Uses an LM2596S step down converter IC to create a regulated DC output. Hass solder pad connections for input and output, you will have to solder to this module.
Works from 4 VDC to 30 VDC and it has 1 volt drop so if you need 15 VDC you need at least 16 VDC.
The output voltage is adjustable from 1.25VDC to 28 VDC using a 10 turn trim pot.
The maximum output current is 3A, continuous and stable operating current of 2A or less is best.
The switching regulator has an operating frequency of 150 KHz.
Operating mode description
With off function to reduce power consumption.
Input and output voltages can be displayed alternately.
On/0ff output status, high level means output off, low level means output on. (note: high level (3.3v), the maximum output current 5mA)
