9x16 Charlieplexed LEDs designed to match with the Adafruit 16x9 Charlieplexed PWM LED Matrix Driver - IS31FL3731. Color: COOL WHITE.  Adafruit 2974

The module allows you to attach a strain gauge (working in the Wheatstone bridge circuit) and convert the analog signal into its digital representation, available on the module output lines. The system processes the signal with a 24-bit resolution and can be powered by 2.7V - 5.5V. The module is especially recommended for constructing digital scales in combination with Arduino

DRFobot FIT0351-OE

Simple to use stepper motor driver, compatible with anything that can output a digital 0..5V pulse or 0..3.3V pulse. Connect a 4-wire stepper motor and a microcontroller and you’ve got precision motor control! EasyDriver drives bi-polar motors, and motors wired as bi-polar. I.e. 4,6, or 8 wire stepper motors. ROB-12779

2-pin ARK mounting strip, 3.5 mm pitch. 381-3.5-02P-14-00AH. Set of 10 pieces

This add-on board enables a Raspberry Pi B+, Pi A+, Pi 2 or Pi 3 to drive a pair of brushed DC motors. Its dual MC33926 motor drivers operate from 5 V to 28 V and can deliver a continuous 3 A (5 A peak) per motor. The default pin mappings make it easy to get started using our provided software, but the board also exposes most of the driver chips’ I/O pins for more specialized applications. 

An oscilloscope probe designed to analyze signals generated by the ignition coil in car engines. It is compatible with most digital oscilloscopes. Micsig MS-A-008

Photosensor GL5537 50k / 2M. Set of 10 pieces

Neodymium rectangular magnet with dimensions of 15x10mm a and a height of 3 mm. Set of 10 pcs

Troubleshooting tool that communicates between a PC and any embedded device over 1-,2-,3-wire, UART, I2C, SPI, and HD44780 LCD protocols - all at voltages from 0-5.5VDC. Eliminates a ton of early prototyping effort when working with new or unknown chips. TOL-12942

Expansion board for Arduino, allows easy connection of XBee modules, has separate outputs for I2C, SPI and UART buses. The built-in 3.3V voltage stabilizer and operating mode switch make it easier to program the Arduino when the XBee module is connected to the sockets. DFRobot DFR0265
