Single Servo Driver

  • Buck and LDO confirmed to be working. Load and efficiency testing completed, looks good. Load transient testing in progress

  • blocked by firmware people right now ..

Load transient testing → EFS Firmware testing

6s Power Module

  • Both sides assembled

  • Still needs some cleanup with connectors and AFE chips

  • Some small rework fixes but mostly good to go for firmware

  • Needs firmware for other side to do voltage and current sensing using the AFE chips

 

Peggy 2/Comp Updates

  • @Jerry Tian For Peggy 2

  • Did not make progress

  • Tracking antenna, water controller on order

  • Single servo on firmware

  • This week working on pi harness

    • Giving out to pi rev c people

  • make harness schem on tinycad

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

  • The below boards should be included

    • 6S servo module rev 2 - On midterm order - assembly likely next term

    • Single Servo Driver - waiting on EFS

    • 6S power module - in validation @Andrew Chai for details

      • POR for first flight of eclipse next term.

    • CAN Integration 2025

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 @Anthony Lazar @Anthony Luo @Shawn Yang

    • Update: Handing off layout to @Kenny Na !! Goal is done end of term

    • End of term target

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

    • @Ethan Abraham Individual Contributor

    • Knowledge transfer done with @Andrew Chai

    • Did initial placement for MCU + Power + Gate Driver

    • Will need to put more thought into FETs - most likely will require some cooling system since most FETs on Digikey within a reasonable price will not be able to handle the operation conditions at ambient temp

    • Will consult with Kevin and Ethan regarding further steps and some feedback on initial placement

    • End of term target

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

    • @Nolan Haines Individual Contributor

    • layout is like 95% done, doing silkscreen and the final touches
