	The main controller for our payload will be a Teensy 3.2 from PJRC. This micro controller not only is compatible with Arduino code and the Arduino IDE, but contains a host of additional features including an ARM processor, 2 I<~~math~~>^{2}</~~math~~>C channels, and capabilities to connect to a CAN bus.

	The payload and the booster sections will each contain two altimeters for redundancy (four altimeters total). Each altimeter will be wired up to the ejection charges mounted on the respective avionics bays as well as to a cable cutter for our reefing system. Since both the payload and booster section will be reefed, there will be redundant cable cutters for both parachutes as well (four cable cutters total). The reefing system will be discussed in detail in ~~'''2.7~~ Recovery~~'''~~.		The payload and the booster sections will each contain two altimeters for redundancy (four altimeters total).
