like FIC is going to develop another device for OpenMoko quite soon, with the (code)name HXD8. On May 26th 2007 (GMT) Sean confirmed the existence of the device, said hardware support was almost done and cleverly told us to wait anxiously.
|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.|
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.

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.
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
Using same GSM modem on GTA01 and GTA02, TI Calypso with 850/1800/1900 configuration.
The HXD8 features either an SD, miniSD or microSD-card slot.
- Connected to: S3C2410 MMC/SD controller
- Driver: https://svn.openmoko.org/trunk/src/target/kernel/patches/s3c_mci.patch
LCD Module (LCM)
The HXD8 features a 480x272 pixel LCD (which is a widescreen (16:9) ratio) with PWM-controlled backlight.
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).

A Philips PCF50606 is used for power management.
HXD8 features an SPI-connected Marvell 8686 based WiFi module.
