About the article



As far as microcontrollers and some of their owners go the analog world out there first needs digitizing before it can be understood. This miniature but powerful ADC breakout board (BoB) does the job.

The BOM (Bill of Materials) is the technically exhaustive listing of parts and other hardware items used to produce the working and tested prototype of any Elektor Labs project. The BOM file contains deeper information than the Component List published for the same project in Elektor Magazine. If required the BOM gets updated directly by our lab engineers. As a reader, you can download the list here.
