This board is no longer in production. The replacement for this board is the OM13058 (LPCXpresso11U68)
The mbed NXP® LPC11U24 Microcontroller in particular is designed for prototyping low cost USB devices, battery powered applications and 32-bit Arm® Cortex™-M0 based designs. It is packaged as a small DIP form-factor for prototyping with through-hole PCBs, stripboard and breadboard, and includes a built-in USB FLASH programmer.
The mbed Microcontrollers provide experienced embedded developers a powerful and productive platform for building proof-of-concepts. For developers new to 32-bit microcontrollers, mbed provides an accessible prototyping solution to get projects built with the backing of libraries, resources and support shared in the mbed community.
