mbeDshield
(13.July.2015) updated to 0.6.0
(01.May.2014) started sales of 0.5.0! http://www.switch-science.com/catalog/1717/
(13.March.2014) updated to 0.5.0
This is a pin conversion PCB from mbed 1768/11U24 to arduino UNO.
- So if you have both mbed and arduino shields, I guess you would be happy with such a conversion board :)

BIG changes from previous version
- Ethernet RJ45 connector is removed.
- http://mbed.org/components/Seeed-Ethernet-Shield-V20/ is the biggest hint to use Ethernet!
MostALL of components can be bought at Akizuki http://akizukidenshi.com/- But sorry, they do not send parts to abroad
- Pinout is changed!

This design has bug(s)
- no bug found for 0.6.0 so far
Fixed bugs here
I2C functional pin differs between 1768 and 11U24(0.5.0 issue)- This has been fixed from 0.6.0
MiniUSB cable cannot be connected on mbed if you solder high-height electrolytic capacitor on C3(0.4.0 issue)- This has been fixed from 0.5.0: http://akizukidenshi.com/catalog/g/gP-05002/ is the solution to make this 100% AKIZUKI parts!
the 6-pin ISP port is not inprimented (0.4.0 issue)- This has been fixed from 0.5.0
I am doing some porting to use existing arduino shields but it may faster if you do it by yourself...
you can use arduino PinName "A0-A5,D0-D13" plus backside SPI and I2C ports for easier porting.
To do this you have to edit PinName enum in
- "mbed/TARGET_LPC1768/PinNames.h" or
- "mbed/TARGET_LPC11U24/PinNames.h" as per your target mbed.
here is the actual list: This list includes define switch to switch pin assignment
