iCEBreaker-bitsy FPGA Open Source Development Board

Soon a new open source iCE40 FPGA development board in a Teensy Form factor will be introduced through the Crowd Supply website and features a board supported by the following FPGA design tools: Yosys, nextpnr, IceStorm, Icestudio, nMigen and Litex. Unfortunately no information on prices or worldwide availability has been published yet, but as always we will keep you informed as soon as information becomes available.

“ICEBreaker-Bitsy FPGA adds the powerful flexibility of an FPGA to your next project in a convenient Teensy form factor. It works out of the box with the latest open source FPGA development tools and can be easily integrated into a variety of projects. “

Specifications of the iCEBreaker-bitsy FPGA Development Board

  • iCE40UP5k FPGA
    • 5280 logic cells (4-LUT + Carry + FF)
    • 128 KBit (16 KB) 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 the onboard RGB LED)
  • QSPI DDR-capable Flash 128 MBit (16 MB)
    • Allows hardware designs that access the flash; Choosing double data rate quad SPI flash allows designs to be executed at very high speeds.
  • QSPI pseudo-SRAM 64MBit (8 MB)
    • Provides additional RAM for more memory-intensive designs.
  • Lots of I / O capable pins
    • On board RGB-LED for status display
    • Two discrete on-board LEDs
    • A USB-C interface that is fully controlled by the FPGA (allows the implementation of any low- and full-speed USB devices)
    • A push button on board
    • 24 PINs on the edge pads, compatible with breadboards, 24pin IC sockets and SMD soldering
  • Built-in DFU bootloader for easy programming
    • Natively supported by the dfu-util tool
    • Can be switched to bootloader mode from the user bitstream either with a push of a button or a DFU stub.

The iCEBreaker-Bitsy FPGA development board is designed to be compatible with the widely used Teensy microcontroller boards. This gives you access to a library of carrier boards and extensions that can be used for prototyping, gateware and firmware development. Thanks to the Teensy to Feather adapter board, you can also access the constantly growing Adafruit Feather ecosystem. “
