1. KB3077 Wifi module introduction
Including software, plug and play, serial
data transmission, users do not need at command secondary development;
With invention patent, mature software
system, users do not need to deal with the connection with router AP, public
network server and other issues; at the same time, support users to develop
customized software;
A variety of working modes, users choose
according to their needs;
It can be based on AP mode or station mode;
LAN and Internet communication coexist at
the same time;
The network end can be based on either
server or client;
Support SmartLink one key distribution
network;
The IP address of WiFi module can be
obtained through broadcast instruction in LAN;
The parameter configuration is convenient
and flexible, and supports three configuration modes: serial port at
configuration, LAN configuration and Internet configuration;
Equipped with internet communication
platform (cloud data server);
KB3077 is a new embedded UART-WiFi (serial port-wireless network) module introduced by Kingbot Technology. Built-in TCP / IP protocol stack, can realize the conversion between user serial port and wireless network (WiFi) interface.
Users can use the mobile phone or PC to communicate with the local area network through the KB3077 module, or connect it to a nearby WiFi router for remote communication between the mobile phone PC and the Internet, providing complete data transmission for the user's serial device through the network. Quick solution.

3.KB3077 Wifi module specifications
3.1 Electrical parameters
Working voltage: DC 5V / 3.3V
Power consumption:
The following power consumption data is based on a 3.3V power supply, an ambient temperature of 25 ° C, and is measured using an internal voltage regulator.
[1] All measurements are done at the antenna interface without SAW filters.
[2] All transmission data is based on a 90% duty cycle, measured in continuous transmission mode.
Note①: Modem-Sleep is used for applications that require the CPU to always be in a working state, such as PWM or I2S. When keeping the WiFi connection, if there is no data transmission, according to the 802.11 standard (such as U-APSD), turn off the WiFi Modem circuit to save power. For example, in DTIM3
When every 300mS sleep, wake up 3mS to receive AP's Beacon packets, etc., the overall average current is about 15mA.
Note ②: Light-Sleep is used in applications where the CPU can be suspended, such as WiFi switches. When keeping the WiFi connection, if there is no data transmission, according to the 802.11 standard (such as U-APSD), close the WiFi Modem circuit and suspend the CPU to save power. For example, in DTIM3, every 300ms of sleep and 3ms of wake-up to receive Beacon packets of AP, etc., the overall average current is about 0.9mA.
Note ③: Deep-Sleep does not need to keep the WiFi connection all the time, it only sends a packet of data for a long time. For example, a sensor that measures the temperature every 100 seconds. For example, when you wake up every 300 s and need to connect to the AP to send data in 0.3-1s, the overall average current can be much less than 1mA.
