April 2025 Open Source Hardware Certification Roundup

The Open Source Hardware Association (OSHWA) runs a free program that allows creators to certify that their hardware complies with the community definition of open source hardware. Whenever you see the certification logo, you know that the certified hardware meets this standard.

Currently the Certification database lists over 3,011 individual certifications! In April we added 19 new certifications, from to and everything in between; we were happy to have new and recurring names show up! Here are three certifications we think you should check out today.

Rebelia Hand UID IT000021

We were so excited to see this open source prosthetic hand for humans and robots come through the certification database! The Rebelia Hand is a 3D-printed hand that can be made for minimal cost with a small difference between the human and robot versions, where the human prosthetic includes a wrist rotation flange and a socket for the upper limb equipped with two EMG sensors. It’s been incredible to have so many open healthcare certifications come in as we explore this area more and this one is an incredible addition to open source hardware!

Line Follower UID IR000001

The Line Follower Printed Circuit Board is a really excellent first certification coming out of Iran! This lovely little PCB is able to detect lines based on shadows and lights, and cooperate with Arduino microcontrollers. The Line Follower was developed for line-following robots in educational and agricultural robotics, though we won’t be surprised when it gets utilized in other ways. With infrared sensors, a dynamic threshold algorithm and modular PCB architecture, it can achieve a 95% tracking accuracy.

Mathpad UID UK000074

Okay math nerds! Here’s the certification for you! The Mathpad is a specialized keypad designed to make typing out your mathematical equations and symbols so, so much easier. Perfect for students, researchers, engineers, data fans and big nerds who like to do math for fun, it’ll make your mathematical notations a breeze and cut down on those annoying struggles to get all those symbols in your equations.
