Tuya Zigbee/BLE multi-mode wireless gateway

It integrates a step-down module and can be plugged into any socket and it will work. For detailed instructions, please refer to the original project. I am very lazy and can only modify the schematic diagram briefly. Those who have this gateway module can dismantle the internal organs and modify it according to their own abilities and needs. , pay attention to the safety of electricity when debugging. The PCB file is the second version. The switch circuit of the power indicator light is added. The first version is to press the down button to view the power indicator light. The added part has not been verified and may not be usable. It will not affect For the original function, the indicator light uses a side-mounted patch or the LED is stood up and soldered. The upper button is connected to the network, and the lower button power indicator circuit does not need to be soldered. It is useless. I just don't want that position to be empty. . Choose one of the two positions of the LED indicator for welding. The ability is limited. It’s my first time to use Lichuang EDA to draw a PCB. Let’s just give it a try.
