Ecp5-pcie: common questions
What microcontroller does the Ecp5-pcie use?
The Ecp5-pcie is built around the ECP5_EVN_PCIe, from the FPGA family.
How big is the Ecp5-pcie PCB?
The Ecp5-pcie measures 115 × 85.8 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Ecp5-pcie?
49 components, from 16 distinct parts. The full bill of materials is listed on this page.
Where can I download the Ecp5-pcie design files?
From the ylm/ecp5-pcie repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Ecp5-pcie design in my own project?
The repository has no license, so all rights stay with ylm. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Ecp5-pcie 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.
