Thanks all for your advices and valuable guidance , very informative .
Please did NANO-VNA H4 V4.3 has an STM32F407 microcontroler inside or STM32F10X ??
Did NANO-VNA H4 V4.3 has a reliable touchscreen function as it should or it's vary bugy ??
indeed i Have a NAno-VNA F , it run OK except very bugy touchscreen function especially when working over the menu, very desappointed and i would like to try this time an other Nano-VNA H4 V4.3 wich has approximatly the same features but no idea about it's touchscreen function reliability ?
if any known commun bugs still not resolved with Nano-VNA H4 V4.3 ??
