Tiny ARM9 SBC runs Angstrom Linux
Mar 27, 2009 — by Eric Brown — from the LinuxDevices Archive — 7 viewsHark 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.

- Processor — Atmel AT91SAM9260 @ 200MHz
- Memory — 64MB SDRAM
- Flash — 256MB NAND flash for filesystem; 8MB data flash for bootstrap and kernel
