This is a single pole, 10 position rotary switch able to select up to 10 different states in a durable package. Unlike our other rotary switch, this model is much more robust and capable of handling larger currents and voltages. With a...

This is the Circuit Scribe Conductive Ink Pen, a simple looking ball-point pen that allows you to draw circuits instead of soldering or wiring them to a breadboard. This is the same pen found in the Circuit Scribe Lite Kit just without...

This is the Parallel Gripper Kit A, a simple and durable robotics kit that is great for “getting a grip” on pretty much any robotics project! Designed for use with any standard size Hitec servo with a 24T spline, the gripper kit is easy...

This is the MyoWare Proto Shield, a simple proto-board for your MyoWare Muscle Sensor. With this shield you will be able to use the area provided to solder on whatever custom circuitry you can come up with. This shield provides 8 x 15...

The MyoWare Power Shield is designed to take two standard CR2032 coin cell batteries to power the MyoWare Muscle Sensor. We have made this board in a way that the coin cell batteries are connected in parallel for extended capacity at a...

This is a piezoresistive force sensor from Tekscan. The harder you press, the lower the sensor’s resistance. Pressing hard, the resistance changes from infinite to ~50k. The sensor itself is thin and flexible, but the resistance does not...

LiPo batteries are a great way to power your projects. They’re small, lightweight, and pack a pretty good punch for their size. Unfortunately, even the best batteries eventually run low on power and when they do it’s often unexpected...

This is the SparkFun ESP8266 Thing Dev Board – a development board that has been solely designed around the ESP8266, with an integrated FTDI USB-to-Serial chip. The ESP8266 is a cost-effective, and very capable WiFi-enabled...

Blynk is an easy to use app builder that allows users to add a variety of buttons, sliders, graphical displays and even RGB controllers to their phone. The SparkFun Blynk Board is specially designed to work with the ‘widgets’ within the...

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...
