Compatibility
This Raspberry Pi 4 works with all standard Raspberry Pi OS images, Ubuntu, and other ARM64 OSes. It is compatible with most modern Pi HATs and pHATs, as well as Arduino shields via bridging boards. GPIO operates at 3.3V logic; pair with a 5V power supply (official USB-C adapter recommended) for stable operation.
Wiring Notes
When connecting external devices, ensure correct voltage levels to avoid damaging the 3.3V pins. I2C and SPI interfaces require enabling in raspi-config before use. The board can source limited current from GPIO; for motors or high-current devices, use an external driver circuit.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino?
Direct GPIO interfacing with Arduino is possible via level shifters (3.3V to 5V). For full integration, consider using a Raspberry Pi as an Arduino bridge with Firmata.
Does this include a power supply?
No, the power adapter is sold separately. We recommend the official 5V/3A USB-C power supply for reliable performance.
Can I use this without a keyboard and monitor?
Yes, you can set up a headless connection via SSH over Wi-Fi by enabling it in the OS configuration before first boot.
📦 Free Setup Handoff Document Included
