Measurement method for Avalon A821 hash board powering unit

If the Avalon A821 hash board cannot operate normally, the most important thing for us to troubleshoot is to measure whether the voltage of its powering unit is normal. For example, whether the main powering has 12V input, whether the input voltage of the LDO is about 3V, and so on. Here we will mainly demonstrate how to measure the voltage of the A821 hash board powering unit and the correct value of its voltage.
