Active PCB Projects

High Current Power Module (Taim, Steven)

  • @Taim Al-Dabbagh @Steven Wang

  • Discussion on using both sides of the board.

  • Reconsidering some of the components such as shunt resistor, inductors.

    • Downsizing components in-order to make the board smaller.

    • Please document.

  • Would like to have schematic, layout, routing done by end of this term.

12S ESC (Ethan, Chris)

  • @Ethan Abraham @Christopher Chung

  • Please update

6S ESC (Rayyan, Mostafa)

  • @Rayyan Mahmood @Mostafa Hussein

  • Mostafa: No updates this week

LED Controller (Neel, Parker)

  • Met on Saturday and split up on what to research for component selection.

  • Neel is LED selection and Parker is responsible for timing circuit.

  • Circuit schematic and prototype this term and then board design next term.

  • Will meet Sunday @ 6.

ELRS Gemini (Michael, Farris)

  • Jerry came in on Saturday and reflowed the solder.

  • Farris is debugging and most of the work is now on firmware team.

Drone Battery PCB (Farris)

  • @Farris Matar

  • Not much progress.

PDB (Tom)

  • Majority of technical details related to choosing voltage divider values into ADC figured out after taking into account the equivalent circuit in the ADC that contributes to the input impedance.

  • Finishing up LTspice simulation to try to validate proper equivalent input impedance after taking into account the shottky diode and low pass filter.

  • Still trying to figure out pros and cons in deciding to put RPP across the input voltage from the batteries or just the input into the 5V and 12V buck regulators.

Tracking Antenna (Nolan, Hardy, Michael)

  • Nolan: will work on overcurrent protection (already designed) and implement into schematic.

  • Hardy: Working on 1:1 connection between Nucleo and PCB board, major progress. Fixing connector schematic for peripherals such as UART and SPI.

  • Michael: working on overcurrent protection. @Michael Botros fill in later.

  • Goal to have schematic done by next EE meeting and then move on to placement and routing.

12S Servo Module (Jerry)

  • Routing is complete but missing a lot of details, received comments from Daniel and will address them this week. Board should be complete & ready to order before next EE meeting
