About the Gecko5education PCB
Gecko5education is an open source FPGA PCB design by logisim-evolution, published on GitHub under the MIT license. It is a 6-layer board measuring 60.6 × 100 mm, with 308 components from 57 distinct parts.
Its main chip is the LFE5U-85F-6BG381x, from the FPGA family. Other key parts include the 93CxxC, FT2232HQ, TFP410PAP, 74HC154BQ,118 and W25Q128JVS. By type, the board carries 124 diodes, 96 resistors, 31 capacitors, 18 ICs, 17 transistors and 8 switches.
From the project
Openhardware educational platform based on the ideas of the ulx3s and Gecko4Education
The Gecko5Modular is a new take on an open hardware educational platform. The ideas of the Gecko5Modular are based on the open hardware ULX3S board, the Gecko4Education line of boards, and the recently developed Leguan development board.
This is a small (60.6x100 mm) standalone FPGA board for education, research and general purpose. It's open source and open hardware. It continues my line of educational boards used in the past for teaching and research projects.

Gecko5education: common questions
What microcontroller does the Gecko5education use?
The Gecko5education is built around the LFE5U-85F-6BG381x, from the FPGA family.
How big is the Gecko5education PCB?
The Gecko5education measures 60.6 × 100 mm, has 6 copper layers and is 1.6 mm thick.
How many components are on the Gecko5education?
308 components, from 57 distinct parts. The full bill of materials is listed on this page.
Where can I download the Gecko5education design files?
From the logisim-evolution/GECKO5Education repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Gecko5education design in my own project?
Yes, under the terms of its MIT license, which logisim-evolution chose for the repository.
