Wondering whether to buy a Raspberry Pi or a mini PC? For everyday desktop computing, most mini PCs will outperform a Pi. But the two machines are built for different jobs, and there are several things a Raspberry Pi can do that a mini PC simply cannot match.

Raspberry Pi vs Mini PC: GPIO Pins Unlock Real-World Projects
The most obvious difference is physical. Most mini PCs are closed boxes with the hardware hidden inside. A Raspberry Pi, by contrast, is a bare single-board computer with clearly visible GPIO (general-purpose input/output) pins.
Those pins let you connect physical components that the computer can then control, from simple buttons and LEDs to complicated sensors or relay modules. A mini PC offers no equivalent: you can plug devices into USB ports or add a separate microcontroller, but it is not as simple as wiring components straight to pins.
That direct hardware access is why the Pi remains the go-to board for makers, students and smart-home tinkerers, even as mini PCs get faster and cheaper.
USB Gadget Mode: When the Pi Becomes the Peripheral
The USB ports on a typical mini PC work as hosts for peripherals such as keyboards or storage drives. Some Raspberry Pi models, including the Raspberry Pi Zero, also support USB gadget mode, which flips that relationship around.
In gadget mode, the Pi itself acts like a peripheral, so it can appear to another computer as a device rather than as a host. That opens up project ideas a sealed mini PC cannot easily copy, from custom USB gadgets to clever ways of connecting two machines together.
The bottom line is simple: if you want a small desktop computer, buy a mini PC. If you want a cheap, open board to build things with, the Raspberry Pi still plays a game of its own.
