Boards using the X201632MKB4SI
5 boardsBoards in 3 GitHub repositories, designed in KiCad, that use the X201632MKB4SI by YXC (-40℃~+85℃ 32MHz 80Ω 8pF Crystal Oscillator ±10ppm ±20ppm SMD2016-4P Crystals ROHS). See how each wires it, with its parts, size, README and files; the X201632MKB4SI’s symbol, footprint and pinout are on its own page.
