ESP8266 and ESP32 Expansion Boards

ESP8266 and ESP32 expansion boards mount onto standard development boards, adding Grove-compatible sensor connectors, servo headers, screw terminals, and power regulation that simplify connecting external hardware without breadboard wiring.

The range includes expansion shields for NodeMCU and Wemos D1 Mini with multiple Grove ports, prototyping shields with solder pads, and dual motor driver expansion boards for robotics applications.

Expansion boards are used by makers building IoT sensor arrays who need to connect multiple Grove modules cleanly, by educators setting up class kits where students connect sensors without wiring errors, and by robotics builders who want servo and motor control alongside ESP32's WiFi connectivity in a single tidy package.
