Libre Computer ROC-RK3399-PC USB Type-C Power Delivery Adapter Testing

USB Type-C Power Delivery is a series of complex specifications governing how data and power roles are negotiated. There are many devices on the market advertising USB PD compliance but do not strictly adhere to the standard. These deviations to cut cost or complexity result in incompatibilities. SBCs are not battery backed and are especially sensitive to the incompatibilities since the whole system may power down if the power source is not compliant.
