Yes you can. Just add the code below to your website HTML. It will display a small widget showing the last six items you've listed:
<div class="depop-widget" data-username="your-username" data-width="300"></div>
<script defer="defer" src="http://assets0.depop.com/widget.js"></script>
Replace "your-username" with your actual Depop username.
For Wordpress.com users
Unfortunately if your blog is hosted on Wordpress.com you won't be able to use this widget as they don't allow iframes. You can read more here.
If your blog is hosted elsewhere - f.e. Wordpress.org - you will be able to use the widget.
