Main components
Processor
The main Processor (CPU) is a Samsung S3C2442B B54
Power Management
A NXP PCF50633 04 N3 is used for power management.
Flash
NAND Flash
256MB integrated into the Samsung S3C2442B B54
NOR Flash
16MBit ST M58WR016KB706E NOR flash for 'unbrickable emergency boot' feature.
SDRAM
- 64MB integrated into the Samsung S3C2442B B54
- 64MB from the Samsung K4M51323PC
- Total of 128MB
GSM/GPRS
The GSM (including GPRS) modem is Texas Instruments Calypso based.
- Connected to: S3C2442 UART1 (full-uart, RxD, TxD, CTS, RTS), /dev/ttySAC0 in userspace
- PM Driver: https://svn.openmoko.org/trunk/src/target/kernel/patches/gta01-power_control.patch
- Accessible GSM/GPRS antenna jack (if battery cover is removed) - MURATA MM8430-2610RB3 SMD RF TEST PORT. FOr compatible adapter see Murata part no. MXHS83QE3000
CALYPSO ASIC digital baseband
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 NDAd documentation for the calypso, register definition and hardware definition was leaked onto a public forum on the 4th of March by persons or persons unknown. The legality of reading these files may vary according to your local laws, as may generating code from them.
- Calypso D751992AZHH
- The firmware within GTA02 should be moko6 or later (internal code name)

Vibrator
- Driver: https://svn.openmoko.org/trunk/src/target/kernel/patches/gta01-vibrator.patch
- Connected to: S3C2442 GPIO
USB Host
The USB Host controller is inside the S3C2442
- Driver: Stock Linux kernel ohci_hcd
- USB version 1.1
- Supply USB 5v in Host mode using usb power switch AAT1275IRN-5.0-T1
- A net EN_USBHOST is controlled by PMU GPIO "GPO", this one signal when asserted (high)
- enables generation of 5V for external device using a charge pump
- enables connection of 15K pulldowns to D+ and D- to allow device insertion and removal detection for host mode
- DISABLES the path for USB power to charge the battery
It should also be possible to use host mode with externally-provided power. This will allow the FreeRunner to be connected to a USB device and be powered and charging the battery if present at the same time.
- Connect 0V, d+, d-, +5 to your USB device
- Connect a 15k ohm resistor between d+ and ground
- Connect a 15k ohm resistor between d- and ground
- Connect 0V, +5 to your >1A power source
- If your power source was not the Openmoko 1A charger, additionally connect a 47K ohm 5% resistor between the ID pin and ground to pretend to be the 1A charger.
In addition you need to make sure EN_USBHOST signal that enables the physical Host mode power generation and disables the USB -> PMU charging path is deasserted. This may be taken care of automatically shortly by detection of the 48K resistor on a USB insertion leading to forcing EN_USBHOST deasserted. The charge pump that generates the 5V in host mode doesn't seem to mind getting external 5V given to it, but the real issue is that the battery will not be charged at all if we leave EN_USBHOST asserted since one of its jobs is to stop that happening.
USB Device
The USB Device controller is inside the S3C2442
- Driver: https://svn.openmoko.org/trunk/src/target/kernel/patches/s3c2410_udc.patch
- Please see USB Product IDs on information about which Vendor/Product IDs we use
- 1200mAh lithium battery charges when connected to powered host.
- Mini-AB connector similar to this one.
I2C Devices
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.
Audio
See also: Neo1973 Audio Subsystem
Wolfson Codec
There's a WM8753 Wolfson Microelectronics CODEC (This is not a 'smart' codec that can interpret MP3/... it is a simple dumb 'sound card'.)
- Product Homepage: http://www.wolfsonmicro.com/products/WM8753/
- Data Sheet: WM8753.pdf
- Connected to: S3C2442 IIS interface (PCM data), S3C2442 I2C (Control)
- Driver: https://svn.openmoko.org/trunk/src/target/kernel/patches/asoc.patch
Mono Amplifier
There's a National Semiconductor LM4853 Mono Amplifier at the analog audio output of the WM8753
- Product Homepage: LM4853.html
- Data Sheet: LM4853.pdf
- Connects to (LM4853 pin):
- S3C2442 GPIO: HP_IN, AMP_SHUT (shutdown);
- Wolfson WM8753: LOUTL (LEFTIN), LOUTR (RIGHTIN);
- speaker4102: (LEFTOUT/BLTOUT-, BLTOUT+);
- headset-jack: ring 2 (RIGHTOUT), ring 3 (LEFTOUT/BLTOUT-) via 1uF-33R each

Case
The case for the FreeRunner is all black, as seen on the front page of the wiki.
Openmoko has released the CAD files for the case schematics for the Openmoko Neo1973 (GTA01) and Neo FreeRunner. These are available in the original Pro/E (.asm/.prt) format and alternative formats created from the originals.
We welcome your assistance in providing other formats. If you are able to convert CAD files from Pro/E format to other formats, please contact [3]. We are especially interested in the DXF format and in images rendered from these files.

Distinguishing hardware revisions
Inside the Bootloader
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)
Inside the Kernel
The kernel receives the ATAG_REVISION during bootup, and saves its contents in the "system_rev" global variable.
From Userspace
The kernel exports the system_rev variable in /proc/cpuinfo as "Revision :" line.
