Dogrudan sdr A: common questions

What microcontroller does the Dogrudan sdr A use?

The Dogrudan sdr A is built around the LFE5U-25F-7BG256I, from the FPGA family.

How big is the Dogrudan sdr A PCB?

The Dogrudan sdr A measures 235 × 225 mm, has 6 copper layers and is 1.6 mm thick.

How many components are on the Dogrudan sdr A?

279 components, from 79 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Dogrudan sdr A design files?

From the kocer/direct-sampling-sdr repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Dogrudan sdr A design in my own project?

The repository has no license, so all rights stay with kocer. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Dogrudan sdr A without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug FPGA firmware against it before you order a PCB.
