Expand Hardware Overview with common details

beriberikix commented 9 years ago

It would be great to flush out the Hardware Overview and add details that your typical maker might need to know. Some of it is buried in the datasheets and some is board-specific. Some of its on the pinouts and some of its in the text below. It would be awesome to at least have it all in one table. Details that come to mind include:

Max current per I/O pin
Total supply current for all I/O pins
voltage tolerances per pin (any 5v tolerant?) Currently shown only on the image and for only half the board
analog voltage ranges
max analog value/resolution
PWM resolution & freq
Pull-up/pull-down resistors? Resistance?
pins/registry used by user led & button
vin voltage range
details about the RTC, like accuracy or if uses a separate chip

I'm sure there's other details that would be useful but that's all I got for now. I made a kinda popular pinout for the Spark Core that the team now uses in their docs and would be interested in doing the same for the Armstrap if I could have the right data.

Thought of another interesting datapoint - the breakdown of ADC free for the user vs used by peripherals.

Reading the Eclipse samples, it looks like USER LED is on GPIOC Pin 1 and USER BUTTON is on GPIOC Pin 0.
