Current Model of Project
Todo for week 4
Find similar boards with the function that we want (read analog input and send result to computer)
Decode what is needed from the board to make it function
Give sample code found to the software team
Create a PCB components list to run by the rest of the team
1/20/2025
Goals:
Battery powered and working form factor prototype.
Todo List for Week 3:
Create new board design with:
- Adding buttons to program
- Create a connection point for the battery
- BMS board sourced/created
- Find a better way to connect all the boards together/modify current connectors
Clear comments for how put the board together / setup to be ordered
1/26/24
Currently completed the following tasks
- Adding buttons to program
- Create a connection point for the battery
- BMS board sourced/created
- Find a better way to connect all the boards together/modify current connectors
Week 4 to do
Simplify the board:
- Talk with the software team on having only one esp32 to take mic inputs
- Make a design with only two esp32, including the one for the camera
- Make version where the camera is connected to the board through is ribbon cable
- Find battery charging circuit to incorporate
2/1/24
- Currently completed the following tasks
- Made design that only uses one ESP32 to take the mic inputs
- Made adapter board for the ESP32
- Found possible BMS boards that could be used
- looked into the possible ribbon cables that can be used to connect the boards
Week 5 to do
- Talk about the configuration of pins with the software team
- Look at availability of parts that can be selected
- select and do fine tuning the PCB traces and placement
- Work on requirements and slides for CDR
2/14/25
Made a list of the new pins that will be used for the I2S bus to the other board
Reworked board to use in stock parts (same mics from last year)
Presented current state of the project at CDR
to-do
Start working with software team to get all mics to work off on one esp32
Label the board in a more comprehensible way for pinouts and connections
Label the schematic
Order the boards
3/1/25
Order the boards
Label the board so the connections are more clear
to-do
Work on possible alternative board for future designs (smaller PCB, different connectors)
Label the schematic
3/8/25
Labeled the schematic, grouped similar components together, and rearranged the pages to be more of how the final product will look
Started work on a smaller design
Bounced around options for BMS boards that can be used.
Checked on boards production status
to-do
Switch over to software to start getting all 4 mics to work on one ESP32
Start documenting some of the work on how to put the boards together
Wait for the boards
3/16/25
Starting the switch over to software, looking over what we already have working
Got the boards images onto the GitHub with new files
to-do
Get two mics to work off of one ESP32
