If you like my work, please consider buying me a coffee! This is a complete amplifier based on a PAM8403 chip or similar. I used common electronic pieces that you can get very cheap in China (3.50€ total per unit for me including printing) and designed around it for a wide variety of components. The PAM8403 isn't especially loud but I have many uses for a small amplifier like that, such as kitchen/bathroom radios. You can completely alter the design via the Fusion360 archive file to suit your components or remove the texts. If you print one of my things, please let me know!
