This FPGA breakout board was designed as part of an effort to document how to get started with FPGA programming, from the hardware design files to loading a bitstream. In order to try and make this accessible as a project, one of the design goals for this board was for it to be feasible to assemble by hand, using only a soldering iron. To that end, all of the critical components are leaded packages, and there are no passives smaller than 0805. For some components (USB type-C connector J4, 12MHz oscillator X1 and RGB LEDs D1 and U4), a hot air gun may be advantageous, but it is possible to get away without one.
All of the design files for this board, as well as firmware and gateware, can be found in the associated Github repo here:
