It's blue! It's skinny! It's the Arduino Pro! SparkFun's minimal design approach to Arduino. This is a 3.3V Arduino running the 8MHz bootloader. Because the system voltage for this board is lower than other Arduino development boards, it may not be compatible with many Arduino shields which were designed to run at 5V. The Arduino Pro 3.3V still works great with our prototyping shield so you can create your own 3.3V shields. The lower system voltage also has its advantages, like ease of use with many common 3.3V sensors.
It's blue! It's thin! It's the Arduino Pro Mini! SparkFun's minimal design approach to Arduino. This is a 3.3V Arduino running the 8MHz bootloader. Arduino Pro Mini does not come with connectors populated so that you can solder in any connector or wire with any orientation you need. We recommend first time Arduino users start with the Uno R3. It's a great board that will get you up and running quickly. The Arduino Pro series is meant for users that understand the limitations of system voltage (3.3V), lack of connectors, and USB off board.
These headers are made to work with the Arduino Uno R3, Leonardo and new Arduino boards going forward. They are the perfect height for clearing the USB-B connector and great for stacking multiple shields. This kit includes 4 headers (2 8-pin, 1 10-pin and 1 6-pin), enough to connect a shield to an Arduino board. These are the same headers we use in our tutorials and with our own shields.
This is your tried and true white solderless breadboard. It has 2 power buses, 10 columns, and 30 rows - a total of 400 tie in points. All pins are spaced by a standard 0.1". The two sets of five columns are separated by about 0.3", perfect for straddling a DIP package over. The board accepts wire sizes in the range of 29-20AWG.
This is probably the smallest Arduino controller speically designed for controlling the servo. It features a 12 standard servo control capbility with Xbee socket which can be used to control helicopter or UAV via the Xbee link. The feather weight (7.5g) make it an ideal controller for those application that has limited payload. The build in regulator is allow the input voltage vary from 3.5-8V which fits the most power supply without any modification.
This DFRoobot relay shield V2.1 is a completely new desgin which is capable of controlling 4 relays. The max switching power could be DC 90W or AC 360VA. It could be directly controlled by Arduino/DFRduino through digital IOs with external 9v supply. With buildin xbee type socket, it can be wirelessly controlled via Xbee/bluetooth/WPM. Make it an ideal solution for home automation and robotics purpose.
