The Bluefruit LE UART Friend makes it easy to add Bluetooth Low Energy connectivity to anything with a hardware or software serial port. Adafruit even have nice hardware flow control so you won't have to think about losing data. Connect to your Arduino or other microcontroller or even just a standard FTDI cable for debugging and testing.This multi-function module can do quite a lot! For most people, they'll be very happy to use the standard Nordic UART RX/TX connection profile. In this profile, the Bluefruit acts as a data pipe, that can 'transparently' transmit back and forth from your iOS or Android device. You can use our iOS App or Android App, or write your own to communicate with the UART service.So it's a fancy pants Wireless UART Adapter?The board is capable of much more than just sending strings over the air! Thanks to an easy to learn AT command set, you have full control over how the device behaves, including the ability to define and manipulate your own GATT Services and Characteristics, or change the way that the device advertises itself for other Bluetooth Low Energy devices to see. You can also use the AT commands to query the die temperature, check the battery voltage, and more, check the connection RSSI or MAC address, and tons more. Using the Bluefruit iOS App or Android App, you can quickly get your project prototyped by using your iOS or Android phone/tablet as a controller.Technical Details ARM Cortex M0 core running at 16MHz 256KB flash memory 32KB SRAM Transport: UART @ 9600 baud with HW flow control (CTS+RTS required) 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 to get up and running quickly Dimensions: 21mm x 32mm x 5mm / 0.8'' x 1.26'' x 0.2'' Weight: 3.4g

16 Channel Servo-HATPWM up to 1.6 KHz12-bit accuracyWorks with any servo that can be driven at 5V and receives 3.3V logic level signalsDimensions: 65 x 56 x 13 mm

With these Shield you can saving data to files on any FAT16 or FAT32 formatted SD card, to be read by any plotting, spreadsheet or analysis program. SD card interface works with FAT16 or FAT32 formatted cards3.3 V level shifter circuitry prevents damage to your SD cardfor the Prototyping area with soldering connectors, circuitry or sensorsOnboard 3.3 V regulator is both a reliable reference voltage and also reliably runs SD cards that require a lot of power to run
