OpenMoko is a software distribution stack that sits on top of a hardware platform. The Neo FreeRunner phone is the second hardware platform to take advantage of OpenMoko. You can find specifics of the hardware by reviewing this introduction page and the pages in the category as shown at the bottom of this page.
NOTE: This page is about hardware that is currently in design/prototype phase, changes are frequent |
The main Processor (CPU) of the Neo1973 GTA02 is a Samsung S3C2442B B54 (running at 400 MHz)
256MB integrated Samsung NAND flash inside the 2442 multi-chip package, attached to the S3C2442 NAND controller
16MBit ST M58WR016KB706E NOR flash for 'unbrickable emergency boot' feature.
128MB SDRAM (64MB inside 2442 MCP, 1x Samsung K4M51323PC) attached to S3C2442 SDRAM controller
The GSM (including GPRS) modem is Texas Instruments Calypso based.
Unfortunately we cannot provide many details on the GSM chipset due to very tight NDAs. However, this is not neccessarily required, since it interfaces using a standard UART serial line with the S3C2442. On that interface, GSM 07.05, GSM 07.10 and other standardized protocols are used.

The Neo1973 has one microSD aka Transflash slot. It should support SDHC, and 4GB card has been tested. Anyone with 8GB card? MicroSD slot is under battery.
This is a 2.8" diagonal (1.7" x 2.27" - 43mm x 58mm) 480x640 toppoly (tpo) TD028TTEC1 module, using a Toshiba JBT6K74 TFT LCD Driver Chipset.
Delta DFBM-CS320 Class2 Module, using CSR BlueCore4
Accton (WLAN 802.11b/g SiP-M WM3236AQ(Flash Ver:2.0 Atheros AR6001GZ)
The USB Host controller is inside the S3C2442
The USB Device controller is inside the S3C2442
The I2C is a simple communication standard intended to move small amounts of data a few inches between chips.
Please see Neo I2C Devices for more information & a list of devices & the addresses currently in use & documented for the Neo1973.

There's a WM8753 Wolfson Microelectronics CODEC (This is not a 'smart' codec that can interpret MP3/... it is a simple dumb 'sound card'.
There's a National Semiconductor LM4853 Mono Amplifier at the analog audio output of the WM8753
There's a four-ring 2.5mm stereo jack which provides connectivity to old-fashioned wired headsets.
The headsets used by Motorola smartphones (A780,A1200, ...) and the V-360 have a compatible configuration.
This one is wired via PCM bus from the CSR Bluetooth chip to the Wolfson codec.
A Philips PCF50633 04 N3 is used for power management.
The Neo FreeRunner (GTA02) Battery is mechanically and electrically compatible with the Neo1973 GTA01 Battery, as well as limited compatibility with a Nokia BL5C battery. According to this post on the mailinglist. Photo of the battery inside the Neo1973.
The Neo1973 GTA02 features two buttons:

Information from [1].
Every hardware revision has its own u-boot image type. Thus, the bootloader has the revision hard-coded. The hardware revision is passed on to the kernel via the ATAG mechanism (ATAG_REVISION)
The kernel receives the ATAG_REVISION during bootup, and saves its contents in the "system_rev" global variable.
The kernel exports the system_rev variable in /proc/cpuinfo as "Revision :" line.
