    ESP WROOM 32 with 0.96 128×64 OLED.
    This module is based on ESP Wroom 32 and SSD1306 OLED display (I²C). Since there was no documentation given on the site, I decided to blindly try the OLED example code provided with ESP-IDF (v5.2.2) + Espressif-IDE for Linux (WSL Ubuntu).
    esp-idf/examples/peripherals/lcd/i2c_oled at master · espressif/esp-idf · GitHub
    Surprisingly it turned well, had to modify only one line of code in i2c_oled_example_main.c -> changing EXAMPLE_PIN_NUM_SDA from pin GPIO3 to GPIO5. OLED_SDA = GPIO5 & OLED_SCL = GPIO4 respectively. The ESP32 example uses LVGL library for OLED display.
    I haven’t yet tried BT & Wi-Fi sections or the SPI/Parallel interface for OLED.
    PCB quality looks ok, but found some residues of solder flux on them. They should have cleaned with Alcohol or something.
    The Boot and Reset buttons are located on bottom side of the PCB. Depending on your system configuration, you may have to download driver for CP210x USB to UART converter.

    The best board ever to kick start the IoT projects & stuff. Will be much better if Robu provides a small documentation pertaining to the board specs & stuff.
