Closed mattbrejza closed 8 years ago

mattbrejza commented 8 years ago
Item Notes Progress
LGA12/LGA14 footprints mirrored Re-routing also needed
switch A/B and joystick
Add option to bypass battery protection if not fitted
remove HSE and wire touchscreen touchscreen not yet confirmed. if connecting touchscreen, make sure goes to ADC2, leaving ADC1 for user
thinking we should move the LED to the bottom of the board/below the SD socket, so its not in you hand when you hold the badge; move 5mm LED more inwards
Move A, B LEDs away from screen
Add reset button for STM? same switch as MENU?
X3 is long way from mcu, check ok ✔ - its only 32kHz, and not that far
Can we get ic4 in something other than msop-10? ✔ nope
Test pad add more add testpoints to parallel control sigs + one data ✔
Speaker too close to the edge
Move the CC serial header so its not under the screen
consider switching PA5 and PE11 for DAC on external headers
consider connecting WS2812 to a timer pin
do something with the 11 way connectors so they are in something we can buy and does not need modifying pin header socket size are normally 2,3,4,5,6,8,10.15,16,20,25
Check if WS2812 is fine on 3.3V, otherwise move to Vbat
Check meander on usb trace ✔ close enough
Battery option 3
R23 sort out
Test point on CC_HIB
