A quick look at Parallax's new Elev8-FC flight controller.
Hardware includes a Parallax Propeller, an LSM9DS1 gyro/accelerometer/magnetometer, a WS2812B status LED, LPS22H barometric pressure sensor, 8 remote inputs, 6 ESC outputs, I2C I/O header, WS2812B output (for chaining LEDs), an expansion port, and a piezo speaker.
Includes open source code to drive it all, with resources left over for user code and experimenting.
I bought a body shell for a Phantom 1, mounted the Elev8-FC to it, and it flies like a champ. If you don't believe me, you can tell it's not a Phantom by the blink pattern of the LED. :-)
