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
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter

Will there be a topic on your forum for this product? It sounds very interesting as a step up from Arduino, but I’m sure we could all use some help getting started with it, and the Adafruit community seems like it would be very helpful.
What’s a SWD connector? I haven’t run into that one before…
SWD stands for Serial Wire Debug, and is the native way that all ARM Cortex chips handle debugging (versus JTAG on the older ARM7 chips). It only requires 2 pins, and allows for more HW breakpoints in code, but it’s only relevant if you have a HW debugger that can handle SWD (such as the Segger J-Link for ARM). Some larger Cortex M3 chips work with both SWD and JTAG, such as the LPC1768, but most of the smaller chips are SWD only. If you’re not doing step-through debugging, though, you don’t really need to worry about it and can get by with printf and the built in USB bootloader to program the chips and do basic debugging.
