Build Your Own Raspberry Pi Cyberdeck: A Portable DIY Terminal
A cyberdeck is a portable, self-built computer terminal — a small screen, a compact keyboard, and a single-board computer like a Raspberry Pi, wired together into a case you carry rather than a machine that sits on a desk. It runs a full Linux operating system, not embedded firmware, so the "build" is really two builds in one: an enclosure and wiring job on the hardware side, and a software setup on the Pi itself once it boots. Builders take this route to get a retro-styled, purpose-built terminal for coding, scripting, or tinkering on the move, without carrying a full laptop.
What parts does a Raspberry Pi cyberdeck need?
At minimum, a cyberdeck needs a Raspberry Pi board to act as the computer, a small display, a keyboard for text input, a microSD card to hold the operating system, a battery for portable power, and a case to hold everything together. Most builders also add some way to get wireless networking if the chosen Pi board doesn't already have Wi-Fi built in. None of this is embedded firmware in the sensor-project sense — the Pi boots ordinary Linux, and anything you "program" is a script or application that runs on top of that OS.
What display and keyboard work best for a small cyberdeck?
Small SPI or HDMI touchscreen LCDs in the 3.5-to-5-inch range are the common choice for cyberdecks, since anything larger stops being pocketable and anything smaller becomes hard to read. For the keyboard, this is the one part that is easy to get wrong when speccing a build from parts alone: a general electronics catalog is built around modules and components, not full keyboard peripherals, so it is worth checking carefully that whatever fills the "keyboard" slot in a build tray is an actual keyboard and not a stand-in like a wireless adapter that merely lets you pair one. A compact mechanical or membrane keyboard, wired or paired over Bluetooth, is what you actually want typing on.
Do you need to 3D print a case?
No. A 3D-printed shell is the most common way cyberdeck builders get the exact retro-terminal look, but it is not a requirement. A basic foam or plastic electronics enclosure will hold the board, screen, and battery together and keep the wiring protected, which is enough to have a working, carry-around unit. 3D printing becomes worthwhile once you want a specific form factor — an angled screen, a built-in keyboard well, a handle — that a generic box can't give you.
What can you actually do with a cyberdeck?
A working cyberdeck gives you a self-contained Linux terminal for SSH-ing into other machines, writing and running code, reading documentation offline, or running lightweight scripts and utilities, all without opening a laptop. Because it's just a Raspberry Pi under the retro exterior, it can do anything a headless or small-screen Linux box can do — the appeal is the form factor and the fact that you built it yourself, not a capability a laptop lacks.
Watch it built live
We typed this into Compoden's storefront assistant, Soldr:
"I want to build a portable cyberdeck using a Raspberry Pi, a small screen, and a compact keyboard"
Soldr checked its catalog and assembled a build in 2.5 seconds, logged as 2 build steps covering 6 parts decided and an 8-of-8 in-stock catalog check (7 parts made it into the final tray). Here is what it said back, quoted directly from that reply:
"This build creates a portable cyberdeck, which is a small, self-contained computer. It uses a Raspberry Pi Zero (Revision 1.3) as the main computer, a small screen for display, and a wireless connection for input, all powered by a battery. This lets you have a basic computer that you can carry with you."
On the screen it picked:
"The 3.5 inch TFT LCD Resistive Touchscreen Display Module for Raspberry Pi (SPI, 480x320) is your screen. It's a small display with 480x320 pixels… It's a resistive touchscreen, so you can interact with it by pressing on the screen… This screen is a good fit because it's small and has touch input, perfect for a portable device."
On the part filling the keyboard slot, the reply itself is honest about what the part actually does, even though the build log's own slot label calls it "Compact Keyboard":
"For wireless connections, you have the WiFi Bluetooth USB Mini Wireless Dongle. This small device adds Wi-Fi and Bluetooth capabilities. It connects to the Raspberry Pi using a USB port… This dongle is needed because it provides the wireless communication for your keyboard and internet access."
In other words: this part is a wireless adapter that lets you pair a keyboard, not a keyboard itself — the storefront's own PWA build assistant flagged the same gap independently later in this article's capture, reporting "no match found" for an actual keyboard product. We've kept that distinction in the parts table below rather than presenting the dongle as a keyboard.
Soldr also explained the rest of the tray in the same reply — the microSD card ("The 8GB size is enough for a basic Linux system and some applications"), the battery ("This battery is chosen to make your cyberdeck truly portable, allowing it to run without being plugged into a wall"), and its board choice ("The Raspberry Pi Zero (Revision 1.3) was chosen because it is the lowest-cost board that meets the requirement for a compact, Linux-capable computer with built-in wireless features"). Here is the build tray it produced, screenshotted directly from the live storefront:
Watch the startup script get generated
Since a cyberdeck runs a full Linux OS rather than embedded firmware, we asked Compoden's PWA build assistant for a startup script instead of sensor firmware:
"I'm building a Raspberry Pi cyberdeck with a small screen and keyboard. Write a simple Python startup script that shows a welcome message and system info (CPU temp, battery/power status if possible)."
