Description
Hashboard Tester
This Hashboard tester is a direct replacement part for your ASIC miner.
The STASIC Hashboard MultiTester Pro is a professional-grade hashboard diagnostic tool built for ASIC repair technicians, mining farms, and serious hardware operators who need to identify faulty chips, test voltage rails, and verify board integrity — without powering up the entire miner. If you run a repair bench, this is the tool that separates guesswork from precision diagnostics. The Pro edition builds on the proven STASIC platform with the addition of the Avalon Finder 3.0 control unit, extending full diagnostic coverage to Canaan Avalon hashboards alongside the already comprehensive Antminer and Whatsminer support. With WiFi-based browser access, EEPROM programming, per-chip fault detection, temperature monitoring, and test hashing simulation capabilities, the MultiTester Pro handles the full diagnostic workflow for 45+ Antminer hashboard models, 28+ Whatsminer models, and the Avalon A10-A15 series. D-Central Technologies has repaired thousands of hashboards since 2016 in our Laval, Quebec repair facility. The STASIC MultiTester Pro is the same class of tool our own technicians rely on for board-level diagnostics. We stock it because we use it.Technical Specifications

Diagnostic Capabilities
The STASIC MultiTester Pro is not a simple continuity checker. It is a purpose-built hashboard diagnostic platform that performs chip-level analysis across the entire signal chain of a hashboard. Here is what it does: Per-Chip Fault DetectionThe tester scans every ASIC chip on the hashboard individually, identifying which chips are faulty and displaying their exact position on the board through the browser interface. Instead of guessing which chip is dead based on voltage drops or thermal imaging alone, you get a definitive map of serviceable vs. non-serviceable chips. This dramatically reduces diagnostic time and eliminates unnecessary rework. Voltage Monitoring and Chain Analysis
Monitors the voltage domain across the entire chip chain. The tester flags chips with voltage variance exceeding 90mV from nominal — a threshold that reliably indicates failing or marginal chips before they cascade into adjacent failures. You see the full voltage picture of the board in a single scan. Temperature Monitoring
Real-time temperature tracking per sensor during diagnostics. The tester maintains automatic power management to keep hashboard heating minimal during testing, so you can diagnose boards safely without the full thermal load of normal operation. EEPROM Programming
Read, write, and update hashboard EEPROM firmware directly from the tester interface. This is essential for board recovery after firmware corruption, serial number management, and preparing replacement hashboards for deployment. Test Hashing Simulation
With an external bench power supply (12-14V, 25-75A), the MultiTester Pro can run actual hash calculations on individual hashboards — verifying not just that chips respond to diagnostics, but that they can perform real SHA-256 work at adjustable frequencies. This is the definitive test before declaring a board repaired. Available for Antminer 17/19/21 series and L7/DG1. Chip Initialization
The Antminer+ diagnostic module provides chip initialization and hash test functions for the 17, 19, and 21 series as well as L7 and DG1 hashboards. Initialize chips, run frequency sweeps, and verify stable operation at target clock speeds.
The Avalon Finder 3.0 — Pro Exclusive
The key differentiator of the Pro edition is the Avalon Finder 3.0 control unit — a dedicated hardware module that extends full diagnostic coverage to Canaan Avalon hashboards. This is not a software unlock; it is a separate piece of hardware that connects to the tester via a dedicated data cable. The Finder 3.0 supports the full Avalon lineup from the A10 through A15 series. Given that Avalon miners use a fundamentally different communication protocol than Antminer or Whatsminer boards, this dedicated module is the only way to get chip-level diagnostics on Avalon hardware with the STASIC platform. If you service Avalon miners in any volume, the Pro edition is the only option. If your repair bench is exclusively Antminer and Whatsminer, the BASIC edition covers those families.WiFi-Based Browser Interface
The MultiTester Pro operates entirely through a browser-based interface — no proprietary software installation required. Power on the tester, connect to its WiFi hotspot (default network: “Tester123”, password: “stasictester”), and navigate to 5.5.5.5/menu in any browser. From there, select the hashboard model you are testing and the tester configures itself automatically. The WiFi interface is a local hotspot — it does not require or use internet connectivity. This means you can operate it in any workshop, on-site at a mining farm, or in the field without worrying about network availability. Diagnostic results display in real time in the browser, showing chip maps, voltage readings, temperature data, and fault locations.What Is Included

Who This Tool Is For
ASIC Repair ShopsIf you are running a repair bench — whether it is a one-person operation or a team — the MultiTester Pro replaces hours of manual probing with a single scan. Identify the exact faulty chips, verify repairs, and confirm boards are fully functional before shipping them back. The ROI on a single complex repair can justify the tool cost. Mining Farm Operators
Farms with hundreds or thousands of machines need to diagnose hashboards quickly to minimize downtime. The MultiTester Pro lets your on-site maintenance team triage boards without sending them out for repair. Good boards go back into production immediately; bad boards get flagged with specific chip-level fault data for your repair vendor. Independent Technicians
Building an ASIC repair business? The MultiTester Pro is the diagnostic backbone you need. It covers every major manufacturer, travels easily (680g), and the WiFi interface means you can use it on-site at customer locations with just a laptop or phone. Mining Hardware Resellers
Verify hashboard integrity before listing used miners for sale. A clean MultiTester report is the strongest quality assurance you can offer buyers, and it protects you from warranty claims on boards that were marginal at the time of sale.
