Another great innovation by our friends at DIY Drones:
The big advance in APM 2.0 is the introduction of the Invensense MPU-6000 sensors, which have an internal Digital Motion Processor (DMP) that does advanced sensor fusion. We’ve tested it for months, including lots of flying, and it significantly outperforms the DCM used in APM 1.0. It’s your choice whether you want to use the MPU-6000 internal sensor fusion or do it yourself in the main processor, but if you choose the DMP it frees up nearly 40% of the processing power in the Atmega 2560. This is a digital chip, so we were able to eliminate the ADC chip used in APM 1.0, lowering chip count along with cost and size.
We’ve also upgraded the barometric pressure sensor to the MEAS MS5011, which has a resolution of 10cm! This is at least twice as accurate as the pressure sensor on APM 1.0 and should give ArduCopter best-of-class altitude hold capability.
You can pre-order the APM 2.0 ($199) on the DIY Drones site.
