Introduction
The new Asuro xTend board provides multiple extension possibilities. The core is the very
powerful ATXMega micro-controller with 32KB Flash & 4KB SRAM running at 16MHz Clock with
low power consumption and several interrupt inputs.
The Asuro Robot has got new features with the Asuro xTend extension as following: extended
interfaces to the Asuro Robot, the improved Asuro Ext. BUS, a separate sensor extension
header, the LC-Display (2x8 Char) inclusive illumination control, 3 buttons, 4 status LEDs,
analogue inputs for SHARP distance sensors with power saving circuit, 2
nd
UART, and 2 ADC or
GPIO inputs are rounding up the package.
Simple and fast upload of the program code via USB interface the slow IR Interface is history (it
will be necessary just one more time to update the Asuro)!
Einfaches und schnelles Programmieren des xTend Bords über USB das langsame IR
Interface ist Geschichte (es wird nur noch einmal benötigt!
To preserve already make investments in existing add-ons, e.g. the Snake Vision ARX-SNK20,
Ultra-sonic ARX-ULT-10, Bluetooth Kit ARX-BT3, Wireless Kit ARX-WRL03, the interface signal
to the Asuro are kept and expanded. Software porting is simple due to the fact that the ATXMega
belongs to the same micro controller family from ATMEL.
From the Display ARX-DSP30 Kit you can use the display itself which will be connected to the
Asuro xTend board. The display interfaces directly to the micro-controller Atxmega32C4 and the
buttons and the trimmer for the display contrast are on the xTend board.
Sensor Module Extension:
- Asuro Compass-Gyro Module
Indoor Navigation supported by the new module. The 3D Magnetometer/Accelerometer
enables you to compute the heading (3D compass software is included)
Yaw rate of the 3D Gyro tells you how fast you are turning/drifting into a direction in
deg./sec. or detect if the Robot is blocked by obstacles.
- Asuro Baro-Temp-Humidity Module
With this extension the Robot knows barometric pressure / altitude (20cm sensor
accuracy) and the relative humidity and temperature.
- Asuro Real-Time-Clock Module
With this extension the Asuro knows time and date and can be woken up on a
programmed time.
There are many, many new options you can develop for your Asuro with the XTend Board be
creative!
