Original control board for Bitmain Antminer 19 Series

Modern miners require reliable components that can ensure uninterrupted equipment operation and stable performance. The Bitmain Antminer (19 Series) control board is an original solution for restoring or upgrading S19 series devices, which allows you to extend the service life of the equipment and maintain a high hashrate in round-the-clock operation.

Purpose and compatibility with miners

This board is the main element of the miner, responsible for coordinating the work of all nodes of the device. It supports a wide range of models: S19, S19+, S19i, S19 Pro, T19, S19j, S19j Pro, S19j Pro+, S19 XP, L7, D7, K7, KA3, HS3, D9, DR7. Due to the versatility of the solution, this board is suitable for both air cooling and heavy-duty applications in industrial farms.

Setup instructions

When installing a new control board, we recommend that you immediately update it to the latest firmware. Two scenarios are possible:

1. S17 firmware is pre-installed – an update to S19 is required (online or via SD card). After the update, you need to restart the board and wait for the OTP function to be enabled. At this point, the power should not be turned off.
2. The S19j Pro firmware is preinstalled – online update to most models of the series is supported. If you need to return to a different firmware version, you must first roll back to S19j Pro and then update.

Important notes

• Premature power off during OTP activation will damage the U1 chip.
• The U1 chip, once OTP is enabled, cannot be reused in other models.
• Miners that have already activated OTP do not need to re-enable it.
