Power Supply Adapter

In stock

A power supply adapter that can sit on top of one of the clip adapters.

Each board is made to order so it may take me week or so to ship them, depending on how long it takes me to get the parts.

The clip adapters are all designed to work with the FlashcatUSB xPort 1.X made by EmbeddedComputers.

Using a 2A USB phone charger it can provide around 2A at 3.3V or 2A at 0.75-3V.

Comes with:

  • PCB
  • 4x 3-Pin 2.54mm Female Pin Sockets
  • 2.54mm Terminal Block
  • 2.54mm Jumper
  • 7x 2.54mm Pin Headers

You can power it using either a USB phone charger or some other 5v power source.

It can supply 2A at 3.3V or 0.75-3V. You can use a jumper to switch between either a fixed 3.3v output or a variable output from 0.75-3V which you adjust with a trimmer potentiometer. Using the switch you can bypass the voltage regulator and pass thru the 5V from either the USB port or your 5v power source.

The power supply has output pin headers so it can be used on its own, in case you want to use it with other projects.

There is a footprint for an optional input capacitor that you can install if it is needed for your particular setup, it uses a capacitor with 3.5mm lead spacing and an 8mm diameter like this one.

Make sure to change the voltage before connecting anything to it to prevent damaging whatever you connect to it. When using it with the FlashcatUSB xPort use only the same voltage as it, so either 3.3v or 5v.
