# Raspberry Pi and Blynk

{% hint style="warning" %}
This documentation is for the LEGACY version of Blynk platform which is no longer supported and will be shut down. 

You can sign up for the current version of Blynk platform [here](http://blynk.cloud/dashboard/register).

The new mobile apps can be downloaded from [App Store](https://apps.apple.com/us/app/blynk-iot/id1559317868) and [Google Play](https://play.google.com/store/apps/details?id=cloud.blynk\&hl=en\&gl=US).

The actual Blynk documentation is [here](https://docs.blynk.io/).
{% endhint %}

Blynk works with any model of Raspberry Pi **over WiFi / Ethernet**. 

**☝️We don't support BLE of Raspberry Pi 3 (yet)**

When writing apps on RPi, you can use Node.JS or C++.

Here are a few articles that may help:
