Antenna Tune 128x32 Pixels ATU-100 Amateur Communication HF Hand -welded

Feature

* The finished package is a pure hand -welded, which provides a 3.2 program that supports the SSD1306 controller with a resolution of 128x32 pixels and a diagonal 0.91 -inch monochrome OLED display.

*This circuit contains a set of 7 inductors and 7 capacitors, which allows it to work in a wider frequency range, which can effectively cover the range of amateur radio range from 1.8MHz-50MHz.

* Optional functions include 1-5W opening, 10 seconds of screen self-extinguishing/Changliang, fully automatic/manual mode, etc. The default is 1W turning on, the screen is always bright, and the manual/automatic switching mode.

*DC socket connection power supply DC 10-15V is positive and external, the panel Power switch is in the open position, set the radio power at 5W-10W, long press the RESET/TUNE button, the device screen appears tune. Continuous power, the device can be adjusted automatically. Short press the RESET/TUNE button, and the device releases the previously adjusted LC relay, in a direct position.

*SX1308 is a fixed frequency. SOT23-6 closed current mode boost converter. The operating frequency of up to 1.2MHz enables the peripheral inductors to choose smaller specifications. The built-in soft startup function reduces the starting impact current. Internal integration of 80 milliligo power MOSFET, the maximum increase efficiency can reach 97%.

1*AUTOMATIC ANTENNA TUNER

Note：

1.The Ver1.21 version adds the SX1308 boost circuit to the motherboard space (this part of the component requires the player to buy it by themselves), which can be switched by the reserved SMT pad to realize the power supply method. And add AUTO fully automatic mode interface to the motherboard to facilitate everyone to perform DIY grinders. Note: The noise interference that may generate after adding this DC-DC booster circuit is not based on the basis of product quality problems.

2.The real color of the item may be slightly different from the pictures shown on website caused by many factors such as brightness of your monitor and light brightness.

3. Please allow slight manual measurement deviation for the data.
