===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:

== Available options == === RS232/RS485/RS422 or CAN === === Male or female DB9 connector === == Connectors pinout ===
The following section describes the on-board connectors and their pinout.
==== Power supply ====
Power is provided through the JP2 DC Power Jack. Power voltage range is [12-24 V]
==== Lizard CPU module connectors – J1, J2 ====
J1 and J2 are the 140-pin mating connectors for Lizard CPU modulethe hosted SOM.
==== UART1 - J4 ====
J4 is a standard DB9 connector for the RS232 (4-wire) four-wires UART1 port. The following table reports the connector's pinout:

RS232 (4=== UART2/CAN -wire)RS485 (half-duplex)CANJ5 ===
Configuration Jumper J26 e J27J5 is a standard DB9 '''male''' connector for the configurable 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.
==== UART3 - J25 ====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.
