An introduction
Hey fellas it's Technical here with a cool beans board!!! I wanted to experiment with FPGAs and RAM at the same time, so I thought, why not just combine the two onto one board! What a great idea right!!! Hahahahahahhahaha! But yeah thats how this board came to be... At the time of writing (10/5/25), the board only has a few key parts needed for it to function.. HOWEVER, I am planning to put more cool stuff onto it, as I have like 150 IO pins left lol... Feel free to DM technical_. on the Hack Club slack if you have any ideas for what to put!!!
Features (As of 10/5/25)
- Lattice ECP5 FPGA
- 44k LUTS
- 1944 KiB of Embedded Memory
- 351 KiB of RAM
- DDR3 RAM
- 2GB
- DDR3??
- 100 Mhz clock (probably)
- Snazzy Name

Questions
How big is the Minty PCB?
It measures 64 × 45.5 mm and has 6 copper layers, 1.6 mm thick.
What parts does the Minty use?
119 parts, built around the LFE5U-45F-7BG256I, FT231XQ-R, W25Q128JVSIQ and TPS74801DRC. 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 Minty KiCad files?
From the techn1-cal/Minty-FPGA repository on GitHub, at the commit this page was made from: the board is Minty_PCB_Files/Minty.kicad_pcb and its schematic Minty_PCB_Files/Minty.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Minty design in my own project?
Its repository states no licence, so its author keeps all rights: ask techn1-cal before reusing the design.
