Does anyone have a link to a schematic diagram for the HW version
4.3_MS of the NanoVNA-H4? My NanoVNA-H4 doesn't charge (no charge
light and no current flow) when connected to USB. I looked at the
board and its charging IC is an LN4056-H (labeled U2) but none of the
schematics I have found seem use this IC. I am having a hard time
diagnosing the issue without correct schematics. Are these newer
diagrams available publicly?
Thanks,
Kyle
