Step Down + Khadas LPS cable

Hi,

Is there any problem to use this step down converter?

My psu is 12v.

I have a Khadas LPS cable, thinking to supply a Tone 2 maker board via I2S port.

The converter can handle 24w (3.4A with 5V).

Is it possible?

Thank you!

Hi，
You can use DC-DC module to convert from 12V to 5V, but I am not sure if the module showing is a DC-DC module or if it can convert from 12V to 5V. I suggest you can do these steps below to ensure it.

  1. Connect IN+ and IN- to your PSU, pay attention to the polarity;
  2. Then use a digital multi-meter to measure the voltage between these two points, to ensure if it is 5V

If the voltage you measure is 5V, you can use our LPS cable to connect to this module, and power for Tone2 or Tone2 Pro.
