ReDIP-64: common questions
What microcontroller does the ReDIP-64 use?
The ReDIP-64 is built around the LFE5UM5G-25F-8MG285C, from the FPGA family.
How big is the ReDIP-64 PCB?
The ReDIP-64 measures 25.4 × 50.8 mm, has 6 copper layers and is 1.57112 mm thick.
How many components are on the ReDIP-64?
137 components, from 54 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 ReDIP-64 design files?
From the daglem/reDIP-64 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 ReDIP-64 design in my own project?
The repository has no license, so all rights stay with daglem. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the ReDIP-64 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.
