Seeed Studio 1Sheeld Arduino Shield | DigiKey Daily
DigiKey is proud to offer the 1Sheeld, an Arduino shield to replace all other shields. This shield uses Bluetooth 2.1 to communicate with a specific app on any Android based phone and uses the sensors, switches, LEDs, and wireless capabilities already built into the phone . This allows the Arduino to access all of these items with a single board and a single UART interface instead of requiring separate boards for each feature. With a large amount of virtual shields already created, the 1Sheeld will provide a faster and less expensive way of prototyping your Arduino projects.
