It uses the Espressif ESP32 as the main control chip, integrates a Wi-Fi solution, and is equipped with a dual-core low-power Xtensa® 32-bit LX6 microprocessor with a clock speed of up to 240MHz. It comes with 16MB Flash and integrates a 240 x 135 1.14-inch full-color HD IPS display panel, physical button panel, rich peripherals, and two sets of six expansion interfaces. It also features low-power sleep/timed wake-up functionality. It supports multiple power supply methods, including USB Type-C, PWR485, and an internal rechargeable battery (battery socket reserved on the board). The board integrates a high-power-density fully integrated boost DC/DC converter SCT12A0DHKR, ensuring stability in complex application scenarios. This controller is suitable for various application scenarios such as industrial field control, smart buildings, multi-channel data acquisition nodes, and developer prototyping.
