<p>I'm using a Raspberry Pi 3B (with 64GB card) and an external HD that contains the blocks. So far it works fine, CPU temp is around 57°C.
Syncing took a few days (2 or 3). I used the RaspiBlitz image + tutorial. This installs step by step your Bitcoin node and your Lightning wallet.

As it's hosted at my place and I want to have a public node, I also did port forwarding (n° 9735).</p>

<p>To use lightning you will need a Bitcoin full node.<br>
As hardware you can use:</p>

<ol>
<li>PC/Laptop</li>
<li>Dedicated Server(VPS Server)</li>
<li>Raspberry Pi 3(With external HD)</li>
<li>...</li>
</ol>

<p>If you want to use the Raspberry Pi 3 make sure to sync the Bitcoin blockchain on an external more powerful device and then move the blockchain to your Raspberry Pi 3 Harddrive. As Rene Pickard pointed out, the Raspberry Pi 3 is not so powerful and syncing there would take some time.</p>

<p>You can also try Neutrino(experimental) or use a remote full node and connect via rpc.</p>

<p>What is the hardware setup you use for your LN node? Is a Raspberry Pi 3 enough for testing and playing with small amount of funds?</p>

To use lightning you will need a Bitcoin full node.  
As hardware you can use:

1. PC/Laptop
2. Dedicated Server(VPS Server)
3. Raspberry Pi 3(With external HD)
4. ...

If you want to use the Raspberry Pi 3 make sure to sync the Bitcoin blockchain on an external more powerful device and then move the blockchain to your Raspberry Pi 3 Harddrive. As username_1 Pickard pointed out, the Raspberry Pi 3 is not so powerful and syncing there would take some time.

You can also try Neutrino(experimental) or use a remote full node and connect via rpc.
