Custom iCESugar-nano FPGA Development Board Open Source RISC-V iCE40LP1k Standard PMOD Connector Manufacturer

Introduction

iCESugar-nano is an open source FPGA development board based on Lattice iCE40LP1k-CM36 designed and made by Muse Lab. It's fully supported by the open source toolchain (yosys & nextpnr & icestorm). All the IOs are led out with 3 standard PMOD connectors.

The on-board debugger iCELink based on ARM Mbed DAPLink supports drag-and-drop programming. You can just drag the FPGA bitstream into the virtual disk to program. Besides, the iCELink provides a adjustable clock to FPGA and a additional USB CDC serial port direct connecting to FPGA. Just with one TYPE-C cable, you can start to develop and test the board.

Features

iCE40LP1k main chip, 1280 LUT/8KB SRAM/PLL On-board iCELink debugger, supporting drag-and-drop programming and USB CDC serial port Lead out 14 usable IOs with one 2*6 Pin PMOD connector and two 1*6 Pins PMOD connectors Totally use open source tool chain to develop On-board 2MB SPI-Flash W25Q16
