D-Duino-32 II Dual Screen ESP32-WROOM-da Development Board Description

ESP32-WROOM-DA is a powerful Wi-Fi + Bluetooth + Bluetooth LE MCU module, with two complementary PCB antennas in different directions. I customized the 16MB memory version and designed this development board around it.
With two antennas design on one single module, ESP32-WROOM-DA can be used to develop IoT applications that need stable connectivity over a broad spectrum, or to deploy Wi-Fi in challenging and hazardous environments, or to overcome communication problems in Wi-Fi-dead spots. This module is an ideal choice for indoor and outdoor devices for smart home, industrial control, consumer electronics, etc.
Equipped with a 128x64 dual OLED screen, data monitoring and interactive interface are displayed simultaneously.
Equipped with a built-in DS3231 chip (with 2ppm accuracy) and a MicroSD card slot, it ensures precise data recording and massive storage (supporting FAT32/exFAT formats).
Integrated 5V/1A Type-C fast charging and lithium battery management (charge and discharge efficiency 85%), power module supports 5-12V wide voltage input, ensuring no power interruption for outdoor projects.

The 17 GPIO pins can be connected to sensors, and it is compatible with for the /PlatformIO ecosystem.
There are schematic diagrams, test source codes, etc. in the SD card. Please back up the contents of the SD card in advance.
