The IceZero FPGA board is interesting. It is sold here.

Common features

  1. Fully Open-Source Hardware and Software Design.
  2. Lattice ICE40HX4K FPGA that supports Clifford Wolf’s Project IceStorm tool chain.
  3. Interfaces to Raspberry Pi 2×20 GPIO Header for both power and bus interfaces.
  4. PROM programmable directly from Rasp Pi, no JTAG programmer required.
  5. External SRAM, supporting soft CPU core designs ( code execution ).
  6. Extra large SPI PROM, supporting soft CPU core designs ( code storage ).
  7. Industry standard PMOD expansion headers
BML specifi features
  1. Mesa Bus Protocol 32 MHz SPI link between CPU and FPGA.
  2. 2-Layer PCB design. Orderable via OSH-Park or Gerbers for Downloading.
  3. FTDI 1×6 USB Serial Cable header for use with PC instead of Pi ( or as a soft CPU debug Trace Port ).
  4. Single Pi UART plumbed to FPGA for muxing to multiple external serial devices.
