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!
