Forking Open Source Hardware Right: The ANAVI Macro Pad 10 and the Rise of MATOSIC MACROPAD

ANAVI Macro Pad 10 is our programmable keypad with 9 mechanical switches and a rotary encoder built around XIAO module with Raspberry Pi RP2040 microcontroller. ANAVI Macro Pad 10 was crowdfunded through Crowd Supply on November 7, 2022 and it is now available at Crowd Supply, Mouser and Lectronz. It illustrates how open hardware can act as a reusable foundation rather than a fixed product. Released under the permissive license Creative Commons Attribution-ShareAlike 4.0 International (CC BY-SA 4.0), ANAVI Macro Pad 10 allows others to study, modify, and fork the design while keeping attribution and share-alike requirements intact. That structure makes it easy for developers to adapt the device for different workflows without starting from scratch.

A recent fork is the MATOSIC MACROPAD, created by Hrvoje Matosic in Mexico City. It reworks the original design of ANAVI Macro Pad 10 into a compact macropad aimed at developers using AI-assisted coding tools. What makes this case interesting is not just the fork itself, but how naturally it extends the original design’s intent. The ANAVI Macro Pad 10 was never locked to a single use case, which makes it flexible enough to evolve into tools for new computing trends like AI-driven development workflows. This kind of reuse is exactly what open hardware licensing is meant to enable.

The project has also been certified by the Open Source Hardware Association with UID MX000040 on June 05, 2026, marking it as an officially recognized open hardware derivative from Mexico.

ANAVI Macro Pad 10 was also certified by the Open Source Hardware Association with UID BG000093 on January 11, 2023. Hrvoje shared his fork on GitHub. In this context, each derivative project strengthens the original ecosystem. The MATOSIC version does not replace the ANAVI design, it builds on it, showing how small, well-documented devices can become platforms for experimentation and productization.

Overall, the ANAVI Macro Pad 10 demonstrates how open source hardware grows through iteration. Its value is not only in what it is, but in what others can turn it into, from hobby builds to even certified commercial products!

Step-by-Step Video Guide: Assembling Your ANAVI Dev Mic

The ANAVI Dev Mic is a small, open-source microphone kit designed for hobbyists and developers. It’s easy to assemble on your own, even with minimal tools. While you can complete the assembly using just your hands, a screwdriver will make the process quicker.

Components

When you open the ANAVI Dev Mic kit, you’ll find the following parts:

  • Black PCB with gold plating and white markings
  • Acrylic top cover
  • Acrylic bottom cover
  • Four 10 mm screws (M2.5)
  • Eight M2.5 nuts

NOTE: The kit does not include a USB-C cable. You can use one you already have or buy one separately.

Step 1: Remove Protective Layer

The acrylic covers are laser-cut and come with a protective film on both sides. Carefully peel off this film to reveal the clear acrylic.

Step 2: Attach the Top Cover

Take the PCB and the top acrylic cover, which has a circular cutout for the microphone. Align the cover with the corresponding circle on the PCB. Insert a screw into each of the four mounting holes and secure them with the nuts provided.

Step 3: Install the Bottom Cover

Next, place the bottom acrylic cover over the side of the PCB where the XIAO RP2040 module is located. Secure the cover by tightening it with the remaining four nuts.

Step 4: Connect and Use

With these simple steps completed, your microphone is ready to go. Just plug ANAVI Dev Mic into your computer using a USB-C cable, and you’re good to go!

ANAVI Handle was Certified as Open Source Hardware with UID BG000134

The Open Source Hardware Association (OSHWA) officially certified our new gadget ANAVI Handle in April. ANAVI Handle is a small USB-C adapter with XIAO RP2040 that allows you to use Wii Nunchuk-compatible controllers as USB HID peripherals on your personal computer. You can configure ANAVI Handle to adapt the controller as a joystick, keyboard or a mouse.

OSHWA, a prominent U.S.-based non-profit, manages the Certified Projects Directory and annually hosts the prestigious Open Hardware Summit. Their certification program ensures that a project’s interpretation of “open source hardware” aligns with the community’s standards, promoting transparency and accessibility.

Each certified hardware version is identified by a unique identification number (UID) that includes a country code and a numerical sequence. On April 19th, ANAVI Handle version 1.0 was certified with the UID BG000134. This UID, displayed through the OSHW Certification Mark, simplifies navigation and information access for interested parties. The “BG” prefix indicates that the ANAVI Handle is from Plovdiv, Bulgaria, a city renowned as Bulgaria’s second-largest and Europe’s oldest continuously inhabited city, with over 6000 years of history.

Our projects, including the ANAVI Handle, are distinguished by our unwavering commitment to complete openness. Every aspect of our design and functionality is made accessible to all, reflecting the true spirit of the open-source community. From the KiCad-designed printed circuit board to the highly-configurable firmware powered by CircuitPython, we exclusively use free and open-source software.

We launched ANAVI Handle on the market through a successful crowdfunding campaign at Crowd Supply. Place your order now to be among the first to experience the ultimate open-source USB adapter for your Nunchuk controller!
