This board has 16 MB flash memory! 4 times as more as most current boards available. With new versions of expressif libraries coming up and popular projects like WLED offering more and more functionality 16MB is preferable to catch up with this.

Product Description

This development board features, the powerful ESP-WROOM-32 module, with integrated WiFi and Bluetooth functionality (BR/EDR/BLE). The ESP32 is a chip designed with TSMC ultra-low power management technology.

Current of the ESP32 chip is less than 5 μA, it is particularly well suited for use with batteries or rechargeable batteries. The ESP32 D1 Mini has a similar pin layout to the conventional D1 Mini ESP8266-12F and is therefore pin compatible with most accessories for it. The proven ESP32-D0WDQ6 chip is located in the core of the developed module.

Why 16MB

• 16MB flash, four times what most dev boards include
• enough space to store WLED with many usermods,
• future safe, as WLED code will grow and 4mb is already limiting
• recommended for development, as debug informations need more flash
• extra file storage, for example to store .fseq animations (usermod in work)
