  • Page 18: Power Supply Configuration

    NuMaker-M071VG Power Supply Configuration The NuMaker-M071VG is able to adopt multiple power supplies. External power sources include NU1 Vin (7 V to 12 V), V (depending on the target chip operating voltage), and PC through USB connector. By using switches and voltage regulator, multiple power domains can be created on the NuMaker-M071VG.
