Description
ARC Whatsminer Hashboard Tester Pro
The ARC Whatsminer Hashboard Tester Pro is a professional-grade diagnostic tool designed specifically for testing and troubleshooting MicroBT Whatsminer hashboards. This dedicated tester allows ASIC repair technicians to quickly identify faulty chips, diagnose hashboard issues, and perform EEPROM operations without needing to fully assemble the miner, saving significant time and reducing diagnostic costs.
Key Features
- Chip-Level Diagnostics: Scan individual ASIC chips on the hashboard to identify which specific chips are failing, defective, or underperforming
- EEPROM Flashing: Read and write EEPROM data in under 30 seconds without connecting a computer or external programmer
- No Disassembly Required: Test hashboards without needing to remove them from a fully assembled miner chassis
- Quick Fault Identification: Pinpoint precise chip malfunctions and quantify the number of chip failures per hashboard
- Standalone Operation: Built-in display and controls for fully independent operation without a connected PC
Compatible Hardware
The ARC Whatsminer Hashboard Tester Pro supports MicroBT Whatsminer hashboards from multiple generations including:
- M20 Series: M20, M20S
- M30 Series: M30, M30S, M30S+, M30S++
- M50 Series: M50, M50S, M50S+
Why You Need This Tool
For professional ASIC repair operations, the ARC Whatsminer Hashboard Tester Pro is an essential diagnostic instrument. Without a dedicated tester, identifying a single bad chip on a hashboard with dozens of ASIC chips is a painstaking process of visual inspection and multimeter probing. This tester automates the process, scanning the entire hashboard in minutes and delivering a clear report of which chips need replacement.
The EEPROM flashing capability is equally valuable. Corrupted EEPROM data is a common cause of hashboard failures that can be resolved without any physical component replacement. Being able to read, backup, and reflash EEPROM data directly from the tester eliminates an entire category of repair complexity.
If you operate a mining repair business or manage a fleet of Whatsminer units, this tool pays for itself quickly by dramatically reducing diagnostic time per hashboard.
