Although some share a similar form factor to the Raspberry Pi, and many also copy the GPIO pinouts, in many cases, these other computers offer features unavailable in a traditional Raspberry Pi.

The new Raspberry Pi 500 computer keyboard now includes the same features and performance upgrades of the Raspberry Pi 5 microcomputer, including improved dual display support.

With Opto-pi, there is not an electrical connection between the Raspberry Pi and connected loads (motors, relay coils, etc.) or input signals. Opto-pi uses light to isolate the 8 digital GPIO pins.
