ACROBOTIC ESP8266 WeMos D1 Mini Pro Development Board (16 MB Flash)

Regular price $8.99

The WeMos D1 Mini Pro Development Board includes the ESP8266 SoC, USB-to-Serial (CH340G) IC, and all the necessary passive components, comes ready for plugging into your computer's USB port and loading up custom firmware.

Similar to other ESP8266 development boards such as our DevKit and the WeMos D1 Mini offers an inexpensive solution for making internet-connected devices. Different than our D1 Mini V2, the D1 Mini Pro carries 16MB of Flash Memory as well as a connector for an external antenna. Its small footprint and accompanying wide range of shields—compatible with the D1 Mini V2 shields—make it an ideal solution for quickly prototyping IoT projects in a compact amount of space.

Overall, the WeMos family of boards is a great addition to the ESP8266-based Internet Of Things (IoT) ecosystem.
