The ESP-01 is a very popular module based on the ESP8266 chipset that lets you run and control your electronic projects over WiFi. Using an ESP-01 (or any other ESP8266 variant) can be a bit tricky, as some wiring is needed to both program and access its GPIO through the module’s 2×4 pin header.

This shield makes it easy to connect the ESP-01 to any WS2812B and NeoPixel LEDs. Simply plug the ESP-01 into the shield’s 2×4 header, and easily wire GPIO2 using a separate, built-in 3-pin PH2.0 connector. The shield also offers a 2-pin male header for supplying power to the ESP-01 through an LDO regulator. The power pins are also connected to the 3-pin PH2.0 connector. It works great with 3.7V lithium batteries.
