[VoltAmp Meter] : Combines two functions in one Current (A), Voltage (V)
[VoltAmp Meter] :It is miniature, accuracy, and more cost-effective. One digital meter can use as two, and save space and bring more economy for user.
[LM2596]: use solid capacitor, 36u thick circuit board, high Q value large ratio inductor, with output LED indicator.
[LM2596]:The positive input IN +, negative input IN-!The positive output OUT +, negative output OUT-!(The main input and output cannot be reversed, and the reverse may burn off.)
[LM2596]:Adopting 150KHz internal oscillation frequency, belonging to the second generation switching voltage regulator, low power consumption and efficiency.
