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!

Compact Desktop Media Control with ANAVI Macro Pad 2

Do you remember the ANAVI Macro Pad 2, our tiny mechanical keyboard with just two keys? Built around the Microchip ATtiny85 microcontroller, it comes with QMK version 0.13.19 and is often used as a cool copy-paste keypad. However, its open-source firmware can be reprogrammed for various uses. Recently, Henrik shared a Crowd Supply “field report” about his impressive setup, using the ANAVI Macro Pad 2 to control audio streams with his favorite songs. Although the ANAVI Macro Pad 2 was successfully funded on Crowd Supply three years ago, in June 2021, we continue to update the documentation and share news with our backers. It’s fantastic to keep improving the product based on community feedback.

Henrik created a custom QMK keymap for the ANAVI Macro Pad 2 based on his needs: the left button is for “play/pause,” and the right button is for “next song.” He even configured the LEDs to light up when the buttons control media playback. Why hire a DJ when you can be the DJ with your homemade setup using the ANAVI Macro Pad 2?

After modifying the firmware, Henrik made a hardware customization. For fun, he changed the keycap on the right button to one featuring a sleeping unicorn. This new keycap, being heavier than the default translucent one, adds weight to the otherwise lightweight ANAVI Macro Pad 2. The keyboard comes with Gateron red mechanical switches, which are Cherry MX compatible, allowing for easy keycap changes. Henrik also shared his plans for future modifications, including a second custom keycap.

Nowadays, the ANAVI Macro Pad 2 is available for purchase from our distributors worldwide. If you need any help, feel free to get in touch. The user manual is available on GitHub. For more details about Henrik’s setup, check out his Crowd Supply field report.
