Active PCB Projects

High Current Power Module (Taim)

• @Taim Al-Dabbagh

Calculated/set target current density of 30A/mm^2, need to verify using PDN Analyzer

Battery Elimination Circuit

• @Ishman Mann

• Has researched the PCB

• Researching Current Sensoring

12S ESC (Mena)

• @Mena Azab

  • Busy this week as well. most likely start on this in March

• need to work on

  • Field oriented control firmware setup to know MCU pinout

  • microcontroller schematic

  • gate driver schematic

6S ESC (Rayyan, Mostafa)

• @Rayyan Mahmood @Mostafa Hussein

• Rayyan: Power FET selection completed with updated calculations. Gate driver components mainly done. Hope to have gate driver component selection done by next week\

• Mostafa is creating components for his buck circuit

LED Controller (Neel, Parker)

• @Neel Patel @Parker Lawrence-Valeriani

• First iteration has been assembled and handed off to firmware

• No progress this week on the second iteration

• Iteration 2 will target the header issue as well as errors discovered during assembly (missing identifiers, poor silk screen, etc)

• Trouble programming mcu

PDB (Tom)

• @Tom Chiu

• Updated a new selection of buck converters for higher current output in my excel sheet in the voltage regulator options section: Part Selection Options - Google Sheets. Would anyone be free to discuss it sometime over the weekend? @Jerry Tian To set up call

• Will do a bit more research before then in terms of thermal calculations, some seem more complicated than the others.

Tracking Antenna (Nolan, Hardy, Michael)

• @Nolan Haines @Hardy Yu @Michael Botros

• Michael had made progress on routing

ZP3 Rework (Anthony, Ryan)

• @Anthony Zhelnakov @Ryan Scomazzon

• IMU + magnetometer will be included

• Component selection is finished, should be finished.

• Using ICM-20948 IMU - Is cheap and common, has built in magnetometer, although needs LDO.

• Jumpers will not be needed

Capacitor Analysis for Drone (Anthony)

• @Anthony Zhelnakov

• Has done some research

CAN Interface Board (Hardy)

• @Hardy Yu

Hardy will finish MCU selection before next week’s EE meeting.

Drone Harness (Neel)

• @Neel Patel

• Need to shorten power harness on Pegasus

  • @Anthony Zhelnakov Will make shorter Power Harness only + configuration

• Houston wiring needs to be cleaned up

• Make VTX harnessing better ie. less janky

• Make Harnessing Diagrams

  • Altium

Diversity Gemini ELRS , RF project

• @Nolan Haines

needs assessment: better telemetry TX from the drone

4 antennas + 2 frequencies

• I am taking on this project

• Still in very early stages of project definition + research

Flight Test

• No flight test for 3 weekends
