Significant increase in speed for almost the same price of the previous model. Very good workmanship. The Raspi 2 has solved a major problem for me in connection with my predecessor HomeMatic control. There was namely problems with a USB adapter for reading and controlling my Viessmann Vitodens heating. Somehow the old Raspi choked because always something. Maybe it was because he could not make enough power available to the USB port. The Raspi 2 works here now properly with the same power supply (1.2A). My old Raspi is now equipped with the noir camera in the mailbox "displaced" as a receiving camera.
One more thing to the housing. That's because with a relatively large, green overprint of Rydges. In the pictures, however, the impression that the case is completely black. If that matter is, the may, however, strike problems. Usually a Raspi ekes yes rather a shadowy existence in secrecy. But wanted to at least have mentioned.
