Package Includes:
1 x AC/DC Power Supply ESP8266 WiFi Single-Channel Relay Module ESP-12F Development Board
1 x AC/DC Power Supply ESP8266 WiFi Single-Channel Relay Module ESP-12F Development Board
1. L, N: AC90-250V power supply
2. AC90-250V to DC5V switching power supply (Do not touch here directly with your hand when using AC power supply !!!)
3. VCC, GND: DC7-12V power supply;
4. USB: DC5V USB power supply;
Note: AC90-250V, DC7-12V, DC5VUSB can be selected as one of the three power supply methods.
5. 6X6mm button: 8266 reset button;
6. UART program download port: GND, RX, TX, 5V of 8266 are connected to GND, TX, RX, 5V of the external TTL serial module rectively. IO0 must be connected to GND when downloading, and then disconnected connection;
7. GPIO pin out port;
8. Relay output:
Normally closed end, the relay is short-circuited to COM before pull-in, and suspended after pull-in;
COM: public end;
NO: Normally open, the relay is suspended before the pull-in, and shorted to COM after the pull-in.
9. Power indication LED;
10. Programmable LED;
11. Relay Indication LED: Lights up during pull-in.
