OpenPilot CC3D available on HobbyKing
Today they released another great and popular flight controller: OpenPilot CC3D. It is a 32bit controller like HKPilot32 and Naze32. Hardware and software are completely open sourced. You can find more about the project on the OpenPilot website.
The CC3D version is more like the Naze32 Acro. It has the same size 36x36mm and weights only 6 grams. The processor is the same as on the Naze32 – STM32F1. Gyroscope and accelerometer on the CC3D is the popular MPU6000. Both OpenPilot CC3D and Naze32 Acro haven’t any barometer or compass.
So both flight controllers are competitors. The OpenPilot CC3D is priced at 31.99$ and the Naze32 Acro at 24.99$. Although you don’t need to solder any pins on the CC3D. It comes ready to fly. So far HobbyKing is doing great job by offering another open source flight controller.
