Backplane updates

Sensor

Selected ICs
Started research into other components
Selected breakout boards Finalized ICs

Power

got power requirements from everyone
Moving from 1 switcher to 2 LDOs to 1 switcher to each LDO

Backplane

gave james power
allocating
only guaranteeing digital signals, no guarantees on noise w/ analog signals
going w/ SwitchBlox instead of an IC
- 5 ports
- magnetics
- has an STM32 for managed mode (w/ SW support)

Radio

Selected breakout boards
Most components selected

Autopilot

Picking out CPU candidates, main candidates:
- STM32
- VoCore2
- STM32WL radio MCU
  - bad software support (Makefile project is buggy w/ CubeMX)

Backplane timeline -have CDR week after irec CDR with all mod perlimiatry layout @Ben Hyman (RIT Student) @Yevgeniy Gorbachev (RIT Student)

IREC PDR

Whole Team

Action items

THINK OF NAME

IREC Avionics bay

Other mece for ave bay

Yev updated ave bay to fit in in coupler tube

PDR this weekend

Timeline

IREC COTs

PDR

Timeline

Finalize components

Bridge wires

Backplane

Autopilot @Ben Hyman (RIT Student)

Radio @Dante Sivo (RIT Student)

Design breakout boards for XBee and GPS and EEPROM (XBee will be a bit longer lead time so need to get in)

Buy components for breakouts

Breakout need to by stencil

Everyone use the same flash

discuss LEDSSs remove WS2813B-8 @Ben Hyman (RIT Student)

Backplane @Billy Siegener (RIT Student) (Deactivated)

Each module add an LEDs on a GPIO line

Talk about LEDs

Buy SwitchBlox ethernet switch (2x please)

Link microchip application note regarding magnetics

Team to look over data sheets of SwitchBlox then buy components @Ben Hyman (RIT Student) @Yevgeniy Gorbachev (RIT Student)

Sensor @Mary Dertinger (RIT Student) @Louis Fleisher (RIT Student)

Design breakout boards

Buy breakout board

Select remaining components

Power @James May (RIT Student)

Finalize power calculations

Everyone use the same flash
