0-55MHz AD9850 modul DDS jelgenerátor rövidhullámú rádióhullámsáv HAM rádió SSB6.1 adó-vevő VFO SSB

0-55MHz AD9850 Module DDS Signal Generator Shortwave Radio Wave Band For HAM Radio SSB6.1 Transceiver VFO SSB
Features:
1. ENC image above coding switch feet, which, under the view of the switch of A contact pin 2 KB-2, and the drawing of B then KB-2 Pin 3, the drawing of continued on the KB-2 1 foot.
2. On the work mode and band control function:Due to the limited capacity of the microcontroller itself, drive, or external relay operating voltage is different, not directly drive a relay, drivers need to work mode and operating band needs an external drive circuit, a specific circuit can refer to other materials.
3. LCD backlight connection: Taking into account the number of people may use their own configuration LCD display, LED backlight may be because of different polarity, so the PCB, the 15 and 16 feet are vacant, and ask all of you to connect the LCD according to the polarity used.
4. It provides the LCD backlight connection, 16 feet grounded, 15 feet in series a 51 ohm resistor connected to 5V power supply is like, if you want to keep off the backlight, you can take a switch to 5V control.
5. If the LCD can not display the characters, please try to exchange PIC16F628A, because the two programs are different chips, follow my number marked on the component installation.
