Avalon Control Board for 1066pro, 1166pro, 1126, 1246, 1248, 1266 Miners
The Avalon Control Board is a direct replacement for faulty or degraded control boards in Canaan Avalon miners, covering the 1066pro, 1166pro, 1126, 1126pro, 1246, 1248, and 1266 models. The control board is the central nervous system of any Avalon miner — it manages hashboard communication, network connectivity, fan control, and firmware. When a control board fails, the entire miner goes offline. This replacement board is available with five chip model options (A3200, A3201, A3202, A3203, A3204) to match your specific Avalon miner generation.
Avalon Control Board Chip Model Compatibility: A3200–A3204
Different Avalon miner models require different control board chip versions. The A3200 through A3204 variants correspond to different hardware revisions across the 1066pro, 1166pro, 1126, 1246, 1248, and 1266 product lines. Selecting the correct chip model ensures proper hashboard initialization and stable operation. If you're unsure which chip model your miner requires, check the markings on the existing control board or contact our technical support team for identification assistance.

Avalon Miner Control Board Replacement: Troubleshooting Guide
Common symptoms of a failing Avalon control board include: miner not appearing on the network, hashboards detected but not hashing, fan speed stuck at 100%, and firmware update failures. Before replacing the control board, verify that the issue isn't caused by a bad ethernet cable, corrupted SD card, or power supply fault. If diagnosis confirms a control board failure, select the matching chip model (A3200–A3204) and swap the board. For newer Avalon models (A1346, A1446, A1466, A1566), see the Avalon A1566/A1366/A1346/A1446/A1466 Control Board. Manage multiple legacy Avalon units with the AUC3 Converter Card for Avalon 7/8/9 Series. Keep your mining operation quiet with the Avalon 120mm Replacement Fan.
