Av Bay Dimensions | CubeSat specification:
- Width-Max: 10cm
- Depth-Max: 10cm
- Height-Max: max sub-board length, 10cm ?
Mother Board Dimensions:
- Width: 10cm
- Height: 10cm?
- 2x2cm cut outs from corners
- D'sub 37 position two row connectors for motherboard daisy chaining
- Dual edge connectors perpendicular to motherboard for daughterboard
- See connector spec docs for pinout
12V, 5V, 3V3 Wire gauge, Amp max
Current Draw:
- 2A, 3V3 (radio)
- WHAT DO THE OTHER BOARDS NEED???
Chassis Ground???
- Depends on what material the chassis is made of
The can bus protocal runs through the board top to bottom. And is daisy chained at top and bottom
Maximum signaling rate of 1 megabit per second (bps). 120Ω terminating resistance
Maybe if we have radio bandwidth
RSB: UART (~5Mbs)?
What are the connector pins assigned to? Gotta figure out what power requirement look like before asignment can be made.
- DBC RSB Radio Board (Ana)
- Camera Board??
- DBC Flight Control Board FCB (El-Mougey)
- DBC Camera Interface Board CIB ()
- SAC Data Aquisition DAQ (Rhoda)
- PC Battery Management Board BMS ()
- PC Power Management Board PMB
- Contains bateries and BMS and PMB.
- Raw Battery Power Never Touches the MotherBoard
- BMS will connect to mother board for DAQ
- PMB connects to mother board to supply power
- Contains standard Ave bay PCBs
- Any number of these may be used based on number of PCBs
- DAQ board lives here (has sensors connected)
- Actuator board
- Wall mount connectors for all sensor connectors (Patch/GPS intena included)
- Pick connectors daughter board and mother board daisy chain
- Pick connectors for wall mount connectors sensors (Rhoda + Mohammad)
- Find total current draw
- Determine how terminating resistors work with daisy chain
- CAD the SatCube Structure
