    Innosilicon T1 hash board repair tutorial

    The hardware design of the Innosilicon T1 is the same as the DragonMint T1. This video tutorial mainly explains the powering process and signal transmission direction of the T1 hash board. The T1 hash board consists of 63 ASIC chips with a total of 21 voltage domains. Each voltage domain has a 1.8V LDO tube, and without 0.8V powering. The hash board has a total of 7 signals, CLK, START, RST, SCK, CS, SDI and SDO.

    Innosilicon T2 hash board repair tutorial basics

    Innosilicon T2 hash board is made up of 34 voltage domains in series, with a total of 68 T1558 ASIC chips. Un the Innosilicon T1 hash board, the T2 hash board does not have a step down circuit, and the power input voltage is directly transmitted to the No. 68 chip, and then transmitted back to the No. 1 chip in turn. On the T2 hash board, there are a total of 3 crystal oscillators, which are used to generate the CLK signal.

    Innosilicon T2TH+ hash board repair tutorial basics

    The Innosilicon T2TH+ hash board has a total of 140 ASIC chips, and every 4 chips are connected in parallel to form a voltage domain. The input voltage of the hash board is 17V, and the domain voltage of each domain is about 0.45V. It should be noted that each voltage domain has only one 1.8V LDO tube, and the 0.8V powering of each domain is provided by the built-in LDO of the ASIC chip.

    Innosilicon T1 main powering unit voltage measurement method

    How to correctly measure the voltage of the powering unit of the Innosilicon T1 hash board when the single board detection fails? The input voltage of the main powering is about 12V, the voltage value of the DC-DC step-down circuit is 9.9V, and the voltage value of each domain is 0.4V. Only when each voltage is normal, the signal can be transmitted normally, and the entire hash board can work normally.
  • Innosilicon T2TH+ hashboard main powering unit voltage measurement method

    Innosilicon T2TH+ hashboard main powering unit voltage measurement method

    How to measure the voltage of the Innosilicon T2TH+ hash board power supply unit? What is the voltage value of its powering unit? are the test points for each voltage? In this video we will explain the voltage value in detail and demonstrate its specific measurement method. When the voltage of the hash board is normal, the signal will be transmitted normally.
