Timv moved page Space Salmon to SpaceSalmon: no space
This page needs to be filled. It needs to cover the SpaceSalmon Rocket Flight Computer developed by Tim Vrakas for SSI in 2018. Also we need to set up a "preceded by" box that links to SkyBass.
Space Salmon is the second generation (by some counting) rocket flight computer developed by SSI. It was preceded by the [[Skybass]] flight computer. In 2019, it gained a fishy younger brother, [[ThunderGuppy]].
SpaceSalmon built on the previous generation SkyBass flight computer. Unlike SkyBass, which was a rectangular PCB that mounted vertically I'm the vehicle, Space Salmon was built onto a circular disk-shaped PCB, which fit into the rocket horizontally. This disk stacking arrangement (known coloqially
as "Stack Boi") was intended to compactify the avionics and reduce mechanical weight.
The avionics stack used two 12-pin headers for electrical connection between boards. The A-Stack carried power, arming, and data bus lines, while the B-Stack carried charge activation lines downward to the bulkhead.
