3.[High-quality accessories] Use high-quality brand SMD capacitors, C-channel capacitors, use high-quality 1000V high-voltage SMD capacitors, and the PIC chip imported.
4.[Interesting assembly] The kit has already soldered components and chips, and will be equipped with installation instructions, which is easy to install and enjoy the fun of assembly.
5.[UHF connector] UHF connector is specially prepared for you, which provides an extra layer of guarantee and possibility for you to connect products and equipment.
The latest firmware version is 3.2：
SWR greater than 1.1 will automatically activate tuning, and the minimum power has been changed from 5W to 1W. 3.2 Program can be tuned below 5W. However, Too low value may result in insufficiently fine tuning (original default is greater than 5W auto tuning) , please know before placing an order.
Timeout for display reset increased to 2 seconds. This is required for some OLED displays with a very chain on the reset pin.

-1 x Automatic Antenna Tuner Kits
Contains the following items:
1.PCB board * 1 (SMD electronic components on the front and back have been soldered, and the latest version of the firmware has been burned)
2.Several plug-in electronic components and accessories(User welding is required)
3.0.96 inch OLED screen * 1
4.UHF-KF female connectors * 2 (also named SO239/SL16/PL259)
1.Insufficient tuning may occur within 5W. So do not try to be lower than 5W.
2.Recommended maximum power while tuning not above 30 watts. (after tuning you can set 100 watts and work on this power，Otherwise it will burn easily)
3.The product is DIY kits need to have welding ability.If you use a mobile power supply or a computer USB port to output power, you cannot start the ATU-100 because their voltage is too low.)
