Lattice FeatherWing – An iCE40-powered add-on FPGA board for Adafruit Feather
Oak Development Technologies has recently announced Lattice FeatherWing – An iCE40-based development board designed to be controlled by Adafruit Feather. Previously we wrote about the IcyBlue Feather V2, a standalone development built around a Lattice Semi iCE5LP4K FPGA. But this FeatherWing board is designed to add functionality to your existing Adafruit Feather board. The Lattice FeatherWing expands your Adafruit Feather with a Lattice iCE5LP4K FPGA. It connects and gets programmed over SPI so you can use all the FPGA’s GPIO pins through the header blocks. There’s also a built-in RGB LED directly connected to the FPGA’s open-drain pins, for visual feedback. Previously, we have written about many Lattice Semi FPGA-based development boards, such as the tinyVision.ai Pico-Ice board, Silicon Witchery S1, and ULX3S Education Board. Feel free to check those out if you want a standalone FPGA board. FPGA – Lattice Semi iCE40 Family ICE5LP4K-SG48ITR Logic Cells – Approximately 3520 logic cells Memory – 80 Kbits […]
