• Mika - Selected inputs sensors for dashboard. need to order

• Akshay - Display is chosen, camera in progress. Blocked because current choice wasn’t waterproofed (mb)

• Oscar - given controls leader-daughter which is comprised of dashboard

• Second half of workday - tested motor noise on array (woop woop Ikococator)

Week Plan

• Order display, cameras, lights, compute module

Upcoming Deadlines

BPS:

Upcoming Deadlines

Power Systems:

Updates

• Power board schematic finished! good for review

• Watts and Changxu almost done with an eFuse testboard schematic.

• Shaun got polling test done for I2C BSP. Now working on interrupt based test.

• Devin and Dylan finished contactor driver!!!!! Also finished high level block diagram of batt characterization board.

• Jacob and Tony went through a bunch of edge cases with the Active Precharge board. Did a bunch of considerations into potential current pathways, floating nodes, etc.

• Ravi still working on environmental board layout after several changes. Changes include creating a breakout board for humidity, temp, and airflow sensor. Currently trying to find a connector with a smaller form factor as per emech’s request.

• Bosa and Kaden found a power monitoring chip for power monitoring board.

Week Plan

• order contactor driver and (potentially) eFuse testboard

• order mouser components

• get power board reviewed and start layout

•
