Project links

Here are some useful links related to the components, tools, and technologies used in the projects.

Availability and exact component variants may change over time, so always verify datasheets and full part numbers before use.

Note: similarly named components may not be compatible. For example, DAC IC AK4490EQ is not the same as AK4490REQ and is not pin-compatible.
