IceZero with Lattice ICE40HX, 4 Mbit external SRAM, 3.05 x 6.5 cm (TE0876-02-A)

With the exception of another flash manufacturer, this module is identical to its previous version TE0876-02.

The IceZero is a low cost general purpose Lattice FPGA platform for the Raspberry Pi. It includes 4 Mbit of external SRAM and 4 2x6 Pmod interfaces for 32 3.3V LVCMOS IO's to external expansion devices. The board is powered and configured over the standard 2x20 Raspberry Pi header. The ICE40HX4K FPGA is fully supported by Clifford Wolfs "icoTC" Project IceStorm tool chain.

Example designs (both Verilog and Python) for the SUMP2 Logic Analyzer and general purpose GPIO (inputs, outputs, PWM servo control, etc.) are available from the Black Mesa Labs website. Mesa Bus Protocol virtual PCI 32bit communication between FPGA and Pi is supported over the Pi's 32 MHz SPI serial interface. Black Mesa Labs strives to provide multiple free open-source example designs for the IceZero platform for expanding RaspberryPi hardware interface capabilities -bitstream complete- no FPGA design experience required.
