iCEBreaker FPGA – Open source iCE40 FPGA development board




The first open source iCE40 FPGA development board designed for teachers and students. It’s comming soon on CrowdSupply.

Are you ready to venture into the brave new world of digital logic design? The iCEBreaker FPGA board is specifically designed for you. It’s designed to work out of the box with the newest open source FPGA development tools and next generation open CPU architectures.

The iCEBreaker FPGA board is designed to accept the widely popular PMOD connectors. This gives you access to a massive library of modules that can be used no matter your project. You can find a large collection of PMOD modules in the Digilent online store. For several use cases, we have also developed our own PMOD modules and we keep adding more as they are developed.

The iCEBreaker is a great teaching and learning platform. We already have a list of educators developing their workshops and classes using the iCEBreaker as their target platform.

The iCEBreaker FPGA prototypes are already supported by the following FPGA design tools:

Feature list:

  • iCE40UP5k FPGA
    • 5280 Logic Cells (4-LUT + Carry + FF)
    • 128 KBit Dual-Port Block RAM
    • 1 MBit (128 KB) Single-Port RAM
    • PLL, Two SPI and two I2C hard IPs
    • Two internal oscillators (10 kHz and 48 MHz) (for simple designs)
    • 8 DSPs (16×16 multiply + 32-bit accumulate) (for digital signal processing)
    • 3x 24 mA drive and 3x hard IP PWM (for driving RGB LEDs or other high current devices)
  • QSPI-DDR-capable flash 128 MBit (16 MB)
    • Enables hardware designs that access the flash; by choosing a Quad SPI Double Data Rate flash lets designs to run at very high speeds.
  • Lots of I/O capable pins:
    • Three PINs for RGB LED (pin header)
    • Two on-board LEDs
    • One UART, 1 Rx & 1 Tx Pin accessible via virtual serial port of the board USB connector
    • One on board push button
    • 16 PINs on a not-dedicated dual PMOD
    • Eight PINs on single PMOD / snap-off section
READ  Microcontrollers with USB interface are common, but…
