A Raspberry Pi can be the foundation for a home automation hub, connecting smart devices and sensors. You might use it to manage lights, adjust a thermostat, or even track energy consumption.

PiConsole-BT works with Bluetooth 2.1 enabled smartphones, tablets and PCs. You can get instant access to the Raspberry Pi Serial Console from your Mobile device. (also includes USB).

While the Raspberry Pi has very good support for an I2C bus, a lot of very cool chips – including the in system programmer for just about every ATtiny and ATmega microcontroller – use an SPI bus.
