Description
This is a universal WIFI plus Bluetooth development board based on ESP32, integrated with ESP32-WOROOM-32 module and compatible with Arduino.
It has a hall sensor, high-speed SDIO/SPI, UART, I2S as well as I2C. Furthermore, equipped with freeRTOS operating system, which is quite suitable for the Internet of things and smart home.
Specifications
- Voltage: 3.3V-5V
- Current Output: 1.2A(maximum)
- Maximum power Output: 10W
- Working temperature: -10℃~50℃
- Dimension: 69*54*14.5mm
- Weight: 25.5g
- Environmental protection attributes: ROHS
Pin out
Schematic Diagram
If you are a beginner, please refer to the file Get Started with Arduino to install the ESP32 development board driver and Arduino IDE as well as the ESP32 development environment.
Test Code
#include "WiFi.h"
void setup(){
Serial.begin(115200);
// Set WiFi to station mode and disconnect from an AP if it was previously connected
WiFi.mode(WIFI_STA);
WiFi.disconnect();
delay(100);
Serial.println("Setup done");
}
void loop(){
Serial.println("scan start");
// WiFi.scanNetworks will return the number of networks found
int n = WiFi.scanNetworks();
Serial.println("scan done");
if (n == 0) {
Serial.println("no networks found");
}
else {
Serial.print(n);
Serial.println(" networks found");
for (int i = 0; i < n; ++i) {
// Print SSID and RSSI for each network found
Serial.print(i + 1);
Serial.print(": ");
Serial.print(WiFi.SSID(i));
Serial.print(" (");
Serial.print(WiFi.RSSI(i));
Serial.print(")");
Serial.println((WiFi.encryptionType(i) == WIFI_AUTH_OPEN)?" ":"*");
delay(10);
}
}
Serial.println("");
// Wait a bit before scanning again
delay(5000);
}
After uploading the code, the ESP32 will find nearby WIFI and print the name and signal strength via the serial port each 5s.
Test Result
After uploading the code, open the serial port and we can see the wifi found by ESP32.
