This module allows you to integrate a microcontroller into a Bluetooth network.

Most Arduino® boards have limited onboard memory storage. The WPI304B MicroSD card logging shield allows expanding the storage to up to 2 GB.

The VMA317 (1838) is a miniaturized infrared receiver for remote control and other applications requiring improved ambient light rejection.

This module based on Nordic nRF24L01, highly integrated, ultra low power (ULP) 2Mbps RF transceiver for the 2.4GHz ISM (Industrial, Scientific and Medical) band. Nordic nRF24L01+ integrates a complete 2.4GHz RF transceiver, RF synthesizer, and baseband logic including the Enhanced ShockBurst™ hardware protocol accelerator supporting a high-speed SPI interface for the application controller.

This 3,5" Resistive Touchscreen Display for the Raspberry Pi is perfect for creating portable and embedded projects where a keyboard and mouse would be in the way.

This RFID module allows to both read and write MiFare-type RFID cards.

This module allows full control of two DC motors or one stepper motor.

A rotary encoder is an input device that indicates the rotating direction and how much the knob has been rotated. A rotary encoder is useful for for stepper and servo motor control.

The Velleman WPI440 can be used this module to program VMA439 through USB. Converts USB to TTL.

A keypad is a simple method of entering user input into your project.
