| "VEX V5 Smart Motor - VEX 276-4840, This V5 Smart Motor is an extremely powerful unit that puts an integrated encoder and a motor controller into one compact package. You can customise speed and torque performance with interchangeable gear cartridges (shipped with 18:1 200rpm standard gear cartridge, further cartridges available separately). A new method of power management has been developed, ensuring that the V5 Smart Motor always gives consistent performance. The motor runs at a slightly lower voltage than the batteries minimum voltage, and the motor's power is accurately controlled to +/-1%. This means the motor will perform the same for every match and every autonomous run regardless of battery charge or motor temperature. VEX V5 Smart Motor"

| "Adafruit Stereo 2.8W Class D Audio Amplifier I2C Control AGC - Adafruit 1712, The Adafruit Stereo 2.8W Class D audio amplifier features AGC (Automatic Gain Control) and an I2C interface. The I2C link lets you control the AGC parameters such as the gain, compression ratio and others, plus it lets you switch each channel on and off. There's a shutdown pin to put the amplifier into a hibernate mode where it consumes only a tiny 0.2µA. There are 1.0µF capacitors on the input channels making them differential, the R- and L- pins can be tied to ground if you don't have differential inputs. The amplifier is intended to drive speakers directly as it outputs 300kHz PWM which the speaker coils average out. That may seem like an odd idea, but the high frequencies cannot be heard. The outputs are Bridge Tied for direct connection to the speakers. The I2C connection is compatible with 3.3 or 5V logic as it has its own separate supply from the main amplifier.Supplied as a fully assembled board, including the 1.0µF capacitors plus 2 x 2-pin screw terminal blocks for the speaker connections and a 1 x 10-pin strip of 0.1in. male header pins for you to solder as needed.

Send and receive SMS messages and GPRS data, make and answer phone calls, and listen to FM radio. In fact enough functions to build a working phone, including driving a vibration motor and recharging a LiPo battery from the USB power. The board needs a microcontroller to drive it and will work with anything that can send and receive serial data, from an Arduino to a Raspberry Pi. Adafruit's example wiring uses only 4 x microcontroller pins, though you can probably get by with just Tx/Rx. Adafruit have an FONA tutorial which demonstrates how to wire them up and interact with them using the AT command set from a serial terminal. While you're developing your application you can use a serial terminal to send commands and get responses so that you can see exactly what's happening.Supplied as a fully assembled board plus a 1 x 16 strip of 0.1in. male header pins for you to solder as required. You will also need a microcontroller with a serial UART (3 to 5V compliant), a 2G mini SIM card (15 x 25mm) to connect to a mobile network, a LiPo battery, a micro-USB cable to charge the battery and an external antenna with an SMA connector.
