10PCS D1 Mini ESP32 IoT Development Board, WiFi & Bluetooth Dual Wireless, Upgrade Replacement for ESP8266, Full Functions

This package contains 10 pieces of D1 Mini ESP32 development boards, an upgraded IoT control board built on the classic ESP8266 D1 Mini layout. Unlike ESP8266 that only supports WiFi, this ESP32 version combines 2.4GHz WiFi and Bluetooth dual wireless communication for richer wireless interaction.

It retains the compact D1 Mini size and unified pin definition, so you can directly swap it with original ESP8266 D1 Mini without modifying existing enclosures or wiring. Every functional GPIO is fully led out, supporting easy connection with sensors, relays, OLED screens, motor drivers and other peripherals.

All core functions are fully realized onboard without extra expansion modules required. It works seamlessly with the Arduino development environment for quick secondary development. Perfect for smart home devices, wireless monitoring nodes, student electronic experiments, robot controllers and mass prototype testing for maker workshops and small batch DIY projects.
