Low Power FPGA dev board can be pre-ordered for $69.95

Feb 6, 2023 — by Giorgio Mendoza 780 views

The IcyBlue Feather by Oak Dev Tech is a tiny development board based on the Lattice ICE5LP4K low-power FPGA. This development board provides flexible peripherals such as up to 22x GPIOs, LiPo battery support and it can be programmed using the open-source Project IceStorm.

As mentioned earlier, the board is powered by the ICE5LP4K FPGA which offers up to 3520 LUTs/440 LABs. Additionally, the board includes up to 2MB SPI Flash memory.

This development board comes in a feather form-factor, however the product page indicates that the following images are of the prototype version. The final PCB will be blue with solder mask. 

In addition to the 22x GPIOs, the IcyBlue Feather features 1x RGB LED, 2x programmable LEDs, 2x hardened SPI IP cores and 2x hardened I2C IP cores. The board can also be used in portable applications since it includes support for 1S LiPo batteries.

The device includes an FTDI FT232HQ USB to FIFO bridge to easily program the board’s SPI Flash memory with bitstream, hex or bin files. Furthermore, the FT232HQ is compatible with Lattice’s Diamond programmer (proprietary) or with IceStorm (open-source).

Further information

The standard price of the IcyBlue Feather seems to be $84.95, but it can be pre-ordered for $69.00. The product page can be found on the OakDevTech online store. The first 100 pieces are estimated to ship around May.

    And now for the questions not answered here, or on the home Web page:
    What voltage does it run on?
    What voltage is the I/O ?
    Is it 5V tolerant, for use with Arduino boards?

    Mentioning SPI, I2C, and LiPo batteries means it PROBABLY runs at 3.3V or lower but you won’t know for sure – until you hook up an LCD module that uses 5V logic, and promptly fry your new investment.
