2BWK7-EL-SMELEGOO ESP-32 Development Board

PART 01 WWW.ELEGOO.COM GET THE TUTORIAL SCAN QR CODE The ESP32 is a family of highly integrated Wi-Fi (802.11 b/g/n) and Bluetooth (Classic + BLE 4.2/5.x) System-on-Chip (SoC) solutions developed by Espressif Systems (Shanghai, China). ESP32-based modules and development boards excel at reading a wide variety of inputs: Performing audio playback and simple voice-based interaction ( via integrated DAC ) 8 Audio and image data ( via dedicated peripherals or expansion boards ) 3 Remote network commands ( via Wi-Fi or BLE ) 4 Driving motors, servos, and actuators ( using PWM or dedicated driver interfaces ) 5 Uploading data to cloud platforms ( MQTT/HTTP with AWS IoT, Aliyun, Azure IoT Hub, etc. ) 6 Rendering information on displays ( I²C OLED displays, SPI TFT screens ) 7 Biometric and motion signals ( via I²C/SPI sensors such as heart-rate or IMU modules ) 2 Environmental data ( via sensors connected to ADC or digital bus interfaces ) 1 01 What Is the ESP32? Common development frameworks include Arduino Core for ESP32, MicroPython, and ESP-IDF (the official Espressif development framework). For beginners, the Arduino IDE with the ESP32 core provides the simplest entry point while retaining access to advanced ESP32 peripherals. A portable weather station that syncs real-time data to your phone via Wi-Fi. Thanks to a strong global developer community, the ESP32 ecosystem provides abundant open-source libraries, tutorials, and sample projects—such as ESPAsyncWebServer for network applications or Adafruit SSD1306 for OLED displays—making rapid prototyping easier than ever. The ESP32 gives you all the hardware foundations to turn ideas into working prototypes. WHETHER YOU WANT TO BUILD: A smart-home controller with BLE and voice commands. A battery-powered sensor node that runs for months. A Wi-Fi-controlled obstacle-avoidance robot. A wearable device for health monitoring and BLE notifications. THE ESP32 PRODUCT FAMILY : Espressif Systems, founded in 2008, released the ESP8266 in 2014—a breakthrough, low-cost Wi-Fi SoC that reshaped the IoT landscape. To address demand for multi-protocol connectivity and higher processing performance, Espressif officially introduced the ESP32 series in 2016. The first mass-produced model, ESP32-D0WDQ6, featured a dual-core Tensilica Xtensa LX6 32-bit processor with integrated Wi-Fi and Bluetooth, filling functional gaps left by the ESP8266. ESP32-S Series Optimized for low-power applications (e.g., ESP32-S3 with a RISC-V co-processor), ideal for wearables and battery-powered devices. ESP32-C Series Cost-optimized and available with integrated flash, suitable for mass-production designs. ESP32-H Series High-performance multimedia support (e.g., BLE 5.3-capable ESP32-H2), targeting cameras, displays, and edge-AI devices. 02 Evolution of the ESP32 MAIN COMPONENTS: A key milestone occurred in 2017 with the release of the Arduino Core for ESP32 , enabling millions of Arduino developers to adopt ESP32 without learning a new programming environment. Today, the ESP32 is widely regarded as the de-facto standard for mid-range IoT prototyping. This section uses the ESP32 DevKit V1 as an example to explain the core components and essential pin functions. 3V3 GND D15D2 D4 D16 D17D5 D18 D19 D21 RXD TXD D22 D23 VIN GND D13 D12 D14 D27 D26 D25 D33 D32 D35 D34UN UP EN N3 BOOT U2 I/O Connector ESP-32 I/O Connector USB to UART 5V to 3.3V Boot button Type C-USB Reset button ( ESP32 board display image ) 03 ESP32 Board Overview ESP32 Module Dual-core 32-bit processor with Wi-Fi and Bluetooth capability. Power Regulation Circuitry Converts USB or Vin supply to stable 3.3V. USB-to-UART Bridge Provides programming and serial communication via USB. POWER SPECIFICATIONS: USB Type-C / Micro-USB Ideal for development; supplies 5V input and enables code uploading. Vin pin (5–12V) Accepts external DC input; the onboard LDO regulator converts it to 3.3V for the ESP32. The ESP32 DevKit V1 supports two primary power-input methods: Important Notes 1.Do NOT exceed 12V on Vin, or the regulator and ESP32 module may be damaged. 2.All ESP32 GPIO pins operate at 3.3V logic.Do not directly connect 5V signals—use a level shifter when necessary. (1) POWER & GROUND PINS ESP32 pins are configurable through software ( multiplexed peripherals ). Below is an organized 3V3 – 3.3V Regulated Output 3.3V regulated output; useful for powering low-current sensors and modules (up to ~500mA). GND – Multiple Ground Points All external modules must share GND. Vin External 5–12V power input. (2) GENERAL-PURPOSE GPIO PINS Examples: GPIO15 (D15) Supports PWM, SPI functions. GPIO2 (D2) ADC-capable; must remain high at boot to avoid startup issues. GPIO4 (D4) GPIO with touch and ADC support. GPIO5 (D5)Often used as VSPI clock. 04 Important Pin Functions (3) UART PINS GPIO16 (RX2) / GPIO17 (TX2) UART2 communication or general I/O. GPIO3 (RX0) / GPIO1 (TX0) UART0 (USB serial) used for programming and debugging. (4) ADC / DAC / TOUCH PINS GPIO27 / GPIO32 / GPIO33 ADC inputs, some with touch sensing. GPIO34 / GPIO35 / GPIO36 / GPIO39 (VP/VN) ADC-only, input-only pins. GPIO25 / GPIO26 Support both ADC input and DAC output. (5) BUS INTERFACE PINS GPIO13/12/14 Versatile GPIOs supporting PWM, SPI, and touch ( but note GPIO12 affects boot voltage settings ). I²CGPIO21 (SDA), GPIO22 (SCL) SPI (VSPI) GPIO18 – SCK GPIO19 – MISO GPIO23 – MOSI GPIO5 – CS EN pinChip-enable; Active-high. (1) POWER & GROUND PINS ESP32 pins are configurable through software ( multiplexed peripherals ). Below is an organized Extensive hardware expandability Multiple GPIOs and peripheral interfaces suitable for diverse applications. Rich software ecosystem supports Arduino, MicroPython, and ESP-IDF; large library availability improves development efficiency. Strong community & documentation Numerous open-source examples and tutorials accelerate learning and project development.
