Electronic DIY LM317 Adjustable Voltage Regulated Kit DC Step-down Power Supply Making Parts With Case Soldering Assembly 220V

Product Features
1. 1.25-12V adjustable voltage regulator output, output current 200mA, suitable for powering small DIY circuits.
2. One adjustable signal generator output. It is convenient to provide pulse signal to the test circuit.
3. Logic pen function. It is convenient to test the logic level of the circuit.
4. With 1-way buzzer. You can test the continuity of the wire (connect the wire to the positive and signal input terminals of the power supply, the wire is connected – the buzzer will sound). You can also test low-frequency signals, (input the signal from the signal input terminal to 1, if there is a signal, the buzzer will sound)
