The ATmega128RFA1 is a portmanteau of sorts – two separate components combined to form one device; half microcontroller, half RF transciever. ATmega128RFA1 is an IEEE 802.15.4 compliant single-chip, combining the industry- leading AVR...

The next rev of the RedBot Mainboard has received a few improvements to the silkscreen and has an added button connected to pin 12, go check it out. This page is for reference only. The RedBot Mainboard is a robotic development platform...

Here is a powerful, low-cost, reliable servo for all your mechatronic needs. This servo is able to take in 6 volts and deliver 83.47 oz-in. of maximum torque at 0.16 sec/60° This is a tough little servo with a standard 3 pin power and...

Side-looking Infrared Emitters and IR Detectors. These simple devices operate at 940nm and work well for generic IR systems including remote control and touch-less object sensing. Using a simple ADC on any microcontroller will allow...

This is a breakout board for the L3G4200D low-power three-axis angular rate sensor. The L3G4200D is a MEMS motion sensor and has a full scale of ±250/±500/±2000 dps and is capable of measuring rates with a user-selectable bandwidth....

Running out of memory space in your Arduino project? The microSD Shield equips your Arduino with mass-storage capability, so you can use it for data-logging or other related projects. A microSD quickstart guide is available!...

These 33mm (1.3") spring loaded pogo pins are great for programming and applications where you don't always want headers soldered onto your boards. We use them for our programming jigs in production. The pins fit snugly into most...

You’ve always wanted to output analog voltages from a microcontroller, the MCP4725 is the DAC that will let you do it! The MCP4725 is an I 2 C controlled Digital-to-Analog converter (DAC). A DAC allows you to send analog signal, such as...

This is a breakout for the SOIC version of the 74HC595 shift register IC. Clock in data and latch it to free up IO pins on your micro. All pins from the IC are broken out to standard 0.1" spaced headers. The Serial in and out pins are on...

The ScrewShield extends all pins of the Arduino out to 3.5mm pitch screw terminals. It also has a lot of the utility provided by Arduino Protoshield , including: a large prototyping space of both connected and unconnected 0.1" spaced...

Here at SparkFun, we refuse to leave ‘good enough’ alone. That’s why we’re adding to our line-up of Arduino-compatible microcontrollers once more! The Pro Micro is similar to the Pro Mini except with an ATmega32U4 on board. The USB...

This is a Arduino-compatible autopilot board designed by Chris Anderson and Jordi Muñoz of DIY Drones using the ATMega328. This revision uses the ATmega2560 in place of the ATmega1280. ArduPilot Mega is a fully programmable autopilot...
