Bitmain Antminer BeagleBone Control Board + BraiinOS Firmware microSD card

Compatible with Antminer S19j and S19j Pro models

Model ID: S19j Pro Vers: 2.3 (BBLDTCS19JPRO2012)

This control board has a SD card slot in the back.

This board will replace S19j/S19j Pro AMLogic control boards that have a microUSB slot in the front, and allow for overclocking firmware such as Braiins, Asic.to, awesome miner, Vnish etc.

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. If you're not sure about this control board's or BraiinsOS+ compatibility with your miner, send us a picture of your miner model name sticker and PSU sticker. We can check compatibility for you.
