Subcomponent list
12/9
rotating xiao 90 degrees to keep usbc port flush to the edge of the board.
layout awaiting review
need to integrate resistor for led
need write test plan
cam is not secured enough in enclosure
Requirements
RunCam Split 4 V2 - RunCam Store
Runs Arduino software
while in pre recording dormant mode, should draw very minimal power (exact amount will be found in drain timeline)
can detect boost (xiao-rp2040sense has a 6 axis imu built in)
powers camera after boost detection (**5gs for 1/4 second gotta figure that out)
be able to provide power (500ma, at 5V for 20 mins) for the desired recording duration (prob more in case accidentally set off)
(camera will begin recording after power on automatically)
needs to be able to deliver 5V 500maA? to the camera
needs to be able to regulate the voltage going to the cam
needs to be able to illuminate the area intended to capture
+ and - lead going to the LED
+ and - lead to cam
indicator for when the module is on but cam is off and not recording?? (short period and turn off to save power) (if the other
how will it be turned on? just plug it in
Be able to not have issues when jumping exposure from internal to daylight (so have the led bright enough
(stored on an sd card on the camera-board)
will stop power to the cam after 20 minutes
for us this means be able to both turn on and off and not overheat after 20
w if 29/29mm because size of the cam board
*nice to have
be able to connect to serial output of the cam board
if there's room have an i2c breakout??
*
* the board is easily removable from cam board.
*(prob a coding thing) changing sample rate depending on what we want over time
