### 5.1 Main Board 10P Connect Header
### 5.1 Main Board 10P Connect Header & ICX301 Antenna Interface
On PM5's **main board** there is a **2x5P 2.54 mm Connect header** as a communication interface. This interface provides multiple breakout functions (used by peripherals such as the antenna), and its interface definition is as follows.

The following image shows the positional relationship between the 10P HEADER and ICX301 in detail.
And shows the signal definition of the 10P HEADER and the ICX301 interface.
> It is not completely accurate(position), may deviate due to welding precision issues. You will need to measure and confirm.
