New firmware support 10k ~ 1.5GHz released, Click deepelec.com to get latest info.

NanoVNA-F is a product made by BH5HNU based on the Open Source Project of NanoVNA(https://ttrf.tk/kit/nanovna/). Thanks to hugen's creative idea to use harmonics output by Si5351, we designed NanoVNA-F to expand the measurement range to 1GHz, where S11 still has 40dB dynamic range at 1GHz.

1. Use 4.3-inch IPS TFT LCD & resistive touch screen, with a larger view angle and can be seen clearly outdoor.
2. Use large capacity 5000mAh/3.7V lithium battery, standby time is longer, and expand a USB interface. Usually, it can be used as a power bank when the instrument is not used.
3. The Lipo Charing IC to changed to IP5306(with 2A high charing current) , make the charging time shorter.
4. Use a larger and better operating level.
5. Support Chinese and English menu switching;
6. Upgrade the user program(firmware) by virtual U disk(16MB SPI Flash Memory Inside).
7. Standard aluminium case to protect SMA head and reduce the interference of external electromagnetic wave to instrument.
