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.
