STEPFPGA supports Verilog on cloud-based IDE and Lattice’s Diamond IDE

Jun 27, 2022 — by Giorgio Mendoza 451 views

The STEPFPGA MXO2Core is a compact platform based on the Lattice MX02-4000 FPGA. The low cost device is loaded with several I/O peripherals and it’s targeted towards FPGA beginners. The STEPFGA costs around $46 through a Kickstarter campaign that already surpassed its funding goal.

According to the developer company called EIM Technology, the STEPFPGA MXO2Core is an immersion gold four-layer PCB that it’s built around the Lattice MX02-4000. The learning board features a base clock frequency of 12MHz and maximum clock frequency up to 400MHz (boosted by internal PLL) and up to 36 GPIO pins.

The STEPFPGA MXO2Core provides two seven-segment displays, two RGB LEDS, eight red LEDs, four toggle switches, eight push-buttons and a USB type-c used for programming.


The company also offers a Web-based IDE to create projects based on Verilog. Additionally, the WebIDE contains basic project examples including full adders, decoders, segment displays, etc. EIM Technology recommends using Lattice’s Diamond IDE for more complex projects.

For an additional cost, the company will supply a book with hands-on experiments using motors, sensors and other electronics. The book doesn’t seem to be finished yet, but they released a preview of the table of contents.
