  • Siddharth Muralikrishnan Ahmed Osman Anthony Lazar Anthony Luo Shawn Yang

  • coming along, schem long in a week and layout in another week seems doable

  • LTE Breakout - Electrical - WARG (atlassian.net)

    • Canceled, now part of RPi Interface Rev C - Electrical - WARG (atlassian.net)

  • green tasks need to be done → need a lot of new components for this board, anyone is welcome to take them, but I actually need these done

  • Most components added to Library

• 12V -> 5V @ 4A Buck Converter + ELRS Board - Electrical - WARG (atlassian.net)

  • Kenny NaEngineer

  • Daniel Puratich PM

  • Layout in progress ~ 1 week, will be ready for midterm board order

• 24V->5V @ 5 A Buck Converter Board - Electrical - WARG (atlassian.net)

  • Schematic is under review by Kevin

  • Robert TangEngineer

  • Kevin Li PM

  • Placement almost completed

  • Will be ready for midterm board order

• Unified Video System - Electrical - WARG (atlassian.net)

  • Tom Chiu Individual Contributor

  • Layout revamped

    • New stackup will be

      • L1 - SIG/PWR

      • L2 - 2 signal traces, but otherwise, all GND

      • L3 - Uninterrupted GND

      • L4- SIG/PWR

    • Rerouted all signal traces on top and bottom layers with many via transitions. 2 signal traces remain on L2

    • I tried to ensure that the 2 traces on L2 did not lose gnd reference signal traces do not lose reference.

    • Removed 2 decoupling caps on the buck to save space.

    • Sourced a smaller linear regulator for the 12V-5V step down to save space as the current one is overkill based on the required power draw from it.

    • Please review whenever possible!

  • Worked with Jerry to understand the existing VTX system. Helped a bit with installation and creating the harness for PWM signal from pixhawk to lumenier switch board.

• 12S ESC - Electrical - WARG (atlassian.net)

  • Ethan Abraham Individual Contributor

  • Schematic nearly complete. Need to change MCU pinout to abide by AM32 hardware groups

  • Looking for a somewhat experienced EE to handle/help me with layout

• ELRS Redundant Diversity RX - Electrical - WARG (atlassian.net)

  • Nolan Haines Individual Contributor

  • Schematic completed, starting placement

  • Doesn’t need help but might later with routing

• Sensor Cluster - Electrical - WARG (atlassian.net)

  • Michael Botros

  • Schematic done, implementing some schematic feedback from Daniel

    • So far no one else has left any schematic comments

  • Going to start layout likely this week

• Pegasus wiring documentation

  • Ahmed Osman Jerry Tian

  • https://github.com/UWARG/hardware/tree/master/Harness schematic is here

...

• Needs Assessment (comparing to the manual test procedure we have rn):

  • 1. characterize our custom buck converter’s performance.

  • 2. understand our designs more, help ee members learn

    • Load transient test is helpful on identifying issues if downstream board is brownout during flight test

    • Knowing efficiency of the bucks

  • 3. efs running out of work to do

• Jerry’s was stuck on communicating

Action Items

...

• is too busy to work on this rn, will be on hold until he is more free

Action Items

Jerry Tian will try to fix hot air gun, if not successful, he will write email to hakko for help
