If you’ve got a Raspberry Pi and an OLED display, you can use them to create your own retro handheld games console or mini laptop. In this tutorial we’ll show you how to install the pHAT DAC and its software onto your Raspberry Pi, then attach the OLED display so it will work with the board.
There are many tiny OLED displays you can use with a Raspberry Pi. One of the most popular is the 128×32 I2C model from Adafruit, which costs just over £10.
The Raspberry Pi GPIO pins are located on the left-hand side of your board and numbered in order from 1 to 40. If you’re using an older model of Pi, you might find that some or all of these pins are occupied by built-in components such as an Ethernet port and USB host controller, so check which ones before you start connecting your own hardware.
The GPIO port is connected to two other buses: SPI (Serial Peripheral Interface) bus for communicating with microcontroller chips like those found inside SD cards; and I2C (Inter-Integrated Circuit) bus for connecting low-speed peripherals such as sensors or motors without needing extra wires between them all over again–they’re automatically powered up when data signals pass through them thanks to cleverly designed circuitry inside each chip used here.
You could connect it directly to the Pi’s GPIO port but this would require lots of wires so a pHAT DAC is a much better option. This is an add-on board for the Raspberry Pi that offers a stereo 3W Class-D amplifier and a stereo analogue to digital converter (ADC). It also comes with a ribbon cable that allows you to attach an OLED display on top of the board.
The Raspberry Pi Zero W features a 1GHz CPU, 512MB RAM and mini oled display HDMI port. It’s great for starting out with computer vision, home automation or playing classic games like Doom or Wolfenstein 3D on your TV.The pHAT DAC is an audio-visual add-on board which connects using the 40 pin GPIO header on Raspberry Pi boards that has been designed specifically for use with DAC HATs like Hifiberry Digi+ Pro (Amp).
Attach an OLED display to your Raspberry Pi and make your own retro handheld games console or mini laptop.
The Raspberry Pi is a great way to build your own electronics projects, whether you want to make your own retro handheld games console or mini laptop. The OLED display provides clear, crisp text output for all kinds of projects, and the pHAT DAC gives you access to audio via Bluetooth or USB.
The Raspberry Pi Zero W is an excellent choice for this project because it has built-in Wi-Fi and Bluetooth support, meaning that there’s no extra setup required except plugging in the power supply (and maybe attaching an HDMI cable).
This is a great project for beginners looking to become more familiar with electronics and how they work. You can use it as an educational resource in schools, or simply have fun learning how to create your own retro handheld games console or mini laptop.
