- Versatile waveform generator: This ICL8038 function signal generator module can output sine, triangular, and square waves, providing flexible options for DIY projects, testing, and experimentation. - High-performance chip: Based on a single ICL8038 IC, it delivers accurate sine, triangle, and square waves with a minimal set of external resistors, simplifying construction and improving reliability. - Wiring and polarity guidance: The resistance elements are non-polarized but may have different values. Proper identification and correct welding are essential, and ensure correct alignment of positive and negative terminals during wiring. - Easy and safe to use: The PCB is clearly labeled to help you connect wires correctly. Operating from 12V, it covers a frequency range of 50-5kHz. The included switch S provides straightforward frequency adjustments. - Assembly and welding guidance: Recommended soldering temperature is 320-380C. Use the proper order: start with low heat, small components before larger ones, and from inside to outside. Allow 3-5 seconds per joint to achieve a solid connection without overheating. - Key specifications: 12V supply; frequency range 50-5kHz; outputs sine, triangular, and square waves via ICL8038; clearly labeled PCB; non-polar resistance components. - Practical use scenarios: - Lab bench oscillator for testing filters, amplifiers, and audio circuits. - Signal source for microcontroller ADC/DAC experiments or PWM timing. - Educational demonstrations of waveform shaping and frequency response.
