WEMOS D1 Mini V4 ESP8266 Wi-Fi Development Board

Build a compact Wi-Fi-enabled electronics project with the WEMOS D1 Mini V4 development board. Based on the ESP8266, it combines wireless connectivity with a USB-C interface for connecting to a computer and programming compatible projects.

Start an IoT build with a small Wi-Fi board

• ✅ ✅ Add wireless control: Built-in Wi-Fi supports network-connected projects without a separate Wi-Fi module.
• ✅ ✅ Program over USB-C: Connect the board to a computer for programming with Arduino IDE or compatible tools.
• ✅ ✅ Fit it into compact builds: The mini-board format suits small IoT and automation projects.

The supplied information lists 3.3V working voltage, USB 5V input, 80/160MHz clock speed and 4MB flash memory. Confirm logic levels and pin assignments for your circuit before connecting sensors or other components.

This is the development board only; USB cable, enclosure, sensors and other project components are not confirmed as included. The product uses a Type-C connector.
