ColorLight I5 Module
The ColorLight I5 module is designed and sold to drive LED displays. As such they make a lot of them and get the FPGA cheaper than they are commonly available.
Features
- ECP5 LFE5U-25F FPGA
- 24000 LUTs
- 56 sysMEM block RAMs of 16kb each

Button and LED Board
The Extension Board has got a number of I/O's neatly arranged together in groups of 8, each group with it's own 3.3V power and GND. To be able to add input buttons and output LED's, I created a small I/O board for this purpose.
In order not to put a load on the I/O pin, the LEDs are driven by a MOSFET.
When a I/O port is running as an input (need a pull down) the LED will light up when the button is pressed.
