FIXME - list required, recommended and optional components

GPS module:
|
|
Supposedly "Install in slot A only" but I think installing on the back would fit better with the OLED. FIXME.

## TODO
|
|
|
|
* Turn off external 3V3 supply when not using GPS to save power!
|
|
> 3V3_S is another 3.3 V power supply, it can be controlled by the MCU in order to disconnect the power sensors during idle periods to save power. 3V3_S is controlled by IO2 pin on the WisBlock Core board.
|
|
Set IO2=1, 3V3_S is on.
|
|
Set IO2=0, 3V3_S is off.
|
|
|
|
* Enable bluetooth
|
|
* Relase as standard part of build (including UF2s)
|
|
* Make this doc into a nice HOWTO: what to order, how to connect (which device in which slots), how to install software
|
|
* Setup battery voltage sensing
|
|
* Set bluetooth PIN support
|
|
* Confirm low power draw
|
|
* Confirm that OLED works
|
|
* send in PR to https://github.com/geeksville/WisBlock for boards define
