NanoVNA-F, FreeRTOS version of edy555's NanoVNA.
"VNA" means: 矢量网络分析仪器 / Vector Network Analyzer
项目描述 / Project Description
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 of use the harmonic of Si5351, We build NanoVNA-F and
expand the measure frequency up to 1GHz, which S11 still have 40dB dynamic range At 1GHz.
About NanoVNA-F machines Vendors and bad clones
Hello everyone, it is necessary to state that at present we only produce -F machines with metal case.
We do not resist enthusiasts buying machines from other suppliers, but enthusiasts need to have a certain discrimination ability: choose a supplier with good evaluation, and the price of the machine is trustworthy at around $ 120.
Like what hwalker in groups.io/nanovna-f said "be aware that some vendors are scammers and the only way to protect yourself is buying from a reputable source."
Recently we found a bad clone of the -F machine on AliExpress / eBay. We have open sourced all the code on github, but this clone is still badly made. ╮(╯▽╰)╭
As the picture shown below, We want enthusiasts to stay away from these crude products.
Please look for the product description in our shop, and think twice before purchasing any variant.
产品功能 / Product Features
NanoVNA-F hardware features include and are not limited to the following improvements:
- Use 4.3-inch IPS TFT LCD & resistive touch screen, with a larger view angle and can be seen clearly outdoor.
- 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.
- The Lipo Charing IC to changed to IP5306(with 2A high charing current) , make the charging time shorter.
- Use a larger and better operating level.
- Support Chinese and English menu switching;
- Upgrade the user program(firmware) by virtual U disk(16MB SPI Flash Memory Inside).
- Standard aluminium case to protect SMA head and reduce the interference of external electromagnetic wave to instrument.
