- Page 2 This product is pure manual welding, providing 3.1 program support with SSD1306 controller, with a resolution of 128x32 pixels and a diagonal of 0.91 inch monochrome OLED display. This circuit contains a set of 7 inductors and 7 capacitors, which allows it to operate over a wider frequency range and effectively cover the amateur 1/7 radio range from 1.8MHz to 50MHz.
- Page 4 Note: The white object is 704 silicone, which is a fixed hollow inductor and magnetic ring inductor. Operating instructions The DC socket is connected to a power supply of 10-15V DC, with positive and negative voltage inside and outside. The POWER switch is in the open position, and the radio power is set to 5W-10W.
- Page 5 For the sake of environmental protection and energy conservation, this antenna tuner can sleep on the screen after 10 seconds of inactivity and no emission. At present, this antenna tuner work is in manual mode: the relay only adjusts after long pressing the RESET/TUNE button. This antenna tuner can also work in fully automatic mode: there is no need for a button.
- Page 6 The Ver1.21 version adds an SX1308 boost circuit in the spare position of the motherboard (these components need to be purchased by customers), which can be switched between power supply modes through reserved SMT pads. And add an Auto fully automatic mode interface on the motherboard to facilitate DIY grinding.
- Page 7 start function reduces the starting impulse current. Internally integrated 80 mΩ power MOSFET, with a maximum boost efficiency of 97%...
