This is the repository for the SuperBIT Data Recovery System (a.k.a. the data drop capsule).
The DRS comprises:
- Raspberry Pi equipped with: 1 x 512GB and 4 x 128GB (RAID1) SD data storage
- ATSAMD21G18 microcontroller as used on the Adafruit Feather M0 Adalogger and the Arduino Zero
- u-blox MAX-M8Q GNSS receiver
- Iridium 9603N Short Burst Data modem
- Maxtena M1600HCT-P-SMA antenna, shared via a Skyworks AS179-92LF RF switch
- two servo-actuated Scott Archery release aids: one for the tether and one for the parachute
- Rocketman 4' parachute
- Low extraction force power connector
- 3D-printed cover
- PU foam enclosure
- PVC launch tube
See LEARN.md for more details.
PCB.md contains instructions on how to populate and test the PCB.
PI.md contains instructions on how to configure the Raspberry Pi.
ASSEMBLY.md contains instructions on how to prepare the DRS for flight.
GoGoGo.md contains instructions on how to release and track the DRS.
The schematic, PCB layout and Bill Of Materials can be found in Data_Recovery_System_V1.pdf
The BOM is also available in Excel .xlsx format
The Eagle directory contains the schematic and pcb design files.
The Arduino directory contains the Arduino code for the SAMD microcontroller.
The Drawings directory contains the drawings for the trigger linkage.
The OpenSCAD directory contains the OpenSCAD and STL files for the 3D-printed cover, release crown/mount, and heatsink.
The Python software tools which need to be installed on the Raspberry Pi can be found the DRS_Python_Tools repo.
See SERVO.md for details on how to modify the HiTec servo for high altitude operation.
See SHARK.md for details on how to modify the Scott Archery Shark release aid.
