I finally got my first Raspberry Pi and I plan to use it to run a node for a crypto project that I am following. At the same time, my dear friend 
Basic information about the device
I bought the latest Raspberry Pi 4 Model B. There are 1GB, 2GB and 4GB (in terms of RAM) variations for this device, and the one I bought is the mid-tier one at 2GB RAM (immediate screenshot below).
I got the device from Cytron, they are the official distributor for Raspberry Pi in Singapore. The 2GB version costs S$70 now, and you get free shipping when you buy above S$100 worth of products. The prices for the different variations as below.
I forgot to take a picture of the device before I assemble it into my case, so the below picture is courtesy of Cytron. This is exactly how it looks like when I took it out from the box.

The Raspberry Pi 4 is a reasonably powerful and versatile device. Here are the technical specifications of the Raspberry Pi 4.
Source
- Broadcom BCM2711, Quad core Cortex-A72 (ARM v8) 64-bit SoC @ 1.5GHz
- 1GB, 2GB or 4GB LPDDR4-3200 SDRAM (depending on model)
- 2.4 GHz and 5.0 GHz IEEE 802.11ac wireless, Bluetooth 5.0, BLE
- Gigabit Ethernet
- 2 USB 3.0 ports; 2 USB 2.0 ports.
- Raspberry Pi standard 40 pin GPIO header (fully backwards compatible with previous boards)
- 2 × micro-HDMI ports (up to 4kp60 supported)
- 2-lane MIPI DSI display port
- 2-lane MIPI CSI camera port
- 4-pole stereo audio and composite video port
- H.265 (4kp60 decode), H264 (1080p60 decode, 1080p30 encode)
- OpenGL ES 3.0 graphics
- Micro-SD card slot for loading operating system and data storage
- 5V DC via USB-C connector (minimum 3A*)
- 5V DC via GPIO header (minimum 3A*)
Assemble the device
There are a few important components that you need in order to run the Raspbian OS and get your Raspberry Pi working. At the very least, you need a 5V/3A power connector (top left of picture) and a MicroSD card (bottom right of picture). You also need a micro-HDMI cable to connect to your monitor, the standard HDMI cable will not work. Last but not least, you also need a set of keyboard and mouse :)
When buying a MicroSD card, make sure you read the official recommendations first. General rule of thumb is to at least get a 64GB class-10 MicroSD card.
As you can see in the picture, I also bought a case and a case fan. These are not mandatory but I think they are nice to have. They do not cost a lot if you buy it from sites like Lazada or Shopee. Depending on which case you buy, the assembly will be different. Hence, I am skipping the case assembly part and here is how my device looks like after I put it into the case.
Flashing Raspbian to MicroSD Card
The next thing you need to do is to "install" the Raspbian Operating System (OS) into your MicroSD card. The correct term to use here is to "flash" the OS, but "install" probably sound more beginner-friendly :)
To "flash" the OS, you need to use another computer, it can be a Mac or Windows PC. You also need to connect your MicroSD card. Some computers come with a MicroSD card slot, if yours does not have, you can purchase an adaptor which looks something like this,

This basically converts you MicroSD card to USB and you will be able to access it via you computer through a USB port. Next, you need to download Raspbian OS which is available at the official Raspberry Pi site.
Again there are a few variations here. I chose the one with a GUI desktop for ease of setup. There is another version with a set of recommended pre-installed software. I think the software are not necessary for my purpose but feel free to choose that if you like to use those software, the rest of this guide will still be the same.
While you are downloading the Raspbian OS, you can go ahead and also download the "flash" utility. BalenaEtcher is the recommended utility to flash the OS.
After you downloaded BalenaEtcher, install it. I am using a Windows PC and the screenshots below are applicable for Windows.
Once installed, open the application. The utility should auto-detect your SD card if you have it connected to your PC. You then have to select a image file to be flashed into you SD card. By now, your Raspbian OS download should be done (it is a zip file), and you can go ahead and select that for the image (you do not need to unzip the file).
After that, click "Flash!" and it will magically start flashing you SD card with the OS. It will take about 10 minutes.
When you see the "Flash Complete" page, you are done!
Setting up Raspbian
Before you power up your Raspberry Pi, put in the SD card, which you just flashed with Raspbian OS, into the MicroSD card slot. The slot is located opposite of the USB ports. After that, plug in the power supply and connect the Micro-HDMI with your monitor. Power the device up and watch Raspbian OS loads...
When it boots up, you will be greeted by the following welcome screen. Click next.
Like any devices, it is important to change the default password. It is basic security hygiene and I recommend you to do so now, otherwise you will simply forget later :)
After stepping through a few screens, including connecting to your WiFi, it will prompt you to perform an update, of which you it will fail. But fret not, I will teach you how to update it later. For now, just follow through the step and perform a restart when prompted.
When your Raspbian OS boots up again, you can perform update manually. Fire up a terminal console (4th icon from top left corner of the screen). Then enter the following command:
- sudo apt-get update
This will trigger the updates to be downloaded as shown below.
Once done, run the second command to install them:
- sudo apt-get upgrade
After the updates are installed, you are done. The OS is shipped with a Chromium browser and with that you will be able to browse Steem! There is nothing else you should be doing first :p
So here is me browsing Steempeak
Oh and by the way, this post is written and posted from my Raspberry Pi too!
Some afterthoughts
While there are many things you can do with your Raspberry Pi, do not expect your browsing experience to be blazing fast. Remember that the device costs under S$120 with everything in. You can search online on what else you can do with your Raspberry Pi, have fun and feel free to drop me any questions.
If you also have your own Raspberry Pi, do share with me what you are using it for.
