2.Design specification

  1. Module power supply consumption:3.3V/100mA, instantaneous current(5us) 450mA. Proposed supply current≥300mA.
  2. Power filter capacitor C1 & C2 should be distributed as close to the 3.3V power pin as possible.
  3. Serial port TXD0 & RXD0 are user interface. Default setting Baud rate: 9600, Data level: 8 bit, Stop bit: 1 bit, No check bit, No flow control. If you need to use serial port as a common IO port, please contact with the technician.
  4. TOUT pin is ADC pin, can’t be used as an ordinary IO port. If idle, plesase suspend.
  5. RST pin is module reset pin, effective under the low level. It can be suspended processing as it has contained a pull-up resistor.
  6. LED2 pin is the relay status indicator, when IO port output is the low level, the indicator light is on.
  7. LED1 pin is the WIFI status indicator, when IO port output is the low level, the indicator light is on.
  8. Reset is button, effective under the low level. The button is effective to switch the relay when pressed in short time. The button is effective to clear the WIFI configuration function when pressed in long time(5s).
  9. RELAY control coil of the relay, module IO port drive capacity is 12mA, please pay attention to the difference between module IO drive capability and the relay required drive current.
  10. Other idle pins can be used for suspended processing.
  11. Module defaults to in-line mode, in order to ensure the optimization of Wi-Fi performance. It is recommended that the distance between antenna section and other metal parts should be at least 15mm in the module.
