1.Comes with PD power supply protocol, suitable for 5, and compatible with for NANO, K210, STM32 and other development boards. 2.Supports 6-24V voltage input and 5V/5A voltage output. 3.Can be stacked with for 5 through screw copper posts. 4.Onboard three input interfaces: KF301-2P pitch 5.08mm, XH2.54-2Pin, DC5.5x2.5. 5.Onboard three output interfaces: Type-C, PH2.0-2P, DC5.5x2.1, 6Pin. This is power supply expansion board tailor-made for 5. Integrating multiple types of input and output ports and efficient voltage stabilization technology, it can that the input power is stably adjusted to the 5V/5A output, perfectly meeting the power needs of the for 5. Effectively eliminating potential low-voltage operation risks, and avoiding USB interface current limitation. have designed fixed holes for this expansion board, which can be stacked directly on the for 5. The overall height is suitable for smart cars, robots and other mobile platform projects.
