Do not release the footswitch; (the test mode and measurement mode are switched in the PC mode switch)
a. Test mode: 4 seconds after starting the test, there is main power output, and the power is automatically turned off after the test is completed. The test results will be fed back to the LED and serial port printing information;
b. Measurement mode: press down to generate the main output immediately, do not start the test program, release the power immediately; in this mode, when the power board is powered on, the C signal will always have data transmission, which is convenient for finding problems;
c. Original power supply method: This method is generally used for on-miner testing, using the original power cable without removing the power board. Insert the 6Pin connector of the original power supply into the hash board tester, insert the data cable into the hash board, turn on the power, and press the original power mode test switch to start the test. The test results are fed back to the LED and serial port to print information.
