“PicoBT is a professional miner tester that can diagnose and repair more than 70 hash boards and 19 miner power models such as Innosilicon, Whatsminer, Antminer, Aixin, and Cheetah. Compared with traditional miner testers, PicoBT tester has unique features that can reduce the diagnostic time on faulty small parts by at least 10 times and increase the accuracy of diagnosis by 4 times. In addition, it is a maintenance tool integrating the EEPROM editor and tester. Wide range of supported models:
• More than 70 hashboard models, including Antminer, Innosilicon, Whatsminer, etc.:

• EEPROM Flash and Editor:
Antminer (S11, 17 series) and Whatsminer hashboard. PicoBT tester product advantages:
• Models: Troubleshoot 70 hashboard models and 20 smart PSU models with just one universal tester and sync hashboard serial numbers.
• Speed and Accuracy: With the PicoBT tester, any hashboard damage and healthy chips can be detected 10 times faster; the detection speed is fast and accurate.
• PSU enabling: In addition to diagnosing failures with hashboards, this tester can troubleshoot more than 20 models of smart power supplies.
• EEPROM editor: It can synchronize the hashboards with different serial numbers inside the miner so that the serial numbers of all hashboards are consistent so that the mining machine can start and work normally. It is suitable for Antminer S9se, S9k, S11, 17 series, 19 series hashboards, and all Whatsminer hashboards. There is no need to connect a power supply to the hashboard, and no computer is required.
• Versatility: Ability to test hashes with different precisions and modes to detect weak chips in addition to healthy and broken ones. Additionally, the testing capabilities of the Smart PSU do not require any computer, making the PicoBT a unique universal tester. How to use the PicoBT tester:
First, connect the hashboard, power supply, and tester. The connection effect is as follows: Enter the hashboard tester mode, then press the on/off switch, and you will see the select hashboard page as shown below: This test takes the S17 hashboard as an example. After selecting the S17 option, press the white key to enter the S17 tester page. At this time, the page will display the name of the selected hashboard, as shown in the figure below: The thin blue line on the screen of Note2 indicates which interface of the tester must be used to connect to the selected hashboard. Note 3 represents the working methods of different keys. The specific key functions are as follows:
PSU: Press the PSU button to enable S17 PSU (APW9 with 19V, you need to use a PSU cable to connect the tester and PSU.
MOD: Select the test mode by pressing the MOD button. S17 has 2 test modes: Mode 1 and Mode 2.
ONE: If you toggle this button, it will change to 999. This means how many times you want to test the hashboard. Once or repeat 999 times.
PIC: If you toggle this button, it becomes PC0 and PC1. If PC0 is selected, the tester enables the PIC microcontroller in the hashboard, turns on the MOSFET in the hashboard, and makes the current flow into the hashboard. In this case, the RST signal remains at 0v in the hash board. If PC1 is selected, the PIC microcontroller in the hashboard will be enabled, but the RST signal will remain high (1.8v on the test point). If you choose PIC, it will turn off the MOSFET in the hashboard.
Note: If you select PC0 or PC1, test the hashboard with the 999 option; the PIC of the selected hashboard will turn on as long as you test it. Otherwise, PIC will be turned on and off for each test.
Back: If you press the back button, you will return to the page where you selected the hashboard.
TEST: After adjusting the PSU, MOD, and ONE options, you can press the TEST button to test the hashboard.
After testing the hashboard, you will see the following test results on the screen: Note 4 indicates how many times the tester has tested the hashboard;
Note 5 indicates how many chips the selected hashboard should have under healthy conditions;
Note 6 indicates how many healthy chips the tester has detected from the first ASIC to the front.
Note 7 indicates how many healthy chips the oscilloscope has detected from the last ASIC to the reverse signal test point of any chip connected by the oscilloscope probe.”
