BeagleWire: fully open ICE40 FPGA BeagleBone cape

BeagleWire is a completely open source FPGA development board. Unlike most other FPGA dev boards, the BeagleWire’s hardware, software, and FPGA toolchain are completely open source.  The BeagleWire is a Beaglebone compatible cape leveraging the Lattice iCE40HX FPGA.

BeagleWire can be easily expanded by adding additional external modules for example, modules for high speed data acquisition, software defined radio, and advanced control applications. Using well-known connectors like Pmod and Grove makes it possible to connect various interesting external modules widely available in stores. Owing to this, prototyping new imaginative digital designs is easier.

E-Ink controller with ice40 FPGA

E-ink Display Driven DIY

E-ink displays are awesome. Humans spent centuries reading non-backlit devices, and frankly it’s a lot easier on the eyes. But have you looked into driving one of these critters yourself? It’s a nightmare. So chapeau! to [Julien] for his FPGA-based implementation that not only uses our favorite open-source FPGA toolchain, and serves as an open reference implementation for anyone else who’s interested.

Watch the E-Ink controller in action:

Design files and source code are available on GitHub:

IceZero FPGA Board for Raspberry Pi

Black Mesa Labs created this board that adds a Lattice FPGA to a Raspberry Pi:

ice_zero_with_pi_zero

IceZero FPGA Board for RaspPi

BML has been very much enchanted with the Lattice FPGA boards for Raspberry Pi, IcoBoard , BlackIce and IceHat. The IceZero board is a BML creation that attempts to combine the best features of all 3 boards into a single design.

IceZero features common with other designs

  • Fully Open-Source Hardware and Software Design.
  • Lattice ICE40HX4K FPGA that supports Clifford Wolf’s Project IceStorm tool chain.
  • Interfaces to Raspberry Pi 2×20 GPIO Header for both power and bus interfaces.
  • PROM programmable directly from Rasp Pi, no JTAG programmer required.
  • External SRAM, supporting soft CPU core designs ( code execution ).
  • Extra large SPI PROM, supporting soft CPU core designs ( code storage ).
  • Industry standard PMOD expansion headers

IceZero features that are BML specific

  • Mesa Bus Protocol 32 MHz SPI link between CPU and FPGA.
  • 2-Layer PCB design. Orderable via OSH-Park or Gerbers for Downloading.
  • FTDI 1×6 USB Serial Cable header for use with PC instead of Pi ( or as a soft CPU debug Trace Port ).
  • Single Pi UART plumbed to FPGA for muxing to multiple external serial devices.
