The mbed NXP LPC1768 is an easy-to-use MCU development board designed for rapid prototyping. At its heart is a powerful 32-bit ARM Cortex-M3 processor running at 96 MHz with 512 KB flash and 32 KB RAM, which makes it far more capable than popular 8-bit prototyping alternatives. A comprehensive firmware library and plenty of sample code help you get your program up and running quickly, and a free online IDE and C++ compiler means that no software installation is required. Downloading programs is as simple as using a USB flash drive (no external programmer is necessary).

The mbed NXP LPC11U24 is an easy-to-use MCU development board designed for rapid prototyping. At its heart is a low-power 32-bit ARM Cortex-M0 processor running at 48 MHz with 32 KB flash and 8 KB RAM, which makes it more capable than popular, similarly-priced 8-bit prototyping alternatives. A comprehensive firmware library and plenty of sample code help you get your program up and running quickly, and a free online IDE and C++ compiler means that no software installation is required. Downloading programs is as simple as using a USB flash drive (no external programmer is necessary).

The Pololu m3pi robot consists of a 3pi robot base with a fully assembled m3pi expansion board as its second level. This expansion board enables the use of a powerful 32-bit mbed development board as the robot’s high-level controller, which offers significantly more processing power and free I/O lines than the 3pi’s built-in 8-bit AVR microcontroller. There are also sockets for Wixel and XBee wireless serial modules as well as prototyping space for additional sensors and electronics.
