# Pix32 v6 Baseboard Ports

{% hint style="warning" %}
**Pix32 v6** is compatible with **Pix32 v5** Baseboard and vice versa. 

\
Due to the difference in Pin map, the following ports shaded in <mark style="color:red;">**red**</mark> in the diagram below will be non-functional when using a Pix32 v6 FC on a Pix32 v5 Baseboard.
