● The inner multi-level and multi-group LDO combined with solid-state
capacitor, which can filter the superposed noise in the power supply. All the
circuit units are supplied by the low or ultra-low noise LDO without DC/DC
circuit to avoid high frequency switching noise. Even if using USB bus power
supply, it can also maintain the high quality for the internal power supply.
● With the external power supply port, convenient to upgrade the external
linear power supply. The device will auto-disconnect the USB bus power
