Firmware synchronization 1.2.43
Due to the discontinuation of NXP SA612A, we started to produce compatible chip ZeeTK NE602A, but due to the different chip manufacturing process, there is a slight difference between the two in the use of harmonics, new compatible ZeeTK NE602A NanoVNA-H rev3.7 and NanoVNA-H4 rev4.4 version hardware schematic. Using the SJWCH5351 (formerly SMC5351 renamed) as a signal source, it can operate down to 600 Hz. New hardware improves port isolation below 300 MHz.
NanoVNA-H-SI 2.8-inch NanoVNA-H using Si5351 as signal source
NanoVNA-H-MS 2.8-inch NanoVNA-H uses MS5351 as signal source, machine label hardware version MS ending
NanoVNA-H-ZK 2.8-inch NanoVNA-H using SJWCH5351 as signal source, machine label hardware version ZK or SM_ST ending
NanoVNA-H4-SI 4 inch NanoVNA-H4 using Si5351 as signal source
NanoVNA-H4-MS 4-inch NanoVNA-H4 using MS5351 as signal source, machine label hardware version MS ending
NanoVNA-H4-ZK 4-inch NanoVNA-H4 using SJWCH5351 as signal source, machine labeling hardware version ZK ending
Upload a revised version of nanoVNAsharp to be compatible with the new firmware. nanoVNAsharp has no features to update.
