# 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 **red** in the diagram below will be non-functional when using a Pix32 v6 FC on a Pix32 v5 Baseboard.
{% endhint %}
{% hint style="info" %}
Pin 1 starts from the flight controllers "Left side". All connectors are JST GH 1.25 mm Pitch unless noted otherwise.
