Ecp5-stamp: common questions

What microcontroller does the Ecp5-stamp use?

The Ecp5-stamp is built around the LFE5U-12F-6BG256C, from the FPGA family.

How big is the Ecp5-stamp PCB?

The Ecp5-stamp measures 52.5 × 57.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Ecp5-stamp?

25 components, from 12 distinct parts. The full bill of materials is listed on this page.

Where can I download the Ecp5-stamp design files?

From the multigcs/riocore repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Ecp5-stamp design in my own project?

Yes, under the terms of its GPL-2.0 license, which multigcs chose for the repository.

Can I test firmware for the Ecp5-stamp 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.
