Note 1: The module enables high level by default.
Note 2: You can only choose one of 3V3 power supply and 5V power supply! ! !
Note 3: IO39 and IO36 only support input.
Power supply characteristics:
The power supply voltage of the module can be 5V or 3V3, and only one of the two can be selected.
Power supply mode, Users can freely choose according to their needs:
- 1) Through hole (welding header):
Use DuPont line connection for power supply;
Use breadboard connection for power supply;
- 2) Half pad (directly soldered to the board): the user board provides power.
Instructions for use:
- Power-on instructions
If
the DuPont line is used: find the 3V3 or 5V power input port, connect
the corresponding voltage, the indicator light (LED1) lights up,
indicating that the Electric success.
- Indicator light description
LED1: power indicator, power on normally, the light is on;
LED3: serial port indicator light, when RXD2 (IO35) has data flow, the light is on;
LED4: serial port indicator light, when TXD2 (IO17) has data stream, the light is on;
There are three ways to use, users can choose according to their needs:
- 1) Through hole (welding pin header): use DuPont wire to connect;
- 2) Through hole (welding header): put it on the breadboard for use;
- 3) Half pad: Users can directly solder the module on their own board.
Description of network port working indicator:
- Green light: Connection status indicator When connected to the network correctly, the green light is on
- Yellow
light: data indicator flashes when the module receives or sends data,
including the module receives a network broadcast packet
