• Peggy 2 Lighting Board Rev 3

  • https://uwarg-docs.atlassian.net/wiki/x/BYAzow

  • validate CAN circuit with CAN DSHOT Controller before assembling this

  • let’s assemble the bottom side this weekend?

  • other side need to wait for LCSC order

  • Daniel will participate in session for sure but would be nice if someone here to PM

• Single Servo Module

  • https://uwarg-docs.atlassian.net/wiki/x/HgA4ow

  • for fixed wing, assemble before midterms

• 6S Servo Module

  • 6S Servo Module Test Plan

  • for fixed wing, assemble before midterms

  • Saw small power trace in schematic, tested and it seems fine. Might be worth another rev?

  • Can bring up with what we have

    • conclusion

      • bring up one, test with EFS

      • fix layout, order with midterm board order

• 12S Servo Module - Electrical - WARG (atlassian.net)

  • Jerry Tian

  • On hold to focus on comp critical Peggy 2 tasks.

...

• Jerry Tian For Peggy 2

• Tracking antenna discussed above

• Integrated Monitoring and Command Station Requirements (IMACS) - SysInt - WARG (atlassian.net)

  • Nathan Green Do you wanna talk about this a bit?

• IR filters don’t really work

  • Auto looking for new solution

  • Detect heat?

  • Come to comp sync

• Video System installed on Drone

  • Camera wire length reworked, pending review from Nathan

Fixed Wing Updates - Fixed Wing 2025 - SysInt - WARG (atlassian.net)

• Reminder: Our newest program

• First arch sync of the term last week 2024-09-25 Fixed Wing Arch Sync - Meetings - WARG (atlassian.net)

• Timeline: Finished end of term

• Mech is cooking, see minutes

• The below boards should be included

  • 6S servo module

    • would be worth rolling out an updated rev if we can to fix a minor issuemaking new rev to be ordered with midterm board order

  • Single Servo Driver

    • should be good, needs assembly.

  • 6S power module

    • highest risk

      • lowest necessity (RIP lol - Andrew)

  • CAN Integration 2025

Bootcamp Updates

• Continue to pop off and ask questions in your bootcamp thread

General Tasks

In order of priority. These are the active design projects.

• RPi Interface Rev C - Electrical - WARG (atlassian.net)

  • Daniel Puratich Project Manager, Principle Hardware Engineer

  • 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

Potential new project: Standard connectors fixed wing

...

Potential new project: Test Automation

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

Action Items

This section is here for completeness. If a new task is assigned in a meeting, it will be added here. Jerry Tian will try to fix hot air gun, if not successful, he will write email to hakko for help
