Product information "WiFi3 click"

WiFi3 click is a complete self-contained WiFi solution carrying the ESP8266 module with a system on a chip. The click is designed to run on a 3.3V power supply only. It communicates with the target board microcontroller through the mikroBUS™ RX, TX, CS and RST lines.

ESP8266 WiFi module

The module supports standard IEEE802.11 b/g/n agreement and has an integrated TCP/IP protocol stack.

It also integrates antenna switches, an RF balun, power amplifier, low noise receive amplifier, power management modes and more.

The Standby power consumption of < 1.0mW is ideally suited for IoT projects and devices that need long battery life.

Ideally suited for IoT applications

WiFi3 click is ideally suited for IoT applications. The System on Chip offloads all the networking functions from the MCU. You can integrate it with sensors and actuators through its GPIOs and connect your things to the internet with minimum development effort.

PCB antenna

WiFi3 click features a PCB trace antenna, designed for the 2400–2483.5 MHz frequency band.

Code snippet

The following code snippet shows the interrupt routine for receiving characters from the WiFi3 module.

01 void UART3_Interrupt() iv IVT_INT_USART3 ics ICS_AUTO
02 {
03     tmp = UART3_Read();
04     switch(tmp)
05     {
06     case LF:
07         if(data_len > 1)
08         {
09             data_ready = 1;
10         }
11         break;
12     case CR:
13         rx_buff[data_len] = 0;
14         break;
15     default:
16         rx_buff[data_len] = tmp;
17         data_len++;
