High-End Setup (EasyBox)
The 3DPrinterOS EasyBox is our official pre-configured solution. Every component is selected for industrial-grade durability and maximum reliability.
Key highlights:
Kingston SDCIT2 industrial microSD with power failure protection, strong ECC engine, bad block management, and extremely high endurance (industrial-grade, significantly exceeding consumer cards)
Logitech C920 HD Pro with glass lens, autofocus, stereo mic, and 1080p/30fps
Multicomp PRO power supply with interchangeable AC heads (UK, Euro, USA, AUS), UL/CE/FCC certified, 50K hour MTBF
Digitus Professional CAT 6 ethernet with gold-plated RJ45 connectors

Tom's Hardware ranks it among the best Raspberry Pi microSD cards, noting it promises up to 25x greater longevity than typical consumer cards. Strong all-around performer in Pi 4 benchmarks.
Power Supply: Official Raspberry Pi USB-C Power Supply (5.1V / 3A)
Designed and tested specifically for the Raspberry Pi 4
5.1V output, 3A max
Available in region-specific plug variants (US, UK, EU, AU)
Current price: ~$8-10
The official PSU is the safest choice for voltage stability and avoids the low-voltage warning icon
Ethernet Cable: Any reputable brand CAT 6 patch cable (1m)
CAT 6 supports up to 10Gbps over shorter distances and 1Gbps over standard cable lengths (far exceeding the Pi 4's Gigabit Ethernet)
Recommended brands: Monoprice, Cable Matters, AmazonBasics, StarTech
Current price: ~$3-5
Case: Any well-reviewed Raspberry Pi 4 case
CanaKit Premium Case (~$8), Argon ONE V2 (~$25 with passive cooling), or Flirc (~$16 with passive heatsink)
Choose based on whether active or passive cooling is needed for your environment
Budget Setup
The most cost-effective configuration that still uses quality, well-reviewed components from trusted brands. Suitable for labs, classrooms, and pilot deployments where cost is a primary concern.
Board: Raspberry Pi 4 Model B - 1GB RAM
Same processor as the 2GB variant (Cortex-A72 @ 1.5GHz)
1GB is sufficient for running the 3DPrinterOS client
Typical price: ~$35-50 depending on availability and region
Note: 1GB boards have limited and inconsistent availability and may be difficult to source depending on region
Camera: Logitech C270 HD
720p HD at 30fps
Fixed focus, plastic lens
Built-in mono microphone with noise reduction
55-degree diagonal field of view
1.5m USB-A cable
Plug and play on Raspberry Pi OS (UVC compatible)
Current price: ~$18-22
One of the most popular webcams ever made, with tens of thousands of reviews. Works reliably with Raspberry Pi out of the box. The 720p resolution is lower than the C920 and Brio 100, but is perfectly adequate for print monitoring. Reviewers note the C270 is lightweight and durable, with surprisingly good image quality for its price in decent lighting.
MicroSD: SanDisk Ultra 32GB (A1 rated)
Speed: Up to 120MB/s read
Performance: Class 10, UHS-I, U1, A1
Operating temperature: -25C to 85C
Current price: ~$7-10
The A1 rating ensures adequate random read/write performance for running an OS, which is critical for Raspberry Pi use. Tom's Hardware and Raspberry Pi community forums consistently recommend SanDisk Ultra A1 cards as a reliable, affordable option. Multiple forum users report running these cards for years without failure. Avoid cards without the A1 rating for OS boot use.
Power Supply: CanaKit 3.5A USB-C Power Supply
5V/3.5A output (slightly higher amperage than the official PSU)
UL Listed
18 AWG cable, 5-foot length
Built-in noise filter for power stability
Current price: ~$10
CanaKit is one of the largest Raspberry Pi accessory vendors and this PSU is widely used in their starter kits. Well-reviewed on Amazon with thousands of ratings.
Ethernet Cable: Any reputable brand CAT 5e patch cable (1m)
CAT 5e supports up to 1Gbps, which fully covers the Pi 4's Gigabit Ethernet
Recommended brands: Monoprice, Cable Matters, AmazonBasics
Current price: ~$2-4

CanaKit basic case (~$5-8) or GeeekPi case with heatsinks (~$8)
Ensure the case allows access to all ports and has ventilation
Important Notes
Wi-Fi vs Ethernet: We strongly recommend using a wired Ethernet connection for the most stable and reliable connection to 3DPrinterOS. Wi-Fi is supported but may introduce latency or connectivity drops, especially in environments with many wireless devices.
MicroSD card quality matters: A failing or low-quality microSD card is the most common cause of Raspberry Pi reliability issues. Always purchase from authorized retailers to avoid counterfeit cards. Stick to reputable brands: Samsung, SanDisk, Kingston.
Power supply quality matters: Undervoltage is the second most common issue. Always use a power supply rated for at least 3A at 5.1V. Generic phone chargers are NOT suitable. The low-voltage lightning bolt icon on screen indicates insufficient power delivery.
USB camera compatibility: The cameras listed above are verified to work with the Raspberry Pi and 3DPrinterOS. Other USB webcams may also work, but compatibility is not guaranteed. Avoid cameras that draw excessive power from the USB port, as this can cause instability. See our Camera Troubleshooting Guide.
USB bandwidth: Avoid connecting multiple high-bandwidth USB devices (such as webcams) through a single USB hub, as this may impact performance. For multi-printer setups, refer to our guide on How many 3D printers can be connected to one device.
Operating temperature: The Raspberry Pi 4 is rated for 0-50C ambient temperature. In enclosed or warm environments, a case with active cooling (fan) is recommended to prevent thermal throttling.
