Guide

The pins are labeled on both the bottom and top sides of the board, and organized into groups. Let’s look
closer at some of the pin groups:
Voltage Inputs
The pins labeled HV  , LV  , and two GND  ’s provide high and low voltage references to the board. Supplying
a steady, regulated voltage to both of these inputs is required.
The voltage supplied to the HV  and GND  inputs should be higher than that supplied to the LV  side. For
example, if you’re interfacing from 5V to 3.3V, the voltage on the HV  pin should be 5V, and the voltage on
LV  should be 3.3V.
