If you’re not sure about the compatibility of this control board with your miner, please contact us through the chat bubble on the bottom right of the website. If you can share a picture of your miner model sticker label and PSU sticker label,  we can help check compatibility for you.

This listing includes a BraiinsOS microSD card bundled with the control board. This allows hassle-free turnkey autotuning/overclocking for Antminer S19J/J Pro models.
Just pop the SD card in to run BraiinsOS+, take it out to revert back to Bitmain Firmware.

BraiinsOS+ autotuning firmware helps improve efficiency and unlocks additional tuning options to get optimal performance from your mining machines.
