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

## TODO

> 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.
