Holes are pre-drilled for two High Light boards mounted end-to-end, but will also mount three Quantum Boards with extra drilling.
Will not accommodate driver mounts.
Designed for remote drivers.
Heatsinks include 5mm mounting holes at each corner and in the middle of the heatsink (6x total) for ratchet hangars or aluminium tie bar connectors etc, plus an 8mm cable hole in the middle of board.
These are basically a heavier version of a Slate 2 triple heatsink.
