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 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.

NanoVNA-F 迷你矢量网络分析仪是 BH5HNU 基于 NanoVNA 开源项目（ https://ttrf.tk/kit/nanovna/ ）开发的产品，射频部分和原版一致（NanoVNA-F 使用谐波扩展测量频率到 1GHz）。
NanoVNA-F 硬件功能包括并不限于如下改进：
1、使用 4.3寸 IPS TFT 液晶屏，视角更大，户外强光下也可以看的清楚；
2、换用大容量 5000mAh/3.7V 锂电池，待机时间更长，同时扩展出一个USB接口，平时不用仪器时可以当做充电宝使用；
3、换用大电流 2A 充电 IC，充满电时间更短；
4、换用更大的操作感更好的波轮；
5、换用更大的操作感更好的电源开关；
6、支持中英文菜单切换；
7、通过虚拟U盘方式升级用户程序；
8、标配铝制外壳，保护SMA头，减少外部电磁波对仪器的干扰；
9、软件开源 github.com/flyoob/NanoVNA-F
