Pin configuration:

Pin

Name

Alternate Functions

Notes

1

GND

 

(Pin 1 is in the corner close to the xtal and away from antenna)

2

NC

   

3

UTXD

SPICS1, GPIO1, CLK_RTC

Typically used as serial uart0 TX

4

URXD

I2SO_DATA, GPIO3, CLK_XTAL

Typically used as serial uart0 RX

5

GPIO16

XPD_DCDC, RTC_GPIO0, EXT_WAKEUP, DEEPSLEEP

Connected to XPD_DCDC ESP pin, can also be connected to ESP EXT_RSTB (reset) pin by closing jumper near pin 8; Reset pin is active low and has an internal weak pull-up; Connecting jumper is required to wake-up ESP from deep-sleep: RTC produces pulse on XPD_DCDC pin that needs to be fed into EXT_RSTB pin

6

CH_PD

 

Power-down: low input powers down chip, high powers up; tie high for normal operation or module will not function

7

ANT

 

Wifi Antenna, do not connect

8

VCC

 

3.3V input (pin 8 is between antenna and ESP chip)

9

GPIO14

MTMS, I2SI_WS, SP_CLK

 

10

GPIO12

MTDI, I2SI_DATA, MISO

 

11

GPIO13

MTCK, I2SI_BCK, MOSI

 

12

GPIO15

MTDO, I2SO_BCK, SP_CS

At boot: must be low to enter flash or normal boot (high enters special boot modes)

13

GPIO2

I2SO_WS, U1TXD, U0TXD

At boot: must be high to enter flash or normal boot (low enters special boot modes); Typically is used as uart1 TX for debug logging

14

GPIO0

SPICS2, CLK_OUT

At boot: low causes bootloader to enter flash upload mode; high causes normal boot

Q: this component what distance it cover..? Questioned by Farzanul, 04-Mar-2019

Q: data resive or send...? Questioned by Farzanul, 04-Mar-2019

We think there is a misunderstanding. This is not any wifi router or dongle or jammer. This is just a module which can be connected to wifi as long as it is within the network. If you want to connect any project to wifi, this is the choice. For better understanding, please see these projects done by its updated version. https://blog.techshopbd.com/category/wirelesssystems/wifi/ Answered by A.R, 04-Mar-2019 10:10 AM
