#Getting started with Acqua A5 and Berta dev boards

<abstract>
This article explains how to get started with Acqua A5 module using one of the Berta dev boards available
</abstract>

##What do you need to start ?

Acqua A5 is designed to be used on a carrier board. The following carriers are available
from the [Acme Systems eStore](/pricelist?category=acqua):

* [BERTA-A5-BASIC](/acqua#berta_a5_basic)
* [BERTA-A5-EXT](/acqua#berta_a5_ext) 

If you are using a custom designed board you need at least the following parts:

* An USB to 3.3 volt serial adapter like @product='DPI' or @product='USB-3V-SER'
* A bootable Linux microSD made from one of this images: [MicroSD images for Acqua](/download_acqua) 

##Getting started with BERTA-A5-EXT

Insert the Acqua A5 on the BERTA-A5-EXT carrier board:

Insert the bootable microSD inside the Acqua A5 microSD holder:

Insert the DPI adapter:

or alternatively the USB-3V-SER adapter:

Set the serial terminal configuration at: <b>115200.N,8,1</b> with no acknowledge

This is the debug port pinout

	| 1   | 2   | 3   | 4   | 5  | 6   |
	|-----|-----|-----|-----|----------|
	| -   | -   | TXD | RXD | -  | GND |

Plug the LAN cable. Acqua will search an active DCHP server on your LAN to get dynamically the IP address:

Plug the 5 volt power supply and check the bootstrap messages on the serial terminal:

In this phase is not so important to configure the dip switch near the mini USB connector
so you can leave it in the default configuration:

This is the dip switch meaning:

| 1   | 2   | 3   | 4   | Function |
|-----|-----|-----|-----|----------|
| ON  | ON  | OFF | OFF | USB A lines on J8 microUSB port. In this way it is possible to access to RomBOOT code using [SAM-BA](/SAM-BA) or use the Linux Kernel USB gadget drivers|
| OFF | OFF | ON  | ON  | USB A lines on WiFi module      |
