What is it?

The STEP-MXO2 Dev Board is a small, breadboard friendly 40-pin DIP form factor board built around Lattice MachXO2 FPGA. The board includes a USB-JTAG programming circuit, clock source, two digital displays, three RGB LEDs, four push buttons, eight LEDs, four switches, one hard-core SPI, one I2C, and basic I/O devices. These components make it a formidable, compact, platform for digital logic circuits and Micro32 embedded soft-core processor designs using Lattice Diamond development software. There are 36 Digital FPGA I/O signals (30 GPIOs, four dual-functional pins default to SPI interface, and two dual-functional pins default to I2C interface) that are routed to 100-mil-spaced through-hole pins so that you can integrate your programmable design directly into a solderless breadboard circuit. At just 0.72 inch by 2.05 inch, it can be loaded in a standard socket and used in embedded systems.

Why did you make it?

It is difficulty to learn FPGA, not only because the content and material is complicated to understand, but also access the hardware is a challenged. I want to make a educational-purpose for entering level to learn FPGA.

What makes it special?

• Easy to use, small form factor and low cost – STEP-MXO2 Dev Board is a breadboard friendly 40-pin DIP form factor board build around Lattice’s award-winning MachXO2 FPGA.
• Rich features and expandable options – On board JTAG programming circuit, 36 Digital FPGA I/O signals, one IP-core SPI interface and one I2C interface that are routed to 100-mil-spaced through-hole pins so that you can integrate your programmable design directly into a solderless breadboard circuit. It can also be loaded in a standard socket and used in embedded systems.
• Learning materials suitable for FPGA learners – A variety of learning materials, including QuickStart guide, user manual, schematic document and demos are provided. Introductory FPGA training courses are available to those who are new to the FPGA world.
