The measurement frequency range of NanoVNA-F V2 is up to 3GHz. It is a product based on edy555's NanoVNA and OwOComm's S-A-A-V2. I will find a nicer way to handle it later. Chelegance NANOVNA-F V2 3 GHz Mini Vector Network Analyzer is a new generation of portable, stand-alone VNA, featuring a 4.3 inch IPS LCD screen, metal enclosure, 5000 mAh battery and SMA connectors. To put the file at the correct location, do the following. The different versions are commercialized overall for<100. Another way is to connect USB_DP to PA10 directly and use PA10 to control USB connect and disconnect.īecause edy555's ChibiOS/os/hal/ports/STM32/LLD/ADCv3/hal_adc_lld.c is not updated with ADCv3 protocol, I modified and name it as hal_adc_lld.c.fixed. The nanoVNA is an open-source project and extensive resources are available to reproduce it ( edy555 (TT), n.d., GitHub - hugen79, n.d., GitHub - NanoVNA, n.d. AT power-up, PA10 will pull down USB_DP then release to inform host a device is plugged in.

Also, the USB_DP pin has a 1.5K ohm pull up resistor connected to VDD (3.3V), and the USB_DP (PA12) is shorted with PA10. The current test board has the MCU STM32F072CBT6 replaced by STM32F303CCT6. Please refer to original NanoVNA page for detail preparation information.

For detail information, please refer to the original project page by edy555. The benefits are larger SRAM 40KB from 16KB, larger flash 256KB from 128KB, faster CPU clock 72MHz from 48MHz, and floating point accelerator. This is my attemp to port the STM32F303CCT6 to this popular NanoVNA project.
