The Arduino Shield Adaptor offers a way to connect supported Arduino(R) shields to Galago plus a rugged but efficient switch-mode power supply with barrel jack. The board offers compatiblity with 3.3V-friendly Arduino Shields, and may work with some 5V shields depending on their I/O-level and power supply requirements. Check the specs of a shield prior to connecting.

The Bluetooth(R) App Board hosts a Bluetooth module implementing the SPP (Serial Port Profile) connected to Galago's UART. As a low-energy design, it relies on Galago's built-in power-supply. The Bluetooth App Board also features a breadboard-like 0.1" prototyping area that breaks out each Galago I/O pin.
