Building a CubeSat for less than $1000 -- Part 3 -- Avionics Schematic

Why are CubeSats / Cube Satellites so expensive? Entry level 1U satellites for basic science missions often cost at least $10 or $20K, and I figure that they shouldn't, given how cheap consumer electronics are. 2U / 3U and above satellites are even more expensive, not to mention the much much larger launch cost. Is the high cost justified by the unique operating environment and market demand for CubeSats?



Today I cover the schematic I created for the Avionics board of the Cubesat. The Avionics board essentially serves as the main computer for the Cubesat, including control of the Attitude Control System, and radio communications.
