LDO powering domain voltage and signals on Antminer D7 hash board

The main power of the hash board is composed of domain powering circuit, LDO powering, and signal transmission, so this video will explain their working principle and measurement method on the Antminer D7 hash board. Only when the domain powering and LDO powering are normal, the ASIC chip can communicate normally, that is, signal transmission. After that, the entire hash board can function normally.
