Introduction:

iCESugar-pro is a FPGA board base on Lattice LFE5U-25F-6BG256C, which is fully supported by the open source toolchain (yosys & nextpnr), the board is designed in DDR2 SODIMM form with 106 usable IOs, with on-board 32MB SDRAM, it can run RISC-V Linux. the on board debugger iCELink (base on ARM Mbed DAPLink) support drag-and-drop program, you can just drag the FPGA bitstream into the virtual disk to program, and with a additional USB CDC serial port direct connect to FPGA, so you can only use one TYPE-C cable to develop and test.
