Find Orange Pi pinouts instantly with this free Orange Pi Pinout Reference. View GPIO layouts, power pins, communication interfaces, expansion headers, and pin configurations for Orange Pi single-board computers.
Configuring Orange Pi UART Busses
Establish serial debugging consoles by targeting the dedicated TX and RX pins with a 3.3V USB-to-UART bridge.
Safe PoE Setup
Before applying PoE inject voltages, confirm that on-board bridge resistors match your project power requirements.
Driving 3.3V Logic Safely
Never exceed 3.3V on standard GPIO lines. Use active step-down level converters when bridging 5V sensor outputs.
Checking Pin States with wiringOP
Run the console terminal query gpio readall to view translated Pin registers in real time.

Orange Pi developmental modules operate on Allwinner and Mediatek SoC architectures. Because these modern silicon dies feature sub-micron processes, they rely on clean, stabilized 3.3V CMOS logic signaling. Applying direct 5V input lines to these delicate ports will compromise internal chip junctions and lead to complete processor failure.
This reference index consolidates pin configurations, expansion header maps, and line assignments for the Orange Pi family.
Finding accurate pinout layouts is crucial for embedded designers, system architects, IoT engineers, and DIY hobbyists. This directory documents active signal paths to help prevent wiring errors, serial protocol failures, and board damage.
Always verify pinout configurations with a digital multimeter before powering up custom circuits or shield adapters.
No, the logic pins operate strictly at a 3.3V threshold. Exposing any GPIO, SPI, or UART pins to a 5V logic source without a level shifter can cause immediate hardware failure.
Most Orange Pi boards configure their main UART debug terminal (typically UART0 or UART2) to a baud rate of 115200 by default.
The Zero uses on-board zero-ohm resistors (R29 and R358) to route passive DC power from Ethernet pairs 4/5 and 7/8 directly to the main 5V and Ground lines.
High-density boards like the RK3399 share physical SoC traces between certain GPIO pin groups and the CSI camera connector, disabling these pins when the camera is active.
