Please note that while there are some great introductory getting-started tutorials for this board, its best used by those with microcontroller experience. If you’ve played with AVR or PICs and are intrigued by the low cost and ultra fast 32-bit ARM Cortex M3 series, this is the dev board to get! If you’re just getting started with microcontrollers and electronics you should check out the Arduino which is very beginner-friendly.
In addition to publishing the schematics and layout files, MicroBuilder has written a full software library for the LPC1300 family. This allows you to quickly get started with all on-board peripherals, so you can focus on your own application functionality. The software library includes complete GCC-based startup code and details on setting up an ARM development environment using open source tools. Along with a standard Makefile, project files for the open-source CodeLite C/C++ IDE and the commercial GCC-based Crossworks for ARM are provided.
Within minutes, you’ll be using the USB interface for printf() debugging, reading from the analog inputs using analogRead(), tweaking pins without having to look up registers, etc. and best of all no ARM or JTAG programmer is required! The chip comes with a built in USB bootloader that appears as a very small disk drive. To reprogram, simply press the Bootload button and drag your new firmware file into the USB drive that appears. Then press Reset and your code is running. Is that cool or what?
Power the board via the 2.1mm DC jack (6-12V) or the mini-B USB connector (5V). There’s an onboard 3.3V regulator (LT1113)
Debugging LED on pin 2.10 and SWD connectors for programming and debugging
Open source toolchain (GPL) and software library (BSD)
USB 2.0 HID and Mass Storage support built right into the ROM
32K of flash, 8K of SRAM…running at 72 MHz
Built-into-ROM USB bootloader works with any computer and OS
Full Speed USB, TTL UART, SPI and I2C interfaces
Up to 42 General Purpose I/O (GPIO) pins with configurable pull-up/pull-down resistors
8 10-bit Analog-to-Digital Converter pins
Four general purpose counter/timers with a total of four capture inputs and 13 match outputs

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
