Orange Pi board schematic for the Allwinner A20-based model, revision 1.1, in a 354 KB PDF. The document details the power supply circuitry, A20 SoC wiring, memory, network and USB interfaces, and expansion headers. It supports fault-finding such as measuring each regulator output, tracing a short to a specific capacitor, or confirming GPIO assignments for add-on hardware. Any PDF viewer opens it. Match the revision on the PCB to 1.1 before trusting the component values and routing shown.
