DD Current Sense / Comms

✅🚹

Any update on the DD Current Sense part selection? Any update on Comms?

• Still working on getting comms set up

• Getting VLAN set up

• Please update DD current sense and comms project ticket with progress updates

• Finish VLAN setup and test

@Farris Matar

PDB/OTS BMS

✅🚹

• Met with PDB crew to discuss Rev 4.1 changes, suggested parts for alternative load switches

  • primary and secondary switches

  • struggling on 17V

• Could do current limiting with the STM

• Planning to assemble SPI LVDS peripheral boards this week, will try to test them as well if possible

• On standby for PDB reviews in future

• Look into current limiting with the STM

• 17V load SW

@Logan Hartford

Lead

✅

• Met with Peter to discuss our subteams goals for the term and somethings we’d like to work on

• Reviewed Austin’s SAR timeline and execution plan and created actionables from that

• Assign all priority 1 tasks for the term

• Reach out to the people on pause and see what their future commitment to the team is

• Update project tickets

PDB

✅🚹

Any updates on PDB Rev 4.1?

• Worked on the 5V layout

• Made slight changes to 17V

• Have a PDB meeting this weekend?

• Please update PDB project ticket with progress updates

@Yuchen Lin

DD Current Sense / Comms

✅

Any update on the DD Current Sense part selection? Any update on Comms?

• Creating DD current sense library components

• Please update DD current sense and comms project ticket with progress updates

• research frequency hopping

• Look into LED matrix

• What is the bare minimum electrical system?

• What are all the all the ways we can achieve this?

• Encoders need 5V, mostly a current ref

  • 20mA per encoder

  • 48-5V buck

• 48V to each motor

Rayaan

• How can this be done?

• How easy of a project is this?

• 3/5 tough

• Use resistors divider board to validate basic functions

  • For checking over-voltage?

• Hook up the cells to the BMS and test basic functions

• Someone has definitely done battery emulation before

  • google it

@Farris Matar (starting next week)

• With vs without the BMS

• What is the safest way?

• What is the most convenient way?

• Any concerns?

• Should always charge it using a battery charger

• Have the BMS hooked up as well

• Connector solution

• Put safety warnings, storage instructions etc

@Yuchen Lin

• Do we have time for a work session this weekend?

• Yes

Rishith

• What exactly does this consist of?

• What needs to be done to verify?

• Send a digital signal to the neopixels, bitshifts

• Just need to hit it with PWM to set the colour of the whole thing

PDB Rev4 - Design and Assemble the PDB

Dec 19, 2022

• Performance testing complete

• Some small schematic and footprint issues across the board

• 17V performed well except on start up

• 5V is very noisey

Science - Assemble & Test

Apr 19, 2023

• Need one or two people to own the assembly and testing of the science boards and work with @Ivan Lim and @Wolfgang Windholtz (Deactivated) to ensure the board is ready for competition.

• Found two assembled boards but none of the parts if @Ivan Lim / @Wolfgang Windholtz (Deactivated) have any ideas please let me know. Otherwise we’ll just order more parts.

• @Ivan Lim / @Wolfgang Windholtz (Deactivated) Both of the assembled boards are missing a lot of parts, do the boards have a bunch of population options?

@Farris Matar

SPI LVDS - Assemble and Test

Apr 19, 2023

• SPI LVDS Host boards should have been assembled

• SPI LVDS Peripheral parts and boards should be in the bay now, pending assembly

• Harnesses need to be ordered in order to wire them up together and do testing
