The mbed LPC1768 Development board puts the microcontroller onto a 40-pin DIP PCB to provide easy access to most of the microcontroller's I/Os and built-in peripherals. Plug the 40-pin DIP module into the optional mbed-Xpresso Baseboard or a breadboard and you have a powerful development and prototyping platform.
The mbed Microcontroller Module comes in a 40-pin, 0.1" pitch DIP form-factor so it's ideal for experimenting on breadboards, stripboards and PCBs. It supports USB, SPI, I2C CAN, Ethernet, and UART interfaces. Downloading programs is as simple as using a USB Flash Drive: Connect the mbed module via the miniUSB connection to your PC; the PC will recognize the module as a USB Flash drive; drag & drop your program binary to the FlashDrive and you're up and running!
The mbed Compiler is web-based, so it works on Mac, Windows, and Linux, and it allows you to write programs in C++. You'll also have access to the mbed libraries, which give you an API-driven approach to using the many functions of the microcontroller.
Also included is a C/C++ SDK for productive high-level programming of peripherals. Combined with the wealth of libraries and code examples being published by the mbed community, the platform provides a productive environment for getting things done.
This diagram shows the commonly used interfaces and their pinout locations. Note that all the numbered pins (p5-p30) can also be used as digital inputs or outputs. Some pinout options are not shown here; for a full details, see the NXP LPC1768 user manual or Datasheet.
