NanoVNA-H4 Upgarding:

·    4-inch full-angle LCD screen, with DC dimming added, can be seen more clearly when using outdoors, and it is more comfortable to use indoors

·    Optimized the bridge to make full use of the Si5351 harmonics, now it can be measured to 1.5Ghz when using 5 times harmonics

·    When using the fundamental wave, the CH0 output level is raised to 0dBm, and the reflection measurement is more accurate

·    Resolve previous anomalies of NanoVNA-H near 6MHz

·    Reproduce the designed power management circuit to further reduce power noise, reduce USB power interference, reduce charging current, and protect the battery

·    Optimized PCB layout with capacity of 1950mAh battery for more than 8 hours using

·    Reserve UART interface for DIY extension

·    New ABS shell is made by mold opening, which is light and convenient and protects the machine
