DC9V CW Morse Code Decoder Circuit Board Welding Practice DIY Electronic Manufacturing Kit_fgz

Features: 1. This CW Morse code decoder DIY kit is convenient for students and electronics enthusiasts to learn, understand, and practice Morse code. 2. It can recognize the dots (.), dashes (-), and intervals of Morse code and convert them into corresponding characters or numbers. 3. Supports CW audio signal input and displays the received Morse code. 4. Able to decode the received Morse code audio into characters and display the received bitrate. 5. Widely used in early wireless communication, Morse code was not only a communication method but also a hobby and challenge, a way to understand and learn telecommunications technology. Function: 1. CW audio signal input. 2. Display the received Morse code. 3. Decoding the received Morse code audio into characters. 4. Display the receiving bit rate. 5. External CW button for practicing Morse code transmission Parameter: Kit Name: CW Morse Code Decoder Power supply: DC9V power supply Working voltage: 9V Working current: 33mA PCB size: 101x50mm Operating instructions: (1) Connect to DC9V power supply. (2) The cw audio input terminal is connected to Morse code audio, which can decode and convert Morse code audio into characters, and display them on the LCD screen. (3) The cw audio output terminal can output received Morse code audio and can be connected to speakers or headphones. (4) Adjust the receiving threshold potentiometer to match the LED flashing frequency with the sound heard. If not adjusted properly, the decoder cannot decode the audio (5) Press the self-locking switch to view the entered Morse code, it will not display when it pops up. (6) Press the touch switch to view the bitrate of the received Morse code. (7) The CWKEY end is connected to the keypad, allowing for Morse code practice. The Morse code entered by pressing the keys will be displayed on the LCD screen. (Cannot be input simultaneously with audio input, otherwise it will interfere with each other and cannot be decoded correctly) (8) Short press the
