Is the Antminer L7 Control Board the Same as in the Antminer 19 Series?
Yes, it is. The S19’s have a few different flavors of control boards. Xilinx, BeagleBone, Amlogic. Pull your L7 out and take a look before you order.
Can I Put My 7007 Control Board from My L7 Straight into My S19 J Pro With HiveOS Or LuxOS on SD?
It needs to be flashed to S19j pro firmware before running custom firmware.
