Tiny ARM9 SBC runs Angstrom Linux

Mar 27, 2009 — by Eric Brown — from the LinuxDevices Archive

Hark Technologies announced a 2.4 x 4-inch ARM9 single-board computer (SBC) that runs Angstrom Linux. The LE-9260 incorporates an Atmel AT91SAM9260 processor clocked to 200MHz, features a “fully accessible” 32-bit expansion bus, and ships with an optional baseboard, says the Summerville, South Carolina-based company.

Built around Atmel's popular, low-cost AT91SAM9260 processor, with 64MB of SDRAM, 256MB of NAND flash, and 8MB of data flash, the LE-9260 module operates as a stand-alone board, or can be mounted to a baseboard, such as the optional Hark model. In the latter case, the address bus, the full 32-bit data bus, and all I/O pins are available, and the built-in Ethernet port, COM port, mini-USB connection, and power connectors can be mapped to the baseboard, says Hark. The SBC includes a header for a DB-9 serial port, and the mini-USB connection can be used for updating the bootloader and kernel, says the company.

The optional baseboard is said to offer four DB-9 serial ports, plus a fifth DB-9 port dedicated to console duty. Additional baseboard features include an SD card slot, dual USB host ports, a Multitech modem socket, and optional Power-over-Ethernet (PoE) support.

Specifications listed for the LE-9260 include:

  • Processor — Atmel AT91SAM9260 @ 200MHz
  • Memory — 64MB SDRAM
  • Flash — 256MB NAND flash for filesystem; 8MB data flash for bootstrap and kernel
  • Bus — 32-bit data bus
  • Networking — 1 x 10/100 Ethernet with RJ-45 jack
  • USB — Mini USB-B connector for programming
  • Debug — JTAG Interface; debug RS-232 header
  • Other features — real-time clock
  • Power — 5-12 VDC jack
  • Dimensions — 2.4 x 4.0 inches
  • Operating system — Angstrom Linux (at91-20080528); Linux 2.6.27; UBoot; OpenEmbedded extensions

Availability

The LE-9260 appears to be available now. The board is priced at $300, and the optional development baseboard costs $350, says Hark Technologies.
