Single-board mini computers from the Raspberry Pi series have gained recognition around the world. They are used by both home-type tinkerers and professional designers of programmable electronic devices. In 2019, the latest model appeared on sale - the Raspberry Pi 4B. Compared to previous models, Pi 4B has been equipped with an even more efficient quad-core processor Broadcom BCM2711 clocked at 1,5 GHz of frequency and for the first time, it consists two Micro HDMI outputs for external monitors instead of a single standard A-type HDMI connector. You can use the Raspberry Pi 4B in the same way as a standard PC for internet browsing and office work, as well as a driver for physical devices with electronic and mechanical systems, thanks to the versatile 40-pin GPIO connector. By using the GPIO connector in Raspberry Pi, you can easily create a home automation management centre, electrical drive controller, audiophile D-class amplifier, retro-style gaming machine, remote control apparatus for unmanned vehicles and much more! Sounds marvellous, isn't it? And it's still real to come true - just use the Raspberry Pi HAT hardware extension boards that are GPIO-compatible with Raspberry Pi 4B!

An interesting offer for music and electronics enthusiasts
Using the Pimoroni Piano HAT overlay, you can turn the Raspberry Pi 4B into a simple music synthesizer with keyboard and buttons. According to the standards in the hardware design of synthesizers and drum machines since the 1980s, this overlay supports MIDI protocol (Musical Instruments Digital Interface). The keyboard contains a single octave with a C1-C2 tonal range (13 notes). These are capacitive touch keys. In addition, the user has at his disposal buttons for changing the tonal range (Octave Up / Octave Down) and a button for selecting sound presets stored in memory. The Piano HAT overlay is equipped with a GPIO connector that is compatible with the Raspberry Pi 4B minicomputer hardware. A practical feature of the overlay is built-in LEDs that perform an educational function. All you have to do is follow which of the LEDs that are linked with keys are lights up to learn to play simple songs from scratch. The program implementing this function was written in Python and is pre-loaded into memory in the Piano HAT module. The alternative,,non-musical” project, which you can create by using this board is a whac-a-mole game.
A simple way to control electrical circuits powered by mains voltage
Also, SparkFun Electronics has prepared interesting hardware extensions for Raspberry Pi. The RELAYplate module contains seven Single-Pole Single-Throw Normally Opened electromechanical relays. With this overlay, you can control the circuits powered by a voltage of 120VAC or 30VDC. The overlay allows you to switch-on and switch-off the power supply of electric motors, pumps, fans, lighting, heaters and other electrical devices. The kit includes a protective cover to prevent accidental electric shock due to contact with high voltage circuits. At the same time, you can connect eight such modules together, which gives you the ability to control up to 56 circuits in parallel, independently of each other. The board is equipped with LEDs that indicate the state of contacts of individual relays. The RelayPLATE overlay is controlled by a 40-pin GPIO connector, the pin layout of which is compatible with most models of the Raspberry Pi minicomputer, including Pi 4B.
