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. https://docs.rakwireless.com/Product-Categories/WisBlock/RAK1910/Overview/#product-description
ST LPS22HB baro & temp sensor, i2c address 0x5c https://docs.rakwireless.com/Product-Categories/WisBlock/RAK1902/Overview/#product-description https://www.st.com/en/mems-and-sensors/lps22hb.html https://www.st.com/resource/en/datasheet/lps22hb.pdf
OLED https://docs.rakwireless.com/Product-Categories/WisBlock/RAK1921/Overview/#product-features Must be installed on the front for the I2C wires to lineup

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
