ADAU1701 Universal Audio DSP Board
drag ‘n drop DSP’ing—and no SMDs to solder
It seems that to even dip your feet in the ocean of DSP (digital signal processing) you need lots of SMD soldering skills and a ton of math. Seems. Let’s end the anxiety: here is a Universal Audio DSP board for the DIYer. Based on the Analog Devices ADAU1701 DSP, this board has only through-hole components—except for the DSP itself, which Elektor PCB Service reflow-solder in place especially 4 U.

CAM/CAD data for the PCB referred to in this article is available as a Gerber file. Elektor GREEN and GOLD members can exclusively download these files for free as part of their membership. Gerber files allow a PCB to be produced on an appropriate device available locally, or through an online PCB manufacturing service.
Elektor recommends its business partner Eurocircuits as the company of choice for its own prototypes and volume production in selected cases.

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.
