Hi Res Pictures of the Jetbook

[gr8npwrfl]

I will be opening my Jetbook and taking a series of pictures of the inside of the Jetbook.

I also have a high resolution camera on a microscope so I can take closeup pictures of anything anyone else needs.

If other people are are interested in these photos I will be able to post them to rapidshare.com or hotfile.com

I am looking at the system to do a hardware layout in preparation for possibly doing custom firmware for the Jetbook.

I would like to pool information with others out there.

Since I already disassembled the jetBook, you might check that thread for some instructions. It's easy enough to figure out, though.

Not unlike taking apart and IPOD. I guess its just the engineer in me

First here are the pictures

This is the parts list and what the parts are

With the following specs

ARM920T Microprocessor Core
AHB to IP Bus Interfaces (AIPIs)
External Interface Module (EIM)
SDRAM Controller (SDRAMC)
DPLL Clock and Power Control Module
Two Universal Asynchronous Receiver/Transmitters (UART 1 and UART 2)
Two Serial Peripheral Interfaces (SPI1 and SPI2)
Two General-Purpose 32-bit Counters/Timers
Watchdog Timer
Real-Time Clock/Sampling Timer (RTC)
LCD Controller (LCDC)
Pulse-Width Modulation (PWM) Module Universal Serial Bus (USB) Device
Multimedia Card and Secure Digital (MMC/SD) Host Controller Module
Memory Stick® Host Controller (MSHC) Direct Memory Access Controller (DMAC)
Synchronous Serial Interface and Inter-IC Sound (SSI/I2S) Module

General-Purpose I/O (GPIO) Ports Bootstrap Mode
Multimedia Accelerator (MMA)
Power Management Features
Operating Voltage Range: 1.7 V to 1.98 V core, 1.7 V to 3,3 V I/O


This is the breakdown of what is on the main board of the Jetbook. I find it interesting that it looks like there is a serial port for debug purposes. There is also the capability to run a monitor but it looks like the external components are not installed. This CPU also has the capability to run as a USB Host if the software stack where to be installed.

Thank you!

Wow. A 200 MHz Dragon Ball. That explains a lot about why some of the actions are sooo sloooow. It also explains how they can get a 3000 MAh battery to last for a week. You give, and you get.

Interestingly, I found that in some parts of the Libre firmware it is faster. When loading the books list, it takes a long time to load, but after it does, the menus and folders and nearly INSTANT (compare with a slight delay on each new page for the jetBook firmware). They must be caching the data.
