    XEV10-7.5-B 2pcs
    XEV10-5-B 2pcs
  •  Board Molex connector + crimp List Daniel Lin
  •  Off-board Molex Connectors list Brian Nguyen (Deactivated)
    -MX150Ls going through enclosures
  •  Find more docs on the motors James L
    -Inductance specifications
  •  Find mating connector for motor sensor wires James L
    -check motor datasheet
    -Shielded cable to use to connect to the motor controller
  •  Josh Rong Figure out AUX switch implementation on the last car, and make it better on this car.
  •  
  •  Talk to interiors to sort out front electronics enclosures and accessibility
  •  Talk to interiors about solar box enclosure and LOCATION Aashmika Mali

Path To ASC Qualifying (Everything required for regs)

  •  Telemetry Pei Liang Guo
    -CAN wireless dongles?
    -LoRa?
    -Point to point wireless?
    FSGP vs ASC conditions
  •  Lights Heatsinking
    -Heat pipes
    -mounting to lights boards (screws)
  •  Former user (Deleted) Lights Mounting
  •  Board Molex connector + crimp List Daniel Lin
  •  Off-board Molex Connectors list
    -MX150Ls going through enclosures
  •  Battery Module Connector Board Ricky H
  •  Horn mounting Darby Smyth
    -Waiting for adrian
  •  GPS Module - RPI Daniel Lin
    -uBlox modules?
  •  Setup Controller board pick and place - VBA script? Darby Smyth
    -Length, width, height of components
    -Pick Angle relative to Altium Libraries
  •  Find more docs on the motors James L
    -Inductance specifications
  •  Figure out Heating of U2 (CAN Transceiver) on charger interface board Aashmika Mali
    -compare schematics with motor controller interface
    - see Charger Interface Testing . Issue was dead MCP2515
  •  Wiring diagram for the Elcon - J1772 Adapter Darby Smyth
    -Which wire are we using for this connection?
    -match the diagram for the mating ends
  •  Enclosure for MOV Charge Monitoring (read ASC regs)
  •  Mounts for driver ventilation fans
    -Noctua NF-F12 iPPC 3000
    -Talk to Adrian
  •  Find all nomuras to use (x11)
    -maybe remove nomuras from ms12
    -Do we need more?

Path to Success at ASC (everything that the team would really like to have)

  •  Battery Module Connector Board Ricky H
  •  GPS Module - RPI Daniel Lin
    -uBlox modules?
  •  Setup Controller board pick and place - VBA script? Darby Smyth
    -Length, width, height of components
    -Pick Angle relative to Altium Libraries
  •  Revisit power budget Josh Rong
    -Better documentation!
    -We need to figure out if we are as close to the power limit as we thought we were
    Aashmika Mali and Micah Black to make a list of the power draw in the car
    -We added a Sanity Check page to the google doc, and are evaluating alternate solutions for the horn.
  •  Powering the horn from another source? Liam Hawkins
  •  Lower priority - fan control board (PWM generator)
  •  Find all nomuras to use (x11)
    -maybe remove nomuras from ms12
  •  Find mating connector for motor sensor wires James L
    -check motor datasheet
    -Shielded cable to use to connect to the motor controller
  •  UV cutoff board Liam Hawkins - needed for horn and driver fans - talk to micah for more details
    -use load switch to activate mosfet for current path from lead acid to component
    -load switch will also get voltage level from battery (AND with rear power 12V signal to activate)
    -maybe charger feature @ 50mA
    -will use 5AH 12V Lead acid pack (probably from amazon) - also test with 1AH one to see if that would work with 5 min horn on time in regs
    -regs for supplemental battery enclosures - what is needed?
  •  Josh Rong Figure out AUX switch implementation on the last car, and make it better on this car.
  •  Talk to interiors to sort out front electronics enclosures and accessibility
  •  Talk to interiors about solar box enclosure and LOCATION Aashmika Mali
  •  Find bimetal switch on digikey to control DC-DC fan. Should be Normally Open (NO) and be able to provide at least 0.3A.
  •  Provide a suggestion for wireless tyre pressure monitoring system (TPMS)

Team Efficiency Improvements

  •  Reformat the altium libraries to make sure the following are taken care of
    -obsolete components are deleted
    -”Manufacturer Part Number 1” is a parameter updated for all components
    -No component uses cut tape or Digi-real
    -the polarity of components matching pads/pins matching silkscreen is correct
    -all parts that (like the standoffs) have correctly implemented keepout layers
    -for more info talk to Micah BlackJosh Rong or Aashmika Mali (or any other lead)
  •  Go through this page we use before every board sendout and format it better plus update content to be more extensive Checklist for Gerbers
  •  Provide a suggestion for wireless tyre pressure monitoring system (TPMS)
