 # ESP32 w/ LED Matrix
 
+- ESP32 board (joy-it)
+- Simple 64x64 LED matrix
+
+This code requires a modified micropython with the
+added [ledmatrix library](https://github.com/Winkelkatze/ledmatrix).
+The compilation is not straightforward as it uses a modified
+I2S implementation that is a bit out of date.
