The add-on uses a barometer to measure the pressure of the ambient air, from which RE1 then calculates the altitude.
Display the altitude in the OSD to always know how high you are
Use the altitude-hold flight mode
Go all out and combine it with a GPS and an I2C compass to make RE1 fully navigation capable (position hold, loiter, return-to-home, waypoints).
We made RE1 to be extendable and added an extension port with high speed interfaces (SPI, I2C), as well as general purpose signals.
RE1-Baro is the first add-on for RE1 that makes use of the extension port and so can directly stacked on top of RE1 without any wiring, making it easy to use and keeping your build neat and clean.
