OpenSourceMID.org is founded by a group of engineers enthusiastic in modern technologies and open source software development and sponsored by Timll Technic Inc. in China. It is an open community to provide support and discussions for K7 MID or any other open source MID projects through this website.

OpenSourceMID.org, itself, is an Open Source project. This means, first, that we offer not only a product but a process, and second, that we depend upon the contributions of developers and endusers to make that process happen. The easiest way for you to help us out is to join the overall OpenSourceMID.org project by join OpenSourceMID Community.


K7 MID is a low-cost, high-performance handheld Mobile Internet Device featuring Texas Instruments' OMAP3530 ARM Cortex-A8 core processor with, wireless connectivity, touch screen control, GPS navigation systems and integrated power management with battery backup. It can support for both Android and WinCE operating systems and would be a complete solution that addresses all of the user's multimedia and communication needs on a single platform.

How to use the OTG port as the UART debug port

1. Download the USB driver for Windows "Littleton USB Driver for Windows.rar" and extract it.
2. Connect K7 to your computer's USB port. Windows will detect the device and launch the Found New Hardware wizard. Vista/7 users need to cancel the automatic driver update.
3. Select "Locate and install driver software."
4. Select "Browse my computer for driver software."
5. Click "Browse..." and locate the folder where you extracted the driver. As long as you specified the exact location of the installation package, you may leave "Include subfolders" checked or unchecked—it doesn't matter.
6. Click "Next." Vista/7 may prompt you to confirm the privilege elevation required for driver installation. Confirm it. The driver will be installed.
7. Download the Android SDK for Windows "android-sdk_r07-windows.zip" and extract it.
8. Run the cmd in Windows.
9. Enter the commands below:

cd D:\android-sdk-windows\tools
adb.exe shell

Now the OTG port is working as the UART debug port. You can install applications from computer. Enter the command below:

  adb.exe install D:\AdobeReaderv10.0.0.apk
