The PCB layout for Oscar can be seen on the right.
The PCB layout for Oscar can be seen on the right. Oscar was notable for its novel shape -- a 3/4 hexagon, designed to fit perfectly in a Gen 1 HABHIVE container and allow some space for routing wiring and positioning a RB/battery pack vertically.
Oscar also notably has battery protection and boost circuits locally, on the bottom right hand side. This is the first and last instance that a Core Avionics suite contains on-board battery protection/boosting. Subsequent power circuits are relocated to an external BMS. Oscar is also notable for very low part density -- this is in part due to its large size, which, although more large than necessary, is defined as such for mechanical purposes. Oscar also features surface mount Molex Microfit connectors, which are replaced in subsequent lines of avionics platforms in exchange for smaller footprint through-hole varieties. Oscar is the first and only avionics suite to only use the perimeter pins of the Teensy 3.2 -- subsequent avionics all use the additional underbelly pins.
Oscar has three mounting holes, designed for #8 bolts, for mechanical integration into HABHIVE.
