Doodle Zigbee/BLE multi-mode wireless gateway

Integrated step-down module, just find a socket plug in to work, detailed description see the original project, I am very lazy, the schematic diagram is only simple modification, there is this gateway module can be based on their own ability and needs to dismantle the internal organs to change, pay attention to electrical safety during debugging, PCB file for the second version, add the power indicator switch circuit, the first version is to jog the next key to view the power indicator, the increase part is not verified, may not be usable, does not affect the original function, the indicator light uses a side patch or the LED is erected and welded, The upper key is used to distribute the network, and the lower key power indicator circuit is not welded, which is useless, but I don't want that position to be empty. LED indicator two positions two choose one soldering, limited capacity, the first time to use LC EDA to draw PCB, will look at it.
