Modular FPGA board
- Create few simple boards with different type of connectors
- Board will have powersupply and few leds -- changed to HDMI connector
- Order boards
- Study FPGA pinout and the way we can connect ECP5
- Have some pictures/animation of boards snapping together
- Assembly Board and test connections
- Start to work on module board that will have selected connectors
- Order board
- Have some pictures/animation of boards snapping together
- Assembly
- Board should slip into connector and blink some leds
- Starting to work on mainboard
- Add all ULX3S perifers to the board, and leave placeholders for new periferal
- User opinions, considering/fullfilling wishlists, beautification
- Blender animation
- Study other FPGA vendors
- Main board assembly
- Write verilog examples
- Test all onboard periferal
- Adding periferals to the board
- Ordering
- Start to work on some other vendor module board
- Do some blender animation with main board and different vendors
- Assembly main board
- Write some Verilog test examples
- Test onboard periferal

Questions
How big is the ULX4M GPDI PCB?
It measures 100 × 40.1 mm and has 4 copper layers, 1.6 mm thick.
What parts does the ULX4M GPDI use?
27 parts, built around the DF40C-100DP-0.4V(51) and DF40C-100DS-0.4V(51). The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the ULX4M GPDI KiCad files?
From the intergalaktik/ULX4M_documents repository on GitHub, at the commit this page was made from: the board is ULX4M_test/ULX4M_GPDI.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the ULX4M GPDI design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
