Ruggedized Arduino Solutions


Rugged Circuits Offers Premium Grade Arduino Compatible Microcontrollers, Shields, Accessories and Custom Design Services

Rugged Circuits products are designed and manufactured in the USA with built-in protective circuits and performance enhancing features that put them a LEVEL ABOVE standard Arduino devices.  We have invented a "RUGGEDIZED" market for those customers that need a more robust higher quality Arduino based solution.  Our products are specifically designed to offer greater performance, last longer, and operate in environments where standard equipment fails.  The circuitry has been modified to protect against ESD, reverse voltage, over/under voltage, over/under current scenarios which occur within the product environment and/or by user mistake. 

Our Maxim- "If it's not broke because it's Rugged-Dont Fix it."

With everything in life you get what you pay.  Our customers want products that don't fail and offer greater flexibility.  Whether you are monitoring sensors in arctic conditions and need a -40C controller that will endure, integrating with harsh 24V industrial controls and can't afford downtime, or producing a product and want to reduce failure rates and uphold your important reputation, Rugged Circuits has a solution.  We cater to industrial, corporate, educational markets as well as individuals.


We have THOUSANDS of satisfied customers since 2007 and rapidly gaining more!

We are excited to help YOU!  Take a deeper look into our website to learn more...






Something very "SMALL"  (With HUGE Capabilities) is coming soon!  Keep an eye on our website for updates.




Would you like to see a Ruggeduino SE/ET with Screw Terminals?  Send us your thoughts




Rugged Circuits introduces the NEW Rugged MEGA ST (Screw Terminal) and Rugged MEGA ET ST.  Ideal for industrial based applications.  Provides instant, secure, convenient connections integrated directly to PCB. 


ULTIMATE 24V Connectivity!

Stacking the Odds in Your Favor.  The Rugged Ultimate Stack leverages three of our robust hardware solutions to give you the Ultimate in performance and durability.  The Rugged MEGA provides ultimate I/O flexibility, 2560 processing power, and a multitude of safeguards which extend protection to micro and the shields.  The QuadRAM lends increased processing power and maximum headroom for demanding applications and larger sized sketches.  The 24V Industrial I/O Shield tops everything off with 24V connectivity.  The Rugged Ultimate Stack offers PLC like control from an Arduino based solution!  



24V !?!?  Yes REALLY!

New Photos and information added to the 24V Industrial Shield Page.  Check out all the great features this shield provides for integrating with 24V Signals.




MEGA Aussie Shield Pro is here.  35mm standard DIN Rail Mounting for Industrial applications.  Provides instant clean access to ALL Mega pins.




The Rugged MEGA and Rugged MEGA ET have been updated to "Industrial Ready" status.  The power supplies have been carefully modified and tested to achieve even greater performance and reliability.  The new sections are more efficient, quieter, more robust, and operate more consistently across the entire operating voltage range.  Output current has doubled from 150mA to 300mA at 3.5V input and up to 500mA with 24V input.  ET versions have carefully selected components to obtain a -40C rating making  it ideal for arctic and automotive applications where temperatures plummet to -40C.  The Rugged MEGA and MEGA ET are truly unique in that they are the only Arduino based platforms that can operate up to 30V and down to -40C.  Now that's COOL!

Why Rugged Circuits?

The videos show the "little things" that go into the the thought process and design of our products to make "big differences" in performance and reliability.   Inspired by our "10 Ways to Destroy an Arduino" these videos provide an in depth look at just how easy it is to damage a standard Arduino and how we have thoughtfully created a superior solution.  The Ruggeduino SE/ET and Rugged MEGA PROTECT you from ALL 10 methods of destruction.  The protective features of Ruggeduino and Rugged MEGA make them the ideal Arduino UNO and MEGA derivative board.   Rugged products will outlast and outperform regular Arduino boards and save you time and money.  Our products are not just intended to safeguard against mistakes, they are designed to endure grueling environments.
