What is it?

FPGA prototyping board by Lattice Semiconductor FPGA(LCMXO2-1200HC-4TG100C). 1280LUT is enough for most of quick and interesting application.

Why did you make it?

Lattice MachXO2 has Embedded Function Block (EFB), which enables easy I2C device prototyping using FPGA. I did want to try this function and tried in relevant hackaday project. We can find Lattice's breakout board in market but sometimes they are too complex or expensive, or requires extra device for tackling for the first time on FPGA. Therefore I made a simple board.

What makes it special?

Five tactile sw, 7 LEDs, two digit 7-seg LEDs and piezo sounder on board.
On-board programmer. No need extra JTAG. Just connect USB cable is enough to enjoy this board.
Full Lattice Diamond compatible.
By the sake of EFB, we can make our original I2C device (and SPI) as we wish.
By the sake of free programming environment (Lattice Diamond), no need of extra expense.
Lattice have provided lots of reference design not limited to I2C and we can try quickly.

Nice low-cost started board with all you need to get going.

I am quite happy with this little FPGA starter board. The built-in JTAG worked perfectly with the free Lattice Diamond IDE (the board was auto-detected). The buttons, LEDs, 2 digit seven segment display, piezo sounder and 12Mhz clock give you something to play with right away. The possibility for easy I2C and SPI is nice too. The MachXO2 has enough LUT space and embedded RAM to implement some interesting designs (here is a version of Ben Eater's breadboard CPU that I implemented in VHDL to help get you started https://github.com/XarkLabs/BenEaterVHDL). Nice job!

I am also so happy to read your wonderful exploring FPGA board and enjoying CPU implementation!!! Your achievement is indeed beyond my expectation and thank you so much for sharing your VHDL code. I would like to try your CPU, thank you!!!
