Adafruit Bluefruit LE SPI Friend - Bluetooth Low Energy (BLE)

SKU : A16030 DESCRIPTION Would you like to add powerful and easy-to-use Bluetooth Low Energy to your robot, art or other electronics project? Heck yeah! With BLE now included in modern smart phones and tablets, its fun to add wireless connectivity. So what you really need is the new Adafruit Bluefruit LE SPI Friend! The Bluefruit LE SPI Friend makes it easy to add Bluetooth Low Energy connectivity to anything with 4 or 5 GPIO pins. With SPI, you don't have to worry about baud rates, flow control, or giving up a hardware UART port. Connect to your Arduino or other microcontroller using the common four-pin SPI interface (MISO, MOSI, SCK and CS) plus a 5th GPIO pin for interrupts (to let the Arduino know when data or a response is ready). TECHNICAL DETAILS ARM Cortex M0 core running at 16MHz 256KB flash memory 32KB SRAM Transport: SPI at up to 4MHz clock speed 5V-safe inputs (Arduino Uno friendly, etc.) On-board 3.3V voltage regulation Bootloader with support for safe OTA firmware updates Easy AT command set tunneled over SPI protocol to get up and running quickly 23mm x 26mm x 5mm / 0.9\ x 1\ x 0.2 nWeight: 3g
