Based on LATTICE iCE40UP5K chip FPGA development board, using open source software development board hardware geda design,
Can use the Diamond LATTICE official software, iCEcube2 development, also can use open source software yosys, nextpnr, icestorm development,

Open source software development has been in the development platform of virtual machine installed, in the virtual machine to programming development board is slower than the real machine, please wait patiently,

This is the first time proofing four of the five block model, individual screen printing device parameter error and adjust the trace of manual welding, mind can wait a moment later the version, thank you,
