These development and core boards are built around the ESP32 chip, offering built-in Wi-Fi and Bluetooth connectivity. They are designed to drive a wide range of displays, including PMOLED, AMOLED, TFT, and EPD modules. The boards feature a serial interface, multiple GPIOs, and low-power consumption, making them ideal for electronic shelf labels, smart medical devices, industrial control panels, wearables, and IoT terminals. With plug-and-play compatibility and an open-source ecosystem, they speed up prototyping and simplify integration for both hobbyists and industrial developers.
