* It is engineered as an embedded system that let you develop more projects with the help of Bluetooth technology and different mobile devices. * The RFduino board is powerful enough to run almost any Arduino project and small enough to have full control over 7 GPIO and use it for I2C, SPI, UART, Analog, and more other serial ports. Below you can find a list with all the features included in the small wireless communication board called RFduino. - Size: 15 x 15 x 3.5 mm - CPU: 16MHz ARM Cortex-M0 - Flash memory: 128 kb - RAM: 8kb - Low Supply Voltage: 1.9V - Typical Supply Voltage: 3V - High Supply Voltage: 3.6 V - Transmit Current: 18mA, 4uA ULP - Receive Current: 18mA, 4uA ULP - GPIO: 7
