ELEV-8 Flight Controller (#80204)
The ELEV-8 Flight Controller is a single-board quadcopter control
solution, designed to control the Parallax ELEV-8 v3 quadcopter
(#80300).
The ELEV-8 Flight Controller features the Propeller P8X32A, a 32-
bit, 8-core microcontroller. Its multicore architecture allows
simultaneous sensor monitoring and motor control, without
interrupts. The ELEV-8 Flight Controller hardware, its C-language
firmware, and the accompanying Ground Station software for
configuration, diagnostics, and live telemetry, are all open source.
This product guide has been updated for the release of the ELEV-8 Flight Controller Rev B. For details,
see Revision History at the end of the document.
Note: This document only covers the Flight Controller Hardware, for information on the Firmware, look
under the Downloads and Documentation section of the #80204 product page.
