The CC3D provides a crisp feel when flying tricopter, quadcopter, hexacopter, octocopters, and even fixed-wing planes. CC3D Copter Control Hardware

Features:

Powerful STM32 32-bit microcontroller running at 90 MIPS with 128KB Flash and 20KB RAM.
3-axis high-performance MEMs gyros and 3-axis high-performance MEMs accelerometer.
Tiny 36mmx36mm 4 layer PCB for superior electrical noise reduction and flight performance.
Software support for Windows, Mac, and Linux.
Direct high-speed USB support with no drivers required, a true plug and play device.
Spectrum satellite receiver support.
Futaba S-BUS hardware support.
Innovative Flexi-port technology for superior port flexibility.
4Mbits onboard EEPROM for configuration storage.

Flexi port:

Copter Control also offers innovative Flexi-port, which provides either I2C connectivity or a second serial port. Flexi-port gives Copter Control the flexibility to use either I2C and a single serial port or dual serial ports, according to your connectivity needs.

Superior user experience:
Open Pilot has tried to make your experience with the CC3D as easy and trouble-free as possible. Naturally, for a high-end product, the hardware is complete; there is nothing to solder. The included RC harness allows you to connect any standard PWM receiver. All Copter Control boards tested before shipping and come with bootloader already flashed. A standard mini-USB cable (not included) used to load the latest firmware and configure everything for your unique airframe.

The Open Pilot project, whilst still young, it trying to make Open Source much more user-friendly. Open Pilot software designed to be used for all major operating systems are supported and install packages are provided. The software is all free software under the GPLv3 license and not only are you welcome to hack it, but we encourage it!
