Speculations: This article or section documents a device that is not yet confirmed formally and the device (if even released) may differ from the specifications given here. This page is based on well educated guesses, not facts.

It looks like FIC is going to develop another device for OpenMoko quite soon, with the (code)name HXD8. On May 26th (GMT) Sean confirmed the existence of the device, said hardware support was almost done and cleverly told us to wait anxiously.

According to this post the device is a networked collaborative automotive GPS unit, from http://dash.net/ .

Hardware

From the information found in the hardware documentation and kernel patches parts of the subversion repositories, the following specifications can be predicted.

Processor

According to https://svn.openmoko.org/trunk/src/target/kernel/patches/s3c2440-nand-disable-hwecc.patch the HXD8 will feature an S3C2440, capable of running up to 400MHz. The features are the same as the S3C2410 plus a camera interface.

Flash

According to a currently available hardware patch, the device supports 1 NAND Flash device of up to 4G. (uncertain about what kind of G that is. Could be 4Gb (which makes about 0,5GB), could be 4GB).

Some other patch implies that there is the possibility of connecting 3 NAND Flash chips.

RAM

128MB Random Access Memory, of which 2MB is used as a Framebuffer. https://svn.openmoko.org/trunk/src/target/u-boot/patches/uboot-hxd8.patch

GSM/GPRS

Not much info yet.

SD-Card

The HXD8 features either an SD, miniSD or microSD-card slot.

LCD Module (LCM)

The HXD8 features a 480x272 pixel LCD (which is a widescreen (16:9) ratio) with PWM-controlled backlight.

Camera

The Omnivision OM7670 Camerachip Image Sensor, is a low-voltage, low-power CMOS camera chip, capable of operating at 30fps on VGA resolution.

Light Sensor

The HXD8 features a light sensor by TAOS Inc. (Texas Advanced Optoelectronic Solutions). It's either a TLS2560 or a TLS2561. This light sensor will be included to measure ambient illuminance to control the LCM backlight illumination, or for exposure control for the camera (depends on location of the chip).

Power Management

A Philips PCF50606 is used for power management.

WiFi

Looks like the HXD8 features an SPI-connected WiFi chip.

GPS

The PMU chip's config contains a voltage group called GPS_3V3, and the gpio.txt a set of GPS UART data pins, which implies that there is a GPS chip available.
