With powerful STM32 32-bit microcontroller running at 90MIPs with 128KB Flash and 20KB RAM.
3-axis high-performance MEMs gyros and MEMs accelerometer.
Tiny 36mm x 36mm 4 layer PCB is used for superior electrical noise reduction and flight performance.
Software supports for Windows， Mac and Linux.
Direct and high-speed USB supports with no drivers required， which is a truly plug and play device.
Supports spectrum satellite receiver.
Supports Futaba S-BUS hardware.
Innovative Flexi-port technology is used for superior port flexibility.
4Mbits on-board EEPROM for configuration storage.

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

Superior user experience:
OpenPilot 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 wire harness allows you to connect any standard PWM receiver. A standard mini-USB cable (not included) is used to load the latest firmware and configure everything for your unique airframe.
