Nice prototyping FPGA platform, which inserts properly right into a breadboard, and will be simply embedded into any venture of yours

iCEBreaker-Bitsy

The FPGA board iCEBreaker Bitsy is an open-source FPGA growth board that may be a compact model (36mm x 18mm measurement) of the iCEBreaker FPGA growth board.

Out there in a Teensy kind issue, the iCEBreaker Bitsy is a good prototyping FPGA platform, which inserts properly right into a breadboard, and will be simply embedded into any venture of yours. 

The compatibility with the open-source FPGA design instruments like Yosys, nextpnr, IceStorm, Icarus Verilog, SymbiFlow, nMigen and others makes the board simple to work with. This implies the board is low price and has a pleasant set of options to permit for the design of fascinating tasks. On the identical time, the person can nonetheless select to make use of the proprietary vendor instruments.

Options & Specs

    • 128 Mbit (16 MB) quad SPI double knowledge price (QSPI-DDR) flash
    • 64Mbit (8MB) quad SPI (QSPI) pseudo SRAM (PSRAM)
    • Lattice iCE40UP5k FPGA5280 logic cells (4-LUT + Carry + FF)
    • 120 Kbit dual-port block RAM
    • 1 Mbit (128 KByte) single-port RAM
    • PLL, 2 x SPI, 2 x I2C onerous IPs
    • Two inner oscillators (10 kHz and 48 MHz) for easy designs
    • Eight DSP multiplier blocks for sign processing reminiscent of audio synthesis and software-defined radio
    • Low energy consumption splendid for battery-powered functions
    • Three 24 mA drive and three x onerous IP PWM (can drive RGB LEDs and small motors)

I/O choices embrace

    • A current-controlled RGB LED (present settable within the FPGA, additionally incorporates PWM onerous IP)
    • Two on-board indicator LEDs (one of many LEDs is shared with the PSRAM Chip Choose line)
    • One pushbutton
    • USB-C connector able to USB 1.x (Full Velocity) operation. Absolutely managed by the FPGA and obtainable to your FPGA designs (Formally supported by the LUNA venture)
    • 24 GPIOs across the fringe of the board, pinout appropriate with the favored Teensy boards. Distance between pins is appropriate with basic DIL IC sockets.

The FPGA board can host CPU soft-cores reminiscent of PicoRV32, PicoSoC, RISC-V and others which might be programmable by means of a pre-loaded DFU bootloader (simple to make use of with dfu-util)

The product will be obtained from 1BitSquared.com. As of now, it appears to be bought out however will turn into quickly obtainable after the conclusion of the CrowdSupply marketing campaign.
