LUBASS K1 Multi-Function ASIC Hashboard Tester – Antminer / Whatsminer

LUBASS K1 Multi-Function ASIC Hashboard Tester – Universal Antminer / Whatsminer Auto-Test with EEPROM Read/Write, Fan Test & Temperature Scan

The LUBASS K1 is a multi-function ASIC hashboard tester built for the bench of any serious mining-repair workshop. It supports all current Antminer and Whatsminer hashboards, with online firmware updates that add support for new miner models as they release — one-button automatic testing with hot-swap ribbon cables, EEPROM read/write for board backup and cloning, multi-point temperature scanning, fan-speed testing, and flexible 12–24 VDC / USB power-bank supply. The K1 you buy today keeps working on the miners you'll be repairing next year.

Multi-Brand, Multi-Model Support — All Current Antminer + Whatsminer

The K1 is designed for the reality of a modern repair bench where you handle both Bitmain and MicroBT boards on the same day. It covers all current Antminer models and all current Whatsminer models from a single unit, so a technician does not need to swap between OEM-specific test fixtures for every job. Selection is one press on the front panel — after that, the tester runs unattended across boards of the selected model.

One-Button Auto-Test with Hot-Swap

Push the button once to enter the target model's test mode, then plug boards in and out with the ribbon cable — the K1 auto-tests every new board without a return-to-menu step. There is no "press to start next", no re-selection, no menu navigation between jobs. The result: a bench technician can flow through a stack of hashboards several times faster than with a menu-driven fixture, which is the difference between finishing an urgent fleet repair the same day and pushing it to tomorrow.

EEPROM Read/Write for Hashboard Repair & Cloning

The K1 reads and writes hashboard EEPROM files fast. Two workflows benefit directly: (1) backup before repair — save the EEPROM of a working board before any invasive work, so nothing is lost if the chip gets zapped during rework; (2) board matching / cloning — read the EEPROM you need from a donor and write it into a target hashboard so the board runs cleanly. Read and write cycles are quick, which matters when you are stepping through a full fleet.

Fan Testing + Multi-Point Temperature Scan

The K1 doubles as a fan tester — connect a fan and read its RPM, quick-plug interface to move through a set of fans rapidly. On the hashboard side, the tester performs a multi-point temperature scan, reading the on-board thermal sensors so you can see thermal profile issues alongside the chip-scan results, rather than diagnosing them separately.

Flexible Power — Power Bank, 12–24 VDC

The K1 accepts 12 V to 24 V DC input and works from a USB power bank — an underrated feature when a repair bench does not have a spare regulated bench supply free, or when a technician needs to test hashboards in a rack aisle away from the main power point. The included 30 V adjustable supply and 5 V charger cover both stationary and mobile workflows.

Online Firmware Updates — Future-Proof for Upcoming Miner Models

The K1 supports independent authenticated online firmware upgrades from the manufacturer's site (lubass.com). Every current Antminer and Whatsminer model is covered out of the box, and each new firmware release adds support for upcoming Antminer and Whatsminer models as they are released — so the tester is not locked to today's lineup. A fixture that supported only the models available at purchase would be obsolete within a year; the K1's upgrade path extends its useful life across generations of Antminer and Whatsminer hardware.
