LART development boards

KSB Development boards available

While the original LART board is no longer available from us, we have some KSB development boards, with User Guide and software, for the development of low-power, high-performance embedded Linux applications on ARM processors.

Specification

The 100x75mm LART boards have a 190MHz Intel StrongARM 1100 processor, 32MB of EDO RAM and 4MB of Flash RAM, and consume less than one watt to achieve about 200MIPS. The current version is revision 5.

The design was carried out at the Technical University of Delft, by Jan-Derk Bakker, and is released as Open Hardware at

http://www.lart.tudelft.nl

where more details can be found; we summarise them here.

The boards have a range of features that make them excellent for wearable computing, robotic control, process monitoring, compile farms, vehicle telematics, and all sorts of networked devices:

Very small size (7.5x10cm, 3x4")
Low power (0.6W typical), high performance (200MIPS) - the clock is scaleable to select your power/performance point.
Stackable design - expansion boards stack on the high speed bus connector
Wide input voltage range (4-10V or 4-16V)
Completely open hardware design so can't be locked in or left with unsupported equipment.
High and low speed buses for enormous expansion potential
Well-tested design
PSU can supply up to 16W to power additional devices.
DAC to control the CPU core voltage by software for maximum power savings. (This feature is new for rev5 LARTs)
Collaborative development environment with other LART users means that improved software is continuously available to all users, and you can talk direct to the hardware designers. Of course you don't have to run Linux on it....

The Flash RAM is sufficient for a bootloader, a compressed kernel and a compressed ramdisk, and Aleph One provides software to allow ARMLinux to boot from it.

Most of the signals from the SA-1100 appear at external connectors. One has the 32-bit Data bus and 26 Address lines, and can handle 400MB/s. Another handles most GP I/O pins and enough Data/ Address lines to implement peripherals based on PCMCIA or ISA standards, so that a simple device for a specific task can be attached, such as an LCD screen, or a PCB for robotics or process control.

A Serial connector provides a pair of RS232 links, and a JTAG connector allows the on-board Flash RAM to be loaded. The on-board power supply accepts 4 to 10V DC and can provide up to 16W to peripheral or attached boards.

The associated KSB board is also available. It plugs onto LART and provides:

Ethernet interface (new for rev2 KSB)
IDE/ATA interface (44 pins on 2mm centres)
Stereo 16-bit 44KHz audio output at line and headphone levels
Two PS/2 connectors for mouse and keyboard
Mono audio I/O fron a UCB 1200 chip
Connectors for IrDA, POTS, USB Client, LCD and touchscreen

This shows the LART and KSB connected together (behind) making a very small overall package. A LART alone is shown in front. The cable is a 2.5" IDE to 3.5" IDE adaptor cable for attaching a 3.5" IDE drive. A 2.5" IDE drive is just about the same size as LART+KSB.

PRICES

LART package costs GBP440, and KSB costs GBP218, and Ethernet (for rev1 KSB) costs GBP120 all including air postage. Add GBP35 for carriage by courier service rather than air post. These prices EXCLUDE British tax: in Britain add 17.5% VAT

We are happy to quote for your exact needs, if you say where the goods are to go.

The prices include:-

LART board with boot loader and kernel and ramdisk installed Power and Serial cables. JTAG connector to load kernels etc. Seven CDs of software, comprising kernels, ramdisks, and tools, with pdf and html documentation for the LART and KSB, as well as a full Debian-ARM 2.2r2 binary and source release with thousands of packages of useful software.
Guide to ARMLinux for developers on paper and CD ROM, published by Aleph One Ltd. This tells you everything you need to know about ARMLinux and LART even if you are unfamiliar with them.
The KSB is just a board, supplied plugged onto the LART
The Guide is also available separately at GBP38
An Extension cable, [25-way D male-to-female], is available for GBP12 to facilitate connection of the JTAG connector between the LART and a computer.
A Lattice Semiconductor cable for 'ispDownload' to the PLDs on KSB is available for GBP65 if bought at the same time as LART+KSB. Lattice Part Number pDS4102-DL2

Payment methods

Bank Transfer

Payment by Bank Transfer is preferred, made directly to HSBC Bank plc, City Office, PO Box 85, Cambridge, Sort Code 40-16-08, Account 7136 3697, for the account of Aleph One Ltd. Please ensure that (our) receiving Bank Charges are paid by you, and advise Aleph One if you make a payment this way.

Credit Card

Payment by MasterCard or VISA is acceptable, but we add 2.5% to your invoice to contribute to the charge we pay the Bank. No charge is made until the tested product has been despatched. See 'Security, Privacy and Terms of Sale', below, if you are concerned about sending your card number.

Purchase Orders

UK institutions can issue Purchase Orders, for payment 30 days from Invoice date.

EU customers who quote an EU Tax Number should ask for a precise Quotation specifying carriage by insured Post or Courier.

These goods are priced in GBP Sterling. As an approximate guide, One GBP is 1.5USD and 1.6 Euro, but these rates change daily.

Resources

Here are some lart resources, for those who already have boards, including precompiled blob, kernel and ramdisk binaries, CD errata and the development version of blob.

LART projects

LARTs are already being used in a range of projects. One of the most interesting the 'virtual statue' being developed at TU Delft by the LART team. They are creating a statue in the university grounds which can be seen by those wearing a pair of LARTs, one of which drives the virtual reality goggles on which the rendered statues image is displayed, and the other drives a GPS+intertial position and direction device which defines the viewpoint so that the correct image is displayed. Other processing is done on other LARTs over the network. This system allows the statue to change in real time and is a marvellous demonstration of what is possible with wearable computing.
