Description
Bring your Antminer S19 back to full mining power with a genuine replacement hashboard from D-Central Technologies. Each board is professionally refurbished in our Canadian repair facility — inspected, repaired with genuine components, and tested under load before shipping. At a fraction of the cost of a new miner, a replacement hashboard restores the hashrate you are losing to a failed board.

Upgraded Through Refurbishment
D-Central’s refurbishment process is not just a wipe-down and rebox. Our technicians inspect every ASIC chip, solder joint, voltage regulator, and connector on the board. Any component that does not meet our standards is replaced with a genuine Bitmain part. The board is then run under sustained load to verify stable hashrate across all chips. This process often produces a more reliable board than a factory-new one, because every potential weak point has been proactively identified and addressed.
Cost-Effective Restoration
A single failed hashboard costs you roughly a third of your miner’s total output every day it goes unrepaired. A replacement board restores that lost hashrate at a fraction of the cost of buying a new S19. For home miners watching their operating margins, this is the most economical path back to full capacity.
Perfect for Loki and Slim Builds
S19 hashboards are the most popular choice for single-hashboard home mining builds. Combine one board with a Loki Kit, an APW PSU, and a D-Central Slim case or Space Heater enclosure, and you have a compact, quiet Bitcoin miner that doubles as a space heater during winter months. The S19 hashboard’s price point makes it one of the most accessible entry points into custom pleb mining rigs.

Frequently Asked Questions
Is this compatible with the S19 Pro or S19j Pro?
Hashboard compatibility within the S19 family varies by sub-model. While the S19 and S19 Pro both use BM1398 chips, the board layouts may differ. Contact our team to confirm compatibility with your specific miner model before ordering.
Can I build a complete miner from just hashboards?
Yes. With a single hashboard, a control board, a Loki Kit (or compatible PSU), and an enclosure, you can build a functional single-board miner. This is a popular approach for home miners who want lower noise and power consumption. D-Central carries all the components you need.
How long does the refurbishment process take?
Boards we sell are already refurbished and tested — they ship from our inventory. If you need a board repaired rather than buying a replacement, our repair service turnaround varies; contact us for current timelines.
What if the hashboard fails after I receive it?
D-Central provides a 7-day DOA warranty. If the board does not function upon arrival, contact us within 7 days for a replacement. Shipping costs for warranty returns are the customer’s responsibility.
Why Buy from D-Central?
D-Central Technologies has been the go-to ASIC repair shop in Canada since 2016. Every hashboard we sell is refurbished by the same technicians who handle our professional repair service — using the same tools, the same standards, and the same genuine parts. We stand behind every board because our reputation depends on it. Every hash counts.
