Ssla: common questions
What microcontroller does the Ssla use?
The Ssla is built around the ECP5U_25_CABGA256, from the FPGA family.
How big is the Ssla PCB?
The Ssla measures 81 × 49 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Ssla?
214 components, from 29 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 Ssla design files?
From the korken89/ssla 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 Ssla 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 Ssla 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.
