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]].
But I wanted a permalink!

 +
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.