Frequently Asked Questions
What is the difference between the STASIC MultiTester Pro and the BASIC edition?
The Pro edition includes the Avalon Finder 3.0 control unit — a dedicated hardware module that enables full diagnostic coverage for Canaan Avalon hashboards (A10 through A15 series). It also comes with all the Avalon-specific data cables and adapters. The BASIC edition covers Antminer, Whatsminer, Innosilicon, IceRiver, Goldshell, and other manufacturers but does not support Avalon boards. If you service Avalon miners, the Pro is the only option. If your work is exclusively Antminer and Whatsminer, the BASIC covers those families.
Do I need a bench power supply to use the MultiTester Pro?
For basic chip-level diagnostics (fault detection, voltage monitoring, EEPROM operations), the tester runs entirely on its USB 5V/2A power cord — no bench supply needed. However, for test hashing simulation (running actual SHA-256 calculations on the hashboard) and Avalon hashboard diagnostics, you need a 12-14V bench power supply rated for 25-75A (50A minimum for Avalon). The bench PSU powers the hashboard under test, not the tester itself.
Does the MultiTester Pro require internet connectivity?
No. The tester creates its own WiFi hotspot. You connect your laptop, tablet, or phone to the hotspot and access the diagnostic interface through a browser at 5.5.5.5/menu. No internet connection is required at any point during operation. This makes it fully portable — you can use it in any workshop, warehouse, or remote mining site.
How does chip-level fault detection work?
The tester communicates with each ASIC chip on the hashboard sequentially through the data cable. It checks each chip’s response, voltage domain, and (with a bench PSU) ability to perform hash calculations. Faulty chips are identified by position and displayed on a board map in the browser interface, along with diagnostic data showing what specifically failed — no response, voltage out of range, hash errors, or temperature anomalies. This gives you the exact chips to replace or reball rather than guessing.
What is EEPROM programming used for?
EEPROM (Electrically Erasable Programmable Read-Only Memory) stores the hashboard’s firmware configuration, serial number, and operational parameters. The MultiTester Pro can read, write, and update this firmware. Common use cases include recovering boards with corrupted firmware, updating hashboard firmware during repairs, cloning configuration from a known-good board, and managing serial numbers when replacing hashboards in a miner chassis.
How often does the firmware get updated, and what does the subscription cover?
The included 1-year firmware subscription provides updates as new miner models are released to the market. When Bitmain launches a new Antminer generation or MicroBT releases new Whatsminer models, STASIC pushes firmware updates that add support for those new hashboards. After the first year, you can renew the subscription to continue receiving updates. The tester itself continues to work indefinitely — the subscription only covers access to new model additions and feature improvements.
Can I test hashboards from different manufacturers with the same tester?
Yes. The MultiTester Pro includes data cables and adapters for Antminer, Whatsminer, Innosilicon, and Avalon hashboards. You select the manufacturer and model from the browser interface at 5.5.5.5/menu, connect the appropriate data cable, and the tester configures itself for that specific hashboard type. Switching between manufacturers takes seconds.
