Implement in next version:
-
Shunt resistor to measure current draw of coral or of the whole board.
-
Use the same gpiopin for fancontrol as the dev-board
-
Better label output pins.
-
Make connectors asymetrical for good connections.
-
All pins that eventually are needed should be exposed somehow (testpoint or connector)
-
Add LED's to GPIO pins to know their state
-
Add switches or jumpers to power only certain parts of the board
-
Connect Enable pins of Ic's to pin headers or gpios of the processor. In case it is needed it can be used. E.g power supply of SARA chip
-
Add via or tp for everything you eventually want to measure.
-
Place testpoint on vcc on last cap before entering ic.
-
Add gpio level shifter
-
Swap rx tx sara
-
If v0.2 is still mainly for debugging: add buttons for reset and pwr pins: as in this open source project
-
Implement HDMI in first version to be able to debug: Is it even booting up?
-
Make pin connectors for all essential pins: Boot pins, boot configure pins, reset pins, etc: Like this you have the possibility to measure the signal and overwrite it if necessary.
-
First version should just be the coral connectors + power and all necessary things to boot. All other accessories
-
Ask google before starting development what is the absolute minimum bare bones for a working base-board.
