OUTLINE ATOM S3U is a very small and flexible IoT speech recognition development board, using Espressif's `ESP32` main control chip, equipped with two low-power `Xtensa® 32-bit LX6` microprocessors, main frequency Up to `240MHz`. It has the characteristics of compact size, strong performance and low power consumption. Integrated USB-A interface, plug and play, easy to upload, download and debug the program. Integrated `Wi-Fi` and `Bluetooth` modules, with built-in digital microphone SPM1423 (I2S), can achieve clear audio recording, suitable for various IoT human-computer interaction, voice input recognition scenarios (STT) 1.1. ESP32 S3 •The ESP32-S3 is a low-power MCU system-on-a-chip (SoC) that supports 2.4GHz Wi-F i and Bluetooth® LE dual-mode wireless communication. The chip integrates high-performance Xtensa® 32-bit LX7 dual-core processors, ultra-low powe r co processors, Wi-Fi baseband, Bluetooth baseband, RF modules, and peripherals. ESP32-S3 integrates all peripheral components seamlessly, including a crystal oscillator, flash, filter capacitors and RF matching links in one single package. Given that no other peripheral components are involved, module welding and testing is not required either. As such, ESP32-S3 reduces the complexity of supply chain and improves control efficiency. With its ultra-small size, robust performance and low-energy consumption, ESP32-S3 is well suited for any space-limited or battery-operated applications, such as wearable electronics, medical equipment, sensors and other IoT products. 2.

QUICK START 3.1. ARDUINO IDE Visit Arduino's official website(https://www.arduino.cc/en/Main/Software),Select the installation package for your own operating system to download. >1.Open up Arduino IDE, navigate to `File`->`Peferences`->`Settings` >2.Copy the following M5Stack Boards Manager url to `Additional Boards Manager URLs:` https://raw.githubusercontent.com/espressif/arduino-esp32/gh- pages/package_esp32_dev_index.json >3.Navigate to `Tools`->`Board:`->`Boards Manager...` >4.Search `ESP32` in the pop-up window, find it and click `Install` >5.select `Tools`->`Board:`->`ESP32-Arduino-ESP32 DEV Module >6Please install FTDI driver before use: https://docs.m5stack.com/en/download 3.2. BLUETOOTH SERIAL Open the Arduino IDE and open the example program `File`->`Examples`->`BluetoothSerial`->`SerialToSerialBT`. Connect the device to the computer and select the corresponding port to burn. After completion, the device will automatically run Bluetooth, and the device name is `ESP32test`. At this time, use the Bluetooth serial port sending tool on the PC to realize the transparent transmission of Bluetooth serial data. #include "BluetoothSerial.h" #if !defined(CONFIG_BT_ENABLED) || !defined(CONFIG_BLUEDROID_ENABLED) #error Bluetooth is not enabled! Please run `make menuconfig` to and en able it #endif BluetoothSerial SerialBT; void setup() { Serial.begin(115200); 3.3. WIFI SCANNING Open the Arduino IDE and open the example program `File`->`Examples`->`WiFi`->`WiFiScan`. Connect the device to the computer and select the corresponding port to burn. After completion, the device will automatically run the WiFi scan, and the current WiFi scan result can be obtained through the serial port monitor that comes with the Arduino. SerialBT.begin("ESP32test"); //Bluetooth device name Serial.println("The device started, now you can pair it with bluetoot h!"); } void loop() { if (Serial.available()) { SerialBT.write(Serial.read()); } if (SerialBT.available()) { Serial.write(SerialBT.read()); } delay(20 ); } #include "WiFi.h" void setup() { Serial.begin(115200); // Set WiFi to station mode and disconnect from an AP if it was pre viously 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)?"
