Hashboard EEPROM Programming Cable for Antminer / Whatsminer Repair
This EEPROM programming cable is the professional decoding tool used in ASIC repair workshops to fix mixed-board errors and rewrite hashboard EEPROM data on Antminer and Whatsminer hashboards. The 2x9 18-pin USB interface with a built-in protocol decoding chip allows one-click EEPROM rewriting for mixed-board synchronisation across a wide range of Bitmain and MicroBT generations.
Two variants are stocked: one tuned for the Antminer protocol family, one for the Whatsminer protocol family. Pick the variant that matches the units you service most often — the cable selects the correct register map for that brand on plug-in.

Where the decoding cable fits in the repair workflow
The 2x9 18-pin connector seats directly into the hashboard's debug / programming header. The on-board FTDI FT232RL decoder translates between USB and the hashboard's proprietary register protocol, letting the technician rewrite the EEPROM contents — chip frequency map, board identifier, paired-chain data — to bring mixed or mis-flashed boards back into sync. Static-proof construction protects the ASIC chain during repeated bench cycles.

Common use cases
- Mixed-board error — chips from different chains synchronised after a swap
- EEPROM data corrupted after a bad firmware flash
- Recovered hashboard from a donor needing chain ID rewrite
- Bulk shop intake — re-flash a stack of refurbished boards to a clean baseline
- Workshop diagnostics — read board ID, chain map and chip frequency table
Frequently asked questions
Antminer variant vs Whatsminer variant — can I use one for both?
No. The variants are tuned for the respective protocol family. Pick the variant matching the units you service most often, or stock both for mixed shops.
Does it support the S9 or L3+?
No — S9 and L3+ are out of scope on this decoder. The supported Antminer line-up starts at the T17 / S17 generation.
What OS support does it have?
Windows 7 or newer, Linux Kernel 3.2 or newer. The FTDI FT232RL chipset is supported natively on both platforms.
Is the host software included?
The cable is the hardware interface. Use the standard repair-shop hashboard EEPROM utilities matching the Antminer or Whatsminer protocol family — contact us for guidance.