The assistant handled the framing cleanly rather than pushing back toward an embedded-firmware answer — its Firmware tab labeled the output "PYTHON" and noted directly under the compile controls: "Python runs straight on the board — no compile step." The build log for this second session independently re-specced its own parts list (6 parts, 7-of-8 matched) and, on its own, hit the same gap the storefront reply had already flagged in prose: the keyboard slot came back "no match found," and it was listed separately under the tray's "still needed" parts. The generated script itself:
"Here's a Python script for your Raspberry Pi cyberdeck that displays a welcome message and system information like CPU temperature and basic power status. It's designed to run on startup and output to the console, which would be visible on your 5-inch HDMI display. For battery status, a dedicated power management IC (PMIC) or UPS HAT would be needed to provide accurate readings; this script will check for a common power status file if available, otherwise, it will indicate 'N/A'."
The code appeared all at once in the Firmware tab rather than streaming in line by line. It's plain Python using os, time, and subprocess, and it reads CPU temperature with the Pi's own vcgencmd measure_temp command, falling back to reading /sys/class/thermal/thermal_zone0/temp directly on boards or systems where that tool isn't available:
def get_cpu_temperature():
"""Reads the CPU temperature from the system."""
try:
temp_output = subprocess.check_output(["vcgencmd", "measure_temp"]).decode("utf-8")
return temp_output.replace("temp=", "").strip()
except (subprocess.CalledProcessError, FileNotFoundError):
# Fallback for older Pis or different Linux systems
with open("/sys/class/thermal/thermal_zone0/temp", "r") as f:The assistant was also upfront about what it couldn't verify, since this session's tray had no single confirmed board carded against it for a pin-accurate compile:
"Heads up — this code has not been checked against a board. Your build has parts in it, but no board I can compile for — so I could not verify the pins. If you are using a board you already own, tell me exactly which one and I will re-generate it properly wired for that board."
It flagged power budget honestly too, rather than implying a small battery could run a bigger board indefinitely:
"Note: power budget: this build can draw up to ~3000 mA (Raspberry Pi 4 Model B 1GB ~3000 mA) — more than a small battery sustains for long. For real off-mains use you'd want a large 18650 pack (and deep-sleep in the firmware), or mains. Flagging it honestly rather than implying a small cell would run it."
Who this build is for
This suits anyone who wants a small, retro-styled Linux terminal to carry around for coding, SSH, or tinkering, and who doesn't mind a weekend spent on wiring, case assembly, and Linux setup rather than a purely plug-and-play kit. It's beginner-friendly on the electronics side — the storefront rated it "Beginner (every part plugs in, no soldering)" and suitable for roughly age 10 and up — but you'll still need to source and pair your own keyboard, since none of the parts carded by either assistant in this capture is an actual keyboard.

The storefront also lists the Raspberry Pi 4 Model B (1GB) and Raspberry Pi 5 Model B (8GB) as alternates to the Zero used in this build, and 16GB, 32GB, and branded 32GB microSD cards as alternates to the 8GB card — useful if you want a faster board with more RAM or more room for a fuller Linux install. Compoden does not currently list a dedicated compact keyboard in this build's tray, and the Raspberry Pi Zero has no built-in microSD slot interface of its own beyond the card edge connector, so double-check card compatibility for your specific Zero revision before assembling.
Built and backed by Compoden: every part above ships from Compoden's own catalog with stock and pricing pulled live from the storefront at the time this article was written, and every purchase is covered by Compoden's standard shipping and return terms.
Frequently asked questions
What parts does a Raspberry Pi cyberdeck need?
A Raspberry Pi board, a small display, a keyboard, a microSD card for the operating system, a battery for portable power, and a case. Most builders also add a wireless adapter if their chosen Pi board doesn't already have built-in Wi-Fi.
What display and keyboard work best for a small cyberdeck?
Small SPI or HDMI touchscreens in the 3.5-to-5-inch range are the common cyberdeck display choice. For the keyboard, make sure the part actually is a keyboard — a general electronics catalog can surface a wireless adapter or dongle in that role instead of a real keyboard, and you'll need to source and pair the keyboard itself separately.
Do you need to 3D print a case?
No. A 3D-printed shell is the common way builders get a specific retro-terminal look, but a basic foam or plastic electronics enclosure is enough to hold the board, screen, and battery together for a working build.
What can you actually do with a cyberdeck?
Anything a small, self-contained Linux box can do — SSH into other machines, write and run code, read documentation offline, or run lightweight scripts, all from a portable terminal you built yourself.
