Altoids Amp – Bill of Materials

Altoids amp BoM

Kits are available from IEEE — contact the current IEEE representative, listed on the resources page.
The BoM includes everything needed to make the amplifier PCB. To complete the project and use the amp, you will also need:
- an empty Altoids tin (or some other small enclosure)
- two 9-V batteries
- an audio cable with 1/8" TRS connectors
- wired headphones with a TRS connector
If sourcing/scrounging your own parts, the usual comments apply.
Here is a csv file of the BOM that can be uploaded directly to Digi-Key for speedier ordering. Be sure to edit the csv file if you intend to delete any items or change quantities.
