Portable Signal and PWM Generator with Builtin 1000mAH Battery Key benefits Portable, independent signal source for field work and bench testing. Builtin 1000mAH battery allows untethered operation without constant USB power. Generates multiple waveform types including rectangular, sine, and triangular waves plus PWM output. Reduces the need for several separate devices. Adjustable output parameters let you tailor signals to drive circuits, test modules, or control processes that require precise timing or modulation. USB 5V charging and power compatibility ensures easy recharging from common power banks, USB chargers, or computer USB ports. Compact and user friendly design minimizes setup time and clutter while delivering consistent, repeatable waveforms. Primary functions and performance Waveform generation: rectangular, sine, and triangular wave outputs for general signal testing and modulation tasks. PWM generation: adjustable pulse width modulation for driving motors, LEDs, and control inputs requiring duty cycle control. Power: builtin 1000mAH rechargeable battery for mobile use; USB 5V input for charging and continuous operation from standard USB power sources. Controls: adjustable settings for waveform selection and PWM parameters to match a wide range of electronic and control requirements. Compatibility and use Works with devices and circuits that accept lowvoltage waveform or PWM inputs, including microcontrollers, driver modules, sensors, and test equipment. Compatible with standard 5V USB power sources for charging and powered operation. Practical applications Electronics prototyping and testing: provide stable sine, triangular, or rectangular signals when designing or debugging analog and digital circuits. Motor and lighting control: use PWM output to test motor speed control, LED dimming circuits, or PWMdriven power stages. Smallscale melting and quenching control: use adjustable waveform or PWM timing to support heating and quenching steps in hobbyist metalworking and jewelry work where controlled modulation of power or timing is required. What makes this product stand out Integrated battery plus USB 5V compatibility gives both mobility and the option for continuous powered use without interruptions. Multiple waveform types and PWM in one compact unit simplify testing workflows and reduce equipment needs. Straightforward controls and reliable output make the unit suitable for engineers, hobbyists, technicians, and students. What to expect in everyday use Quick setup: connect to your circuit, select waveform type, and adjust PWM or waveform parameters. Portable testing: run shortduration tests away from a bench thanks to the internal 1000mAH battery, then recharge via USB. Consistent signals: repeatable waveform outputs for comparative testing and iterative prototyping. Note Designed as a signal and PWM generator for electronic and smallscale process control applications. Ensure the output levels and power handling match the requirements of the connected equipment before use.
