3xUART - Ethernet converter enabling two-way communication between devices equipped with UART TTL ports and the Ethernet network. It is visible in the system as a virtual COM port and configured via the website or using AT commands. USR-TCP232-ED2

UART-Ethernet converter for bi-directional communication between devices equipped with UART TTL ports and Ethernet. It is visible in the system as a virtual COM port and configured via a web page or via AT commands. USR-K5

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. 

Module with 15 QTRX type optocoupler with analog output. The module operates from 2.9 V to 5.5 V, detects objects at a distance of up to 50 mm. The sensor will be used in projects that require detection of changes in the ground, e.g. in linefollower robots. Pololu 4415

This discrete MOSFET H-bridge motor driver enables bidirectional control of one high-power DC brushed motor. The small 1.3″ × 0.8″ board supports a wide 6.5 V to 30 V voltage range and is efficient enough to deliver a continuous 25 A without a heat sink.

The DS3231 Real Time Clock (RTC) module with CR2032 battery is a precise and reliable I2C enabled component that provides time and date tracking, maintains accuracy when main power is disconnected, and offers alarm and wake-up functions with easy connectivity to various platforms such as such as Arduino, Raspberry Pi or STM32

ARK terminal connector spring 4-pin, pitch 3.81 mm, non-detachable

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.
