TFT LCD driver with DPI interface dedicated to Raspberry Pi. It allows you to operate resistive touch panels. Adafruit 2453

This compact expansion board plugs directly into the GPIO header on a Raspberry Pi B+, A+, or Pi 2 and provides an easy and low-cost solution for driving a pair of small brushed DC motors. Pololu 2753

PiFace Relay Motor Control Extra (Board) for Raspberry Pi

Adafruit 2324

Adafruit 16-Channel PWM / Servo HAT for Raspberry Pi - Mini Kit (Adafruit 2327)

2.8" display with 320x240 16-bit color pixels and a capacitive touch overlay fits perfectly onto the Raspberry Pi 3/2/A+/B+. The display and touchscreen uses the hardware I2C Pins (SDA & SCL), SPI pins (SCK, MOSI, MISO, CE0) as well as GPIO #25 and #24. Adafruit 2423

Adapter enabling easy and quick connection of expansion modules compatible with the Modular DuoNect to selected Raspberry Pi platforms (with a 40-pin connector). MOD 80

Atmel ATmega32U4 microcontroller comes preloaded with an Arduino-compatible bootloader, and the board includes dual motor drivers that can deliver 1.7 A per channel to two brushed DC motors. Pololu 3119

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 real time clock (RTC) PCF8523 dedicated for minicomputers Raspberry Pi. It communicates via the I2C interface. Adafruit 3386

Module with e-Paper display, 5.83" diagonal and 648x480 px resolution. Communication via SPI interface. Waveshare 5.83inch e-Paper HAT (B)

Controller module for building an arcade game dedicated to Raspberry Pi. Connectors placed on the board allow you to connect 6 momentary buttons, a joystick and a loudspeaker. Adafruit 3422

DEV-14317

This add-on board makes it easy to control two high-power DC motors with a Raspberry Pi. Its twin discrete MOSFET H-bridges support a wide 6.5 V to 30 Voperating range and are efficient enough to deliver a continuous 18 A without a heat sink. The drivers offer basic current limiting functionality, and they accept ultrasonic PWM frequencies for quieter operation.
