Flexi-port gives CopterControl the flexibility to use either I2C and a single serial port or dual serial ports, according to your connectivity needs.Superior user experienceOpenPilot 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 CopterControl boards are tested before shipping and come with bootloader already flashed. A standard mini-USB cable (not included) is used to load the latest firmware and configure everything for your unique airframe.The OpenPilot project, whist still young, it trying to make Open Source much more user friendly. OpenPilot software is designed to be used by everybody! 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!Sensors and Components3-axis Gyroscope array and 3-axis Accelerometer: MPU-6000Supports several common RC inputs: 6 PWM channels, combined PPM, Spektrum/JR DSM2, DSMJ, DSMX satellites, and Futaba S.Bus receivers.Simultaneous support for multiple receivers.ReceiverPort functions (configurable): 6 PWM input channels or combined PPM stream, 4 PWM output channelsMainPort functions (configurable): serial telemetry (default), GPS, S.Bus, Spektrum/JR satellitesFlexiPort (configurable): serial telemetry, GPS, Spektrum/JR satellites, or I2C peripherals (under development)10 PWM outputs to servos or ESC’s, or for camera stabilizationCamera stabilization: supports up to 3-axis camera mounts with stabilization and manual control from any of configured receivers.Onboard USB connectivity for easy configuration.USB and serial telemetry and configurationSupported by powerful OpenPilot GCS4 Mbit onboard memory3C Quaternion based complementary filter running at 500HzPackage size: 9 * 4 * 2cm / 3.5 * 1.6 * 0.8inPackage weight: 15g / 0.5ozNote:Color: white and black (delivery randomly).Package list:1 * CC3D Flight Controller w/ CablesPackage List:1 * CC3D Flight Controller w/ Cables
