Versatile waveform generator for DIY projects and testing: this ICL8038 function signal generator module can output sine, triangle, and square waves, providing flexible options for your experiments and builds. performance singlechip solution: powered by the ICL8038 IC, it delivers accurate waveform generation with minimal external components, requiring only a small number of resistors to produce clean sine, triangle, and square outputs. Clear wiring and polarity guidance: the resistors used are nonpolarized but may have different values; ensure correct resistor values and proper alignment of the positive and negative supply terminals during wiring. The PCB is clearly labeled to help you connect wires correctly. Easy and safe operation: the module runs from a 12V power supply and covers a frequency range of 50 Hz to 5 kHz. Frequency is adjustable via the included switch S, enabling convenient tuning for different tasks. Practical use scenarios: Test and characterize audio and signalprocessing circuits such as amplifiers and filters. Validate ADC/DAC interfaces and microcontroller input/output signals. Educational demonstrations of waveform generation and basic signal conditioning.
