Figure 16: The onboard circuit configuration refer to LED, WPS, TX pinout.

Notes:

 TX or WPS pin is internally pulled up with an onboard 4.7K ohm resistor to 3.3VDC .It is low level

(can be connected to ground) activated.

 LED outputs 3.3V blink signal, the LED operation current is limited via the 330 ohm resistor.

If the onboard and external LEDs must be used simultaneously, proper LEDs’ operation current

must be considered, If necessary, the internal onboard LED can be removed while ordering.
