The '''Balloons Gen 1 Avionics Platform''' is the first core avionics suite developed by HABEES. Named ''Oscar'', this avionics suite flew on a failed technology demonstration in SSI-39, followed by a successful demonstration in SSI-40. As the first core avionics suite, it set the expectations for features to be included in subsequent revisions.

=== RTC ===
A DS1307 RTC IC is utilized for the real-time clock. The Teensy 3.2 internal RTC is avoided due to past difficulties/problems. The DS1307 is powered by 5V (no 3.3V variety exists). A 32.768kHz 12.5pF time-keeping crystal X1 is used for the RTC, and a keystone 12mm coin cell holder provides backup power for the RTC. A 100 nF decoupling cap is provided.

The payload was recovered floating atop algae in an irrigation canal. All flight electronics remained in nominal state at time of recovery. The Micro SD card contained thorough data from throughout the entire flight.
