ESP32 Mini D1 WiFi Bluetooth Module ESP-WROOM-32 with Battery Interface

The ESP32 Mini D1 (also known as WeMos D1 ESP32) is a compact development board based on the ESP-WROOM-32 module. It features a dual-core processor, WiFi connectivity, and Bluetooth support, making it an ideal platform for IoT projects while maintaining a breadboard-friendly form factor.

This version includes a dedicated interface for lithium-ion or lithium-polymer (Li-Po) batteries, enabling extended autonomy for mobile applications. The charging current is limited to 500 mA to ensure battery safety and longevity. The board is equipped with 4 MB of flash memory for storing your code and necessary data.
