Chennai, India-based E-con Systems announced a baseboard for its SODIMM-sized, Marvell PXA270-based processor module. The baseboard adds an LCD touchscreen, USB, serial ports, SDIO slot, and camera interfaces to the company's Linux-ready eSOM270 module, available in volume for about $75.

The new baseboard offers a 200-pin SODIMM connector for the eSOM270. The eSOM270 (pictured below, right) measures 2.63 x 1.22 x 0.15 inches (69 x 31 x 4mm), and comes pre-installed with Linux. It includes 64MB or 128MB of RAM, and is billed as a multi-purpose single-board computer (SBC).

The new baseboard for the eSOM270 is available with a choice of touchscreens. One option is a 3.5-inch QVGA (320×240) model. The other is a 5.7-inch model of unspecified resolution.

On-board I/O includes:

  • 2 x USB host ports
  • 1 x USB client interface
  • 3 x serial ports
  • SDIO interface
  • Camera interface

The baseboard ships with schematics, a user manual, and a bill of material (BOM), says E-con. The eSOM270 itself ships with a pre-installed, bootable Linux installation, and is also said to be compatible with Windows CE 6.0, via a BSP (board support package) originally targeted at E-con's PXA270-based Sirius reference design. The Sirius supports nine add-on modules, including WiFi, NFC, barcode reader, GPRS, GPS, quad UART, camera, fingerprint reader, and thermal printer, says the company.


E-con Systems did not provide pricing or availability information on the baseboard. The SOM itself costs $110 in quantities of 1K or above, for a 520MHz version that includes 128MB of RAM and 32MB of flash. Other versions can cost as little as $75, says E-con.
