OpenPilot CC3D Revolution Flight Controller Upgrade Version Integrating OPLinK Revo

Description:
- The OpenPilot Revolution board, also called 'Revo', is a new breed of Autopilot using the STM32F4 series, 210MIPS ARM Micro-controller. This is important, as it contains a hardware floating point unit (FPU), which is a huge advancement for hobby-class autopilots. Of course, OpenPilot has been 32bit since day one, and the FPU is another step up the performance ladder. The FPU allows precise, low-latency processing of real-life measurements using advanced attitude estimation algorithms.
- The Revolution is a flight control computer with autopilot, intended for multirotors, helicopters and fixed wings. It is a full 10DOF with gyroscope, accelerometer, magnetometer and pressure sensors.
Technical description
CPU
- CPU is the STM32F405RGT6 chip, with ARM Cortex-M4 core at 210MIPS, FPU, and saturation arithmetics DSP functions.
- The chip features a range of built-in hardware modules that can bo programmed once and function independently, requiring little to no CPU overhead. These include 14x multichanel timers, 3x synchronous-sampling ADC serving up to 24 channels, 2x DAC, matrix memory controller with 16-stream DMA, and other. Communication modules include USB2.0, 3x I2C, 3x SPI, 4x USART, 2x CAN and SIDO. All these modules can be configured for accessing the chip pins using a flexible switch matrix, or disabled to save power.
- It even contains a real time hardware calendar if you want a wake up flight.
- The software and settings are loaded through USB connector and no-hassle update function in the GCS (Ground Control Station).

Modem
- The board features a built-in 433MHz OPLink Modem.

Dimensions
- OpenPilot products use the standard OpenPilot footprint, and hence has the same dimensions and mounting holes as the OpenPilot CC. CC3D, Revo, GPS, OSD and PipX boards.

Ports:
- Servo 1-6: These are the PWM outputs that go to servos or electronic speed controllers (ESCs).  Power for the flight controller is typically supplied through these headers from only one of the ESCs, but in most cases, all the servo wires can be left connected. Cutting the pin from servo wires is highly discouraged.  If you feel you must disconnect three of the hot wires, use some shrink tube or electrical tape to insulate the removed pin (you may need that positive voltage at a later date!).  The positive (Vcc) and negative (Gnd) pins are indicated on this diagram and the board. In rare cases, you may need to also disconnect the ground pin if your ESCs are creating ground loop problems (indicated by a general weirdness in setup).  (see the CopterControl - CC3D -Atom Hardware Setup page, Power section, for instructions on how to remove and insulate the extra pins)
