Know before you buy
The board is designed to work with the fully open-source Project IceStorm toolchain, which includes Yosys for synthesis and nextpnr for place-and-route. It also supports modern frameworks like Amaranth HDL and Icarus Verilog for simulation.
No, the iCEBreaker features an onboard bootloader that allows you to program the FPGA directly via the USB-C connection. You do not need any external hardware to get started.
Yes, the board features Pmod-compatible headers, allowing you to easily connect a wide variety of sensors, displays, and other expansion modules. The IO signals are length-matched to ensure signal integrity for your projects.
The PSRAM provides additional memory for projects that require more storage than the FPGA's internal block RAM can offer. It is particularly useful for applications involving data buffering or simple frame buffers.
Absolutely. The iCEBreaker is specifically tailored for students and educators, offering a well-documented, open-source platform that simplifies the learning curve for programmable logic.
The microSD slot allows you to interface with external storage, which is useful for loading configuration files, storing data logs, or implementing projects that require reading and writing files from a standard filesystem.
