About the Product

Antminer L3+ L3++ D3 Control Board | Bitmain Replacement Motherboard

The Antminer L3+/L3++/D3 Control Board is a replacement motherboard for Bitmain's popular Scrypt (L3+, L3++) and X11 (D3) miners. When the original control board fails — causing network connectivity loss, hashboard detection errors, or fan control issues — this replacement board restores full miner functionality. The board weighs 0.3 kg and is built with standard PCB/PCBA construction. After installation, a firmware update is recommended to ensure optimal performance and compatibility with the latest mining software.

L3+ Control Board: Firmware Update After Replacement

A firmware update after control board replacement is critical for the L3+ and D3. The new board may ship with an older firmware version that doesn't match your hashboard configuration. Connect the miner to your network, access the web dashboard, and flash the latest official Bitmain firmware for your model (L3+, L3++, or D3). This ensures proper hashboard initialization, accurate temperature readings, and optimal fan curve behavior. The board is OEM as indicated in the original product specifications.

L3+ Miner Repair: Control Board + Power Supply + ASIC Tools

The control board is one of the most common replacement parts for aging L3+ miners. Pair it with the APW7 1800W PSU if your power supply also needs replacement. For hashboard-level repairs on the L3+, the BM1387/BM1397 Universal Tin Tool handles chip reballing across the entire S9/S17/S19 family. For newer Antminer control boards, see the L9 CV1835 Control Board or the Avalon A1566/A1466 Control Board.
