Ether: common questions
What microcontroller does the Ether use?
The Ether is built around the ECP5U_85_CABGA756, from the FPGA family.
How big is the Ether PCB?
The Ether measures 152 × 70 mm, has 6 copper layers and is 1.6 mm thick.
How many components are on the Ether?
197 components, from 26 distinct parts. The full bill of materials is listed on this page.
Where can I download the Ether design files?
From the korken89/ether repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Ether design in my own project?
The repository has no license, so all rights stay with korken89. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Ether 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.
