ESP32.LINKSTATION

linkstation.mp4

What it is and how it works

An All-in-One WiFi cryptomonitor to display cryptocurrency prices and also monitor one of your trades or investments, based on real-time quotes obtained via the freely accessible FTX.com markets API.

As the name suggests the project is focused on Chainlink. However, the code built on top of the Arduino framework is even for beginners easy to customize.
