===Introduction===
[[File:Dacu-top-view.png|600px|frameless|border]] Dacu is an ARM Cortex-A8 industrial tablet platform, built around a '''carrier board hosting ''' that can host various '''DAVE Embedded Systems''' SOMs, like, for example, the [[:Category:Lizard|Lizard]] CPU module. The main {{ImportantMessage|text=Please note that DACU supports several BOM variants in order to mate with different SOMs or evaluation boards.}}  Dacu's system specifications are the following:

Once J1 and J2 are the boot process has completed, you'll get 140-pin mating connectors for the default Android "desktop":hosted SOM.

Moreover, you'll have immediate access to the Android shell, so you can use the shell commands to interact with the system and see the output messages on J4 is a standard DB9 connector for the consoleRS232 four-wires UART1 port.

Once power has been applied, the system will boot loading the software components from the internal flash. Once the boot process has completed, you'll get the default Android "desktop":=== UART2/CAN - J5 ===
You can now access J5 is a standard DB9 '''male''' connector for the system using adbconfigurable UART/CAN port. The board provides some '''hardware''' mount options for the selection of the UART mode (RS232/RS422/RS485 with auto-direction) or the CAN mode. The board default configuration provides the CAN interface on this port, while the RS232/RS422/RS485 interface is provided as an option to customers who choose the alternative configuration.
Please note that this port can be used to connect a [http://www.rovingnetworks.com/products/RN240 Bluetooth serial adapter] powered by the 5V_BT signal.
