A 4 channel relay shield (HCARDU0102) which conveniently and safely allows an Arduino to interface to the outside world via a set of relays. The shield will plug into an Arduino with standard headers and screw terminals for the relay contact means that no soldering is required. The relays can be individually controlled via 4 digital pins on your Arduino. An on board 5V regulator means that...

This data logger shield provides an Arduino Uno, Leonardo, or Mega with the ability to log sensor data to an SD card with the minimum of set-up. The shield provides several useful features:

This adapter board shield (HCARDU0084) is intended to be used with our 2.4" TFT touch screen module (HCARDU0083) which is also available for purchase via our website. This shield allows the TFT screen to be easily interfaced with an Arduino boards such as an Uno or Leonardo. It also includes level shifters to provide correct 3.3V voltage level inte...

This Screw Shield is a terminal expansion board which can be stacked directly on the female pins of an Arduino uno/mega/leonardo and allows easy connection for many sensor parts with no soldering required. This shield set (2 Boards) is fully Arduino compatible. The Arduino compatible Uno in the image is not included.

This Arduino Uno and Leonardo compatible multifunction experimenter shield (HCARDU0085) has a large range of features which makes it ideal for beginners who just want to experiment and learn, or just as a general purpose shield for more advanced uses. Besides the feature rich range of components fitted to the shield, there are also a range of expansion...

This adapter board shield (HCARDU0098) is intended to be used with our 3.2" TFT touch screen module (HCARDU0097) which is also available for purchase via our website. This shield allows the TFT screen to be easily interfaced with an Arduino Mega. It also...

This shield is compatible with most types of Arduino boards that support the standard header layout including Uno, Leonardo, and Mega. It provides a convenient way to connect various sensor modules, servo's, or I2C LCD displays without the need for soldering.

Please note: I2C interface compatible with Uno only. When connecting multiple servos please check power requirements of each servo.

This shield (HCARDU0086) is designed to allow you to control a CNC router or milling machine from an Arduino board. It contains 4 driver sockets which allows compatible Pololu A4988 driver modules to be inserted (see HCMODU0068 on our website) providing the ability to drive 3 stepper motor axis (X,Y, & Z) plus an optional 4th ...

The Hoby Components high power motor drive shield (MonsterMoto compatible) is based on the Sparkfun reference design and uses two ST Microlectronics VNH2SP30-E full bridge high power motor drivers to independently control the speed and direction of two DC motors. The pinout of the shield means that each motor can be di...

This Ethernet Shield is based on the Wiznet W5100 Ethernet Chip and gives you an easy way to get your Arduino online.

This shield (HCARDU0014) is designed for 5V Arduino boards that use the standard Arduino header layout such as the Uno, Leonardo, Mega, etc. It is compatible with the standard Arduino LiquidCrystal library which is built into the Arduino development environment (see our example sketches for correct configuration). The shield includes a 16 character by 2 line LCD display with exceptionally...
