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.
