DSP Active Crossover/DDS/Reflow Oven PCB patterns (PDF download) [01106191-6]
PDF with the PCB designs for the six boards used in the DSP Active Crossover project (all double-sided).
These same boards (except for the one coded 01106191) were also used in the February 2020 Low-distortion DDS Signal Generator project.
Similarly, the subset of boards coded 01106193, 01106195 and 01106196 were used in the DIY Reflow Oven Controller project from the April 2020 issue.
The boards coded 01106193 & 01106196 were used again in the Intelligent Hybrid Power Supply (February & March 2022).
Both layers of all boards are in a single PDF, one PCB per page.
