About the Airsticks PCB

Airsticks is an open source STM32 PCB design by lizboyer, published on GitHub. It is a 2-layer board measuring 48.7 × 22.6 mm, with 16 components from 13 distinct parts.

Its main chip is the STM32G441KBT6, from the STM32 family. Other key parts include the PAM8302AAS and TC1262-33. By type, the board carries 5 connectors, 5 capacitors, 3 ICs and 1 resistor.

It belongs with the audio and sensors designs in this gallery.

From the project

Airsticks was a project by myself (Elizabeth Boyer), Christian Tchilikov, and Dearborn Plys. It uses accelerometers, a speaker, an STM32 MCU, and a board we created. The user puts the velcro cuffs onto a pair of drum sticks and - based off of the orientation and acceleration of the sticks- can play through drumset samples.

If a serial device is used to read directional output, Picocom or Putty can be used to print those outputs via UART, at a baud rate of 19200.

Airsticks: common questions

What microcontroller does the Airsticks use?

The Airsticks is built around the STM32G441KBT6, from the STM32 family.

How big is the Airsticks PCB?

The Airsticks measures 48.7 × 22.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Airsticks?

16 components, from 13 distinct parts. The full bill of materials is listed on this page.

Where can I download the Airsticks design files?

From the lizboyer/Airsticks repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Airsticks design in my own project?

The repository has no license, so all rights stay with lizboyer. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Airsticks without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
