Description
The Innosilicon Test Board is a diagnostic test fixture designed for testing and troubleshooting Innosilicon hashboards outside the miner chassis. It replaces the control board during diagnostics, allowing you to power up individual hashboards, run test sequences, and identify faults without needing a fully assembled miner. If you repair Innosilicon miners or maintain a fleet of T2T or T3 series machines, this tool is essential.
When an Innosilicon miner goes down, the first question is always: which hashboard failed? Rather than swapping boards between machines or sending the entire unit for repair, the test board lets you isolate and test each hashboard independently on the bench. Connect the hashboard, power it up, and run diagnostics to identify dead chips, voltage rail issues, or communication faults. This is the same approach used by professional ASIC repair shops worldwide.
D-Central stocks the Innosilicon Test Board because we use it in our own repair facility. Innosilicon miners — particularly the T2T and T3 series — remain widely deployed, and hashboard failures are a common repair category. Having the right test fixture on hand is the difference between guessing and diagnosing.

Key Features
- Broad Innosilicon compatibility — supports the full T2T and T3 family including T2T, T2T+, T2TH, T2THF, T3, T3+, T3+ PRO, and many sub-variants.
- Standalone hashboard testing — test individual hashboards on the bench without assembling a complete miner. Isolate faulty boards quickly.
- Chip-level fault identification — when combined with diagnostic software and a multimeter, pinpoint which chips or voltage domains are failing on the hashboard.
- Professional repair tool — the same type of fixture used in commercial ASIC repair shops for Innosilicon hashboard diagnostics.
Frequently Asked Questions
Does this work with Antminer or Whatsminer hashboards?
No. This test fixture is specifically designed for Innosilicon hashboards. Bitmain Antminer and MicroBT Whatsminer hashboards use different connectors and communication protocols, and require their own model-specific test fixtures. D-Central carries test fixtures for other manufacturers as well.
Do I need a power supply to use this?
Yes. The test board requires a compatible power supply to provide the voltage rails that the hashboard needs during testing. The PSU is sold separately.
Can a home miner use this, or is it only for repair shops?
If you operate multiple Innosilicon miners and want to diagnose hashboard failures yourself rather than sending them for repair, this tool is for you. It does require some knowledge of hashboard diagnostics and electrical safety. For those who prefer professional service, D-Central’s ASIC repair team handles Innosilicon repairs in-house.
Why Buy from D-Central
D-Central has repaired Innosilicon miners since the T2T era. Our technicians know these boards inside and out, and the Innosilicon Test Board is standard equipment on our repair bench. When you buy diagnostic tools from D-Central, you are buying from a team that actually uses them professionally — not a reseller listing products they have never tested.
