Priority I Tasks:

Task	Discussion Questions	Answers	Assigned To

Task	Discussion Questions	Answers	Assigned To
Get the bare minimum electrical systems working for the drive train to be able to move	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
Validate the OTS BMS	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 (Deactivated) (starting next week)
Create a SOP document for how to charge the LiPo battery pack	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
Complete Rev 4.1 of PDB	Do we have time for a work session this weekend?	Yes	Rishith
Validate the electrical functionality of the LED matrix	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 arduino town	David Choi / Rishith / Farris Matar (Deactivated)
Set up 900 Mhz and 2.4 Ghz bands

PDB	Rishith Bomman (Deactivated) / Farris Matar (Deactivated) / Rayaan	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	HIGH
BMS	Joshua Harper / Ari Wasch (Deactivated) / Olivia	BMS - Design and Assemble the BMS	Apr 19, 2023	One BMS has been assembled Basic non-performacne and non-firmware tests have been done An off the shelf replacement is being sourced	HIGH
Comms	Yuchen Lin / Logan Hartford (Deactivated)	Comms	Oct 31, 2022		HIGH
Science		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 (Deactivated) and Wolfgang Windholtz (Deactivated) to ensure the board is ready for competition. Found two assembled boards but none of the parts if Ivan Lim (Deactivated) / Wolfgang Windholtz (Deactivated) have any ideas please let me know. Otherwise we’ll just order more parts. Ivan Lim (Deactivated) / Wolfgang Windholtz (Deactivated) Both of the assembled boards are missing a lot of parts, do the boards have a bunch of population options?	MEDIUM
SPI LVDS	Farris Matar (Deactivated)	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	MEDIUM
RS422	David Choi / Farris Matar (Deactivated)	RS422 - Assemble and Test	Apr 19, 2023	Farris Matar (Deactivated) verified the design and was able to send data using the boards 3 Boards have been assembled and tested	MEDIUM
LED Matrix		LED Matrix 2022/23	Apr 19, 2023	LED matrix has been located Should work, just needs power and a PWM signal	MEDIUM
Digital Display Current Sense Board	Olivia Markham / David Choi / Yuchen Lin	Current Sense Display	Apr 19, 2023	Currently in the schematic design phase of the project	LOW
