S4 Payload

Small Satellites for Secondary Students, or “S4” is an Arduino Based electronic payload from Sonoma State University, AeroPac, and the Endeavour Institute.  A custom printed circuit board (PCB) is available from Sonoma State University; AIAA OC Rocketry has a small supply of the boards from Sonoma State for SPARC.  This custom PCB has positions for an Arduino Uno to plug in and communicate with a GPS module and several sensors.  A WiFly module provides a real time telemetry downlink using standard WiFi frequencies and protocols.  Firmware for the payload and software for a ground station is also available along with documentation.  More information can be found at the links below:
