3. Raspberry Pi Telephoto Lens

The official Raspberry Pi telephoto lens, compatible with the HD camera to photograph distant elements thanks to a 16mm focal length.

4. Adafruit Motor/Stepper/Servo Kit V.2

Control two servos, four bidirectional DC motors and two stepper motors with your Arduino developer board. The Arduino Motor Shield has a TB6612 controller and requires a separate power supply. Thanks to the stackable design, you can run multiple shields on the same developer board. This allows you to control up to 64 stepper motors or 128 DC motors. 

5. Velleman SV3N Subminiature Buzzer 8-15Vdc

Velleman SV3N, subminiature buzzer, 8-15VDC, 15mA, 88 dB, wire connection, 12mm high, flange mounting, continuous tone, 3.3kHz, ABS housing.

6. Adafruit HUZZAH32

The HUZZAH32 is a ESP32-based Feather, made with the official WROOM32 module. It's packed with everything you love about Feathers: built in USB-to-Serial converter, automatic bootloader reset, Lithium Ion/Polymer charger, and just about all of the GPIOs brought out so you can use it with any of Feather Wings.

That module nestled in at the end of this Feather contains a dual-core ESP32 chip, 4 MB of SPI Flash, tuned antenna, and all the passives you need to take advantage of this powerful new processor. The ESP32 has both WiFi and Bluetooth Classic/LE support. That means it's perfect for just about any wireless or Internet-connected project.

Because it's part of a Feather eco-system, you can take advantage of the 50+ Wings that are designed to add all sorts of cool accessories.

The ESP32 is a perfect upgrade from the ESP8266 that has been so popular. In comparison, the ESP32 has way more GPIO, plenty of analog inputs, two analog outputs, multiple extra peripherals (like a spare UART), two cores so you don't have to yield to the WiFi manager, much higher-speed processor, etc. etc!

Please note: The ESP32 is still targeted to developers. Not all of the peripherals are fully documented with example code, and there are some bugs still being found and fixed.
 

7. Adafruit LIS3DH Triple-Axis Accelerometer

(+-2g/4g/8g/16g)

8. OEM Bluetooth 4.0 USB modules (v2.1 back-compatible)

This adapter is backward compatible to v2.1 and earlier, but also supports the latest version 4.0/Bluetooth Low Energy. Inside is a CSR8510 Bluetooth USB host. Drivers for CSR Bluetooth modules are integrated in Windows XP/7/8/10. You don't need to install any software or download anything: other Bluetooth drivers or stacks like BlueSoleil are not as good as the Windows stack and cause problems. Just plug it in and let go. Windows will automatically install the BT driver, it may take a few minutes.

9. Adafruit Bluefruit LE SPI Friend Bluetooth Low Energy (BLE)

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).

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.

If you like Serial communication more than SPI, we also have a version that can talk UART

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. Really, way too long to list here!

Download our free Android/iOS app and you're ready to rock!

Using our Bluefruit iOS App or Android App, you can quickly get your project prototyped by using your iOS or Android phone/tablet as a controller. We have a color picker, quaternion/accelerometer/gyro/magnetometer or location (GPS), and an 8-button control game pad.

You can do a lot more too!

The Bluefruit can also act like an HID Keyboard (for devices that support BLE HID)
Can become a BLE Heart Rate Monitor (a standard profile for BLE) - you just need to add the pulse-detection circuitry
Turn it into a UriBeacon, the Google standard for Bluetooth LE beacons. Just power it and the 'Friend will bleep out a URL to any nearby devices with the UriBeacon app installed.
Built in over-the-air bootloading capability so we can keep you updated with the hottest new firmware. Use any Android or iOS device to get updates and install them!
Why use Adafruit's Module?

There are plenty of BLE modules out there, with varying quality on the HW design as well as the firmware. So why should you go with this one?

One of the biggest advantages of the Adafruit Bluefruit LE family is that we wrote all of the firmware running on the devices ourselves from scratch. We control every line of code that runs on our modules ... and so we aren't at the mercy of any third party vendors who may or may not be interested in keeping their code up to date or catering to our customer's needs.

Because we control everything about the product, we add features that are important to our customers, can solve any issues that do come up without begging any 3rd parties, and we can even change Bluetooth SoCs entirely if the need ever arises!

10. Adafruit Neopixel Stick

Use only one microcontroller pin to control as many as you can daisy chain together! Each LED is addressable because the driver chip is inside the LED. Each has a constant current drive of ~18mA, so the color stays very constant even if the voltage varies, and no external choke resistors are needed, making the design slim. Power the whole thing with 5VDC (4-7V works) and you're ready to rock.
