The ESP32 OLED Module combines WiFi and Bluetooth functionalities with a 0.96″ OLED display, utilizing the ESP-WROOM-32 WiFi module. It stands out from Arduino’s limitations with its 512KB of memory and dual-core 240MHz processor, providing ample computing power. Additionally, it integrates a Bluetooth 4.2 (BLE) module, making it particularly well-suited for IoT applications. Programming the NodeMcu follows a slightly different approach than traditional methods, resembling NodeJS with commands executed via LUA scripts uploaded to the module. This product is available under various names: NodeMcu ESP32 OLED Module, WeMos Lolin ESP32 OLED Display Module for Arduino, ESP32 ESP-WROOM-32 0.96″ Inch OLED Display 2.4GHz WiFi Bluetooth Dual Mode Development Board Module, and others, emphasizing its versatility as a development board equipped with both WiFi and Bluetooth capabilities. Note: Please install the driver for the CP210x USB to UART converter. Features of ESP32 OLED Module: Processor: Dual-Core Tensilica LX6 Microcontroller SRAM: 520 WIFI: 802.11 b/g/n Flash Memory: 4 MB High performance Integrated antenna and RF Balun Power amplifier Low Noise Amplifiers Power Management Module 2.4 GHz dual WiFi and Bluetooth chips Easily embedded in other products Strong function, with the support of lwIP protocol, freeRTOS Support three modes: AP, STA, and AP STA Support for lua program, easy to develop Programming: 1. Install ESP-IDF and VS Code Setup Download and install Visual Studio Code. Install the Espressif IDF extension from VS Code Marketplace. Run the ESP-IDF: Configure ESP-IDF extension command in VS Code and follow the guided setup to: Download ESP-IDF (choose latest stable release). Set Python environment. Configure ESP-IDF tools. 2. Open Example Project In VS Code, press Ctrl Shift P (Windows/Linux) or Cmd Shift P (Mac). Run: ESP-IDF: Show Examples Projects. Search for: peripherals/lcd/i2c_oled Select it and create a new project in your workspace (e.g., ~/esp/i2c_oled_project). 3. Modify SDA & SCL Pin Configuration Open the file: main/i2c_oled_example_main.c Locate the following definitions: #define EXAMPLE_PIN_NUM_SDA GPIO3 Change them to use your required pins: #define EXAMPLE_PIN_NUM_SDA GPIO5 ✅ This sets OLED_SDA = GPIO5 and OLED_SCL = GPIO4. 4. Build & Flash 5. Demo https://chiptronicx.com/wp-content/uploads/2024/07/ESP32-OLED-Module-for-WiFi-and-Bluetooth-Demo.mp4 Package Includes: 1 x ESP32 OLED Module for WiFi and Bluetooth Related
