🧩Add-on to a repair, not a standalone item. We do not ship chips — the chip is installed on your board during the repair.
Every hashboard repair includes a set number of chip replacements; the number is shown on the repair page for that board. This add-on covers replacements beyond that number.

The final count is known only when the repair is complete.
