Introducing Adafruit FONA 808 GSM + GPS Shield, an all-in-one cellular phone module with that lets you add location-tracking, voice, text, SMS and data to your project, in Arduino shield format for easy use. Adafruit 2636

7-segment LED display, 1 digit 13.20 mm, black background green (630nm), 10 ucd (10mA), common anode, red (630nm), 6 mcd (10mA), common anode. Pb-free. LED1-AS-B-05219BMRMG

Stepper motor driver with MP6500 system with a potentiometer for current regulation. It allows the bipolar motor to be supplied with current up to 1.5A per phase without the use of a heat sink. Pololu 2967

JST SH type connector, 1.0 mm pitch, surface mounted, horizontal spatial orientation. The set includes 10 connectors

Recognizes the distance of an object away from the sensor up to about 10 inches (~25cm) and the location of the object from side to side across the sensor in about a 6 inch (~15cm) span. You will be able to use I2C or UART to communicate with the ZX Sensor via an Arduino-based microcontroller as well as a computer. SEN-12780

Bluetooth 2.1+EDR module for mounting in SMD technology with a fully configurable UART interface (transfer speed up to 2 Mb/s). SparkFun WRL-12575

Sewable with a 3-pin JST wiring adapter with 3 holes on the board perfect for conductive thread or soldering, wired to a single 3-pin JST-PH Adapter. Sdafruit 2566

Module with ToF VL53L5CX sensor with a matrix of 64 pixels and a range of up to 4 m. Communicates via the I2C interface. Pololu 3417

Touch (resistive, USB) TFT LCD display with a size of 7 inches with a resolution of 800x480 pixels with HDMI interface. Adafruit 2407

Integrated capacitive fingerprint sensor communicating with the external system via the UART interface. The module has a rectangular-shaped sensor field and takes a fingerprint image with a resolution of 160x160 pixels (508dpi). Waveshare UART Fingerprint Sensor (E)

USB - UART converter based on the PL2303TA chip. Compatible with voltages of 3.3 V and 5 V, it has been equipped with a miniUSB connector. Waveshare PL2303 USB UART Board (mini) V2

Adapter for Xbee (ZigBee) radio modules compatible with Teensy 3.1. On the board, the pins of both modules are led out to connectors with a 2.54 mm pitch. SparkFun BOB-13311

This compact board breaks out the pins of a microSD card connector necessary to interface with the card through SPI (Serial Peripheral Interface), and it can be directly integrated into 5 V systems thanks to its on board 3.3 V regulator and level shifting circuity. Pololu 2587

The 8-channel ULN2803A system enables controlling high-current loads from a low-voltage logic level. Adapted for surface mounting, it is used in automation systems, motor control, and microcontroller circuits.

32-bit microcontroller from the STM32L4 family with ARM Cortex-M4 core, 1MB Flash memory, 128kB SRAM, 48MHz, I2C, SPI, UART / USART, USB, CAN, SWPMI, 1.71 ... 3.6V, 100LQFP, STM, RoHS

N-channel 100 V 8.5 mΩ standard level MOSFET in TO220, TO-220, NXP, RoHS

This compact (0.4″ × 0.5″) switching step-down (or buck) voltage regulator takes input voltages up to 50 V and efficiently reduces them to 9 V while allowing for a maximum output current of 600 mA. It has a very low dropout, so it can be used with input voltages that are within a few hundred millivolts of its output.

The Texas Instruments H-bridge allows control of two DC brush motors or one stepper motor. The supply voltage of the motor is in the range of 0-11V, maximum current efficiency 1.5A / bridge. The system has a 12WSON housing

Step-Down DC-DC converter module based on the D36V6F3 system. Input voltage 4 ... 50V, output voltage 3.3V (max. 600mA). Polol 3791
