Overview
This A113D control board is offered as a replacement for a failed control board in compatible Bitmain Antminer equipment. The supplied reference directly lists S21Pro, S21Pro+, S21+, S21XP, S21++ and L11 compatibility and identifies an Amlogic A113D main control chip with a micro USB data interface.
Check the model selection, screen requirement, connector layout and mounting arrangement against the board being replaced. The supplied material contains conflicting revision references, so a single board revision cannot be promised across every variation. Firmware and configuration-transfer requirements are also not published.
The listing is for one control board in the selected configuration. Installation requires the miner to be powered down and appropriate electrostatic-discharge precautions. Warranty depends on the logo selection: the supplied source states 150 days from shipment for boards with a logo and no warranty for boards without a logo.

FAQs
Which miners are directly listed as compatible with this control board?
The supplied product material directly lists Bitmain Antminer S21Pro, S21Pro+, S21+, S21XP, S21++ and L11 models. Compatibility with unlisted miners is not established.
How do I choose the correct variation?
Select the exact miner model first, then choose whether the board should have a logo and whether a screen is required. Compare the source image, connectors and mounting layout with the existing board before ordering.
What chipset and data interface does the board use?
The supplied product description identifies an Amlogic A113D main control chip and a micro USB data interface.
Is the board revision confirmed?
No single revision is published for every offered configuration. The page describes a CBE V2.0 board but also contains an A113D-related customer exchange mentioning a CB1 version 1.0 board, so the exact revision should be checked before purchase.
Does the board include firmware or installation programming?
The supplied material does not specify a firmware version, included firmware, configuration-transfer service or programming procedure. Confirm those requirements before installation if the existing miner configuration cannot be recovered.
What warranty applies to each logo option?
The supplied source states that boards with a logo have a 150-day warranty calculated from shipment. Boards without a logo are stated to have no warranty.
