Introduction

Heads up! This tutorial was written for ARM microcontrollers with SWD or JTAG pins. You will need a dedicated programmer (i.e. J-Link EDU Mini or J-Link EDU Base) to connect to the port. If you are using an AVR microcontroller with an Arduino bootloader using ICSP pins, you'll need to head on over to the Installing an Arduino Bootloader tutorial.

SparkFun has been a fan of Arduino for a long time. We've programmed ATMega328s (and 168s, and 8s before that), written tutorials, and hacked all sorts of fun projects. But now the market is maturing and we are looking at a lot more ARM chips. One advantage of the newer chips is that they generally do not need a USB-to-serial adapter; instead they have USB built in (at least the ones we are using do). You still need to add a bootloader to use them with Arduino, and since ARM programmers are also a little more complicated than AVR programmers you'll want to invest in a stand alone programmer instead of trying to use the Uno you have laying around.

What exactly IS a PCB? This tutorial will breakdown what makes up a PCB and some of the common terms used in the PCB world.

Installing an Arduino Bootloader

This tutorial will teach you what a bootloader is and why you would need to install or reinstall it. We will also go over the process of burning a bootloader by flashing a hex file to an Arduino microcontroller.
