Nowadays, most development boards, sensors and breakouts feature Qwiic or Stemma QT plug-and-play connectors<\/a>, which allow you to set up projects very quickly by connecting multiple boards together. This handy Swirly grid allows you to easily mount various small microcontrollers and sensor boards.<\/strong><\/p>\n The grid consists of an \u2018aluminium PCB\u2019 \u2013 technically manufactured using a PCB process \u2013 but with a single-sided aluminium core; there is no copper here, just the painted aluminium substrate (black solder mask with silkscreen).<\/p>\n Aluminium is both electrically and thermally conductive, so take care if you use metal screws to secure items.<\/strong><\/p>\n Each square measures 15.24 mm \u00d7 15.24 mm (0.6 \u00d7 0.6 inches) and there are holes or slots every 5.08 mm (0.2 inches). With the various dots and dashes, you can fit practically anything onto the grid.<\/strong> Each hole has a diameter of 2.54 mm (0.1 inches), whilst the slots measure 2.75 x 7.5 mm (0.11 x 0.3 inches).<\/p>\n What\u2019s more, the aluminium is easy to work with, bend, cut and drill, should you require further customisation.<\/p>\n Technical details:<\/strong><\/p>\n Each pack comes with a universal 5\u00d75 support grid. Cables, sensors and microcontrollers are sold separately.<\/p>\n Using the script at the following link, you can access a generator that creates a custom KiCad grid <\/a>tailored to your requirements.<\/p>\n\n
