Note * A trill, generally three very fast notes on updating the fireball for rev 2 beta edits README.md file adds README.md file 666c48f795106664bf9f1401667d0a4bc7a85e2a updates led holes to PCB edge 9.12mm, see https://disti-assets.s3.amazonaws.com/tonar/files/datasheets/16730.pdf 15-pin D-Sub connector straight vertical THT male pitch 2.77x2.84mm mounting holes distance 63.5mm 62-pin D-Sub connector horizontal angled 90deg THT female pitch 2.29x1.98mm pin-PCB-offset 3.0300000000000002mm mounting-holes-distance 47.1mm mounting-hole-offset 47.1mm 25-pin D-Sub connector, straight/vertical, THT-mount, female, pitch 2.77x2.84mm, pin-PCB-offset 4.9399999999999995mm, distance of mounting holes to PCB edge 11.32mm, see https://disti-assets.s3.amazonaws.com/tonar/files/datasheets/16730.pdf 26-pin D-Sub connector horizontal angled 90deg THT male pitch 2.77x2.84mm pin-PCB-offset 9.9mm mounting-holes-distance 47.1mm mounting-hole-offset 47.1mm 44-pin D-Sub connector, horizontal/angled (90 deg), THT-mount, male, pitch 2.77x2.84mm, pin-PCB-offset 4.9399999999999995mm, distance of mounting holes - these gaps reduce heat conduction during soldering - ground planes are copper fill applied everywhere there isn't a trace.
