This module contains a 5050 RGB LED. Connect this module to the Arduino PWM outputs to generate a full range of colours. Warning! This module does not include current limiting resistors! Damage to the LEDs will occur if connected directly to 5 V.

Stepper motor driver board

This module uses a 3-channel MOS switch similar to a relay element. Use it to drive a servo, high current LED strips, and more! Four 3 mm holes are provided so you can mount the module onto other devices.

The Whadda VPM400 Module. This 4-channel relay interface board can control various appliances and other equipments with high current. It can be controlled directly by any micro-controller.

This module converts the microcontroller's power supply into a higher, adjustable voltage.

3-40Vdc Input to a 1.25-35Vdc Output with a maximum input current of 2.5A

A simple single relay switch for 5Vdc Arduino operation. SPDT 10A contacts.

A simple MOSFET switch/driver. 3-5Vdc input and max ouput of 0-24Vdc

This breadboard 3.3V / 5V power supply module fits the power rails on most breadboards. It also features a mini USB power port to supply power to external devices.

This Arduino add-allows you to use the Arduino as a DMX master device (transmitter). This board is a simple circuit based around a driver chip (MAX-485 or SN 75176). With XLR 3 pin male DMX output connector. Pin1 = Signal Common, Pin2 = Data-, Pin3 = Data+ The board converts the Arduino signal voltage according to DMX (RS485). Impedance is 100 Ohm.
