Pyxida Rev. 5 was a major revision that included a new radio chip (CC1120) to replace the old xBee radio add on. Rev. 5 Also included a new breakout board expansion to allow more modules to be added to Pyxida without the need for an entire redesign and manufacturing of a new board. Breakout for this revision included a barometer breakout, programmer breakout, and pyro breakout. Unfortunately, this revision had several hardware issues (mostly related to manufacturing) that had to be resolved with a new revision.
Revision 6:
Pyxida Rev. 6 was a major revision completed during the 2018 Fall Semester. It includes a new breakout design using ribbon cables instead of pins to allow for more flexibility in placing breakouts in the avionics bay. It has a new radio chip (CC1200) and a radio amplifier (CC1190) to allow for longer range communication. It has a new backup battery system, and includes a LIPO charging feature, and allows for external batteries to be connected to Pyros if higher voltages are needed.
