OpenPilot have created a new generation of powerful, low cost flight controller known as CC3D Revo, that is suitable for multirotors, helicopters and fixed wing aircraft.
The Open Pilot CC3D Revolution (Revo) is the result of 1000's of hours of R&D done by the open source community, for the benefit of hobbyists and provides a robust base for commercial, research and hobby projects alike.
The Revo flight controller features state of the art hardware and software, backed by the Open Pilot GCS System and boasts position hold and 3D waypoint navigation amongst its many other features. It is a full 10DOF controller with built-in gyroscope, accelerometer, magnetometer and barometric pressure sensors.
The Revo uses the STM32F4 CPU which uses a hardware floating point unit (FPU,) that represents a huge advancement for hobby-class autopilots. This FPU allows precise, low-latency processing of real-life measurements using advanced attitude estimation algorithms. In addition to an integral FPU, the STM32F405RGT6 chip has the ARM Cortex-M4 core at 210MIPS and saturation arithmetic DSP functions.
The CPU has a range of built-in hardware modules that can be programmed once and function independently ,requiring little to no CPU overhead. These include 14 multi-channel timers, 3 synchronous-sampling ADCs serving up to 24 channels, 2 DAC, matrix memory controller with 16-stream DMA. Communication modules include USB2.0, 3 x I2C, 3 x SPI, 4 x USART, 2 x CAN and SIDO. All these modules can be configured for accessing the chip pins using a flexible switch matrix, or disabled to save power. USB connectivity ensures that software updates and settings are straightforward to make in the GCS (Ground Control Station.)
The flight controller features a built-in 433MHz OPLink Modem and uses the standard OpenPilot footprint so has the same dimensions and mounting holes as the OpenPilot CC, CC3D, GPS, OSD and PipX boards.
The Revo has an incredible array of functions to manage all of your flight parameters, and while it doesn't have the kitchen sink, it does a real time hardware calendar if you ever feel the need for a wake up flight!
