Questions

How big is the Dc sdr PCB?

It measures 88.9 × 38.3 mm and has 4 copper layers, 1.6 mm thick.

What parts does the Dc sdr use?

113 parts, built around the RP2040, BGA2817, W25Q16JVUXIQ and ECS-2520SMV-120-FP-TR. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Dc sdr KiCad files?

From the AlexandreRouma/dc_sdr repository on GitHub, at the commit this page was made from: the board is dc_sdr.kicad_pcb and its schematic dc_sdr.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Dc sdr design in my own project?

Its repository states no licence, so its author keeps all rights: ask AlexandreRouma before reusing the design.
