The eZ80L92 Module requires a regulated external 3.3 VDC/0.5A power supply.
You may use a Low Dropout Regulator (LDO) to get 3.3 V from 5 V or use the fol-
lowing switcher circuit to generate 3.3 V from unregulated 10-28V power supply.
Power connections follow these conventional descriptions:
Figure 8 offers two typical power supply examples.
