Please update test plans/board documentation!

Bring-up Tasks

In order of priority.

• CAN DSHOT Controller

  • ESC CAN Adapter Test Plan

• Tracking Ant Controller

  • https://uwarg-docs.atlassian.net/wiki/x/CQA7ow

  • PRIORITY ASAP

    • EFS person bust so we have bought a little time

  • Issue with buck IC

    • Enable pin not working?

    • QFN package causing issues

    • LDO into Buck is working - subsequent systems not working

    • More debugging to come

  • Maybe a short?

  • More testing today, feel free to come!

• RPi Interface Rev B

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

  • 2 boards assembled and tested

  • Daniel Puratich for details

  • rpi rev b needs software to validate uart killswitch, power is all working as expected on both boards, plz relay to autonomy

• 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

Action Items

...

• Jerry’s 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
