Ecp5-dev board: common questions
What microcontroller does the Ecp5-dev board use?
The Ecp5-dev board is built around the LFE5U-12F-6BG256C, from the FPGA family.
How big is the Ecp5-dev board?
The Ecp5-dev board measures 68 × 43 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Ecp5-dev board?
107 components, from 33 distinct parts. The full bill of materials is listed on this page.
Where can I download the Ecp5-dev board design files?
From the medhyal/ecp5-dev-board repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Ecp5-dev board design in my own project?
The repository has no license, so all rights stay with medhyal. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Ecp5-dev board 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.
