The driver board is compact and is a microcontroller development board equipped with 40PinSPI+RGB interface and 18PinSPI screen interface. It integrates large-capacity Flash and PSRAM, connects to the screen through two screen interfaces, and can smoothly run GUI interface programs such as LVGL. In terms of hardware, it uses the ESP32-S3-WROOM-1-N8R8 module, which is equipped with an Xtensa 32-bit LX7 dual-core processor with a main frequency of up to 240MHz, built-in 512KB (TCM) and 8MB PSRAM; on-board efficient charge and discharge management chip ETA6096 and MX1.25 lithium battery interface, the pin header interface is compatible with 18Pin SPl screen, and can be compatible with the expansion of various peripheral devices, which is easy to use. In terms of software, you can choose for -IDE, ESP-IDF and other development environments for development, so that you can easily and quickly get started and apply it to products. The stamp hole design can be directly welded and integrated into the base plate designed by the user. Adopts ESP32-S3-WROOM-1-N8R8 module, equipped with Xtensa 32-bit LX7 dual-core processor, main frequency up to 240MHz Integrated 512KB , 384KB ROM, 8MB PSRAM, 8MB Flash memory Integrated 2.4GHz Wi-Fi and low-power Bluetooth (Bluetooth LE) dual-mode wireless communication, with excellent RF performance Adopts USB Type-C interface, no need to worry about the positive and negative insertion Equipped with 40Pin and 18Pin screen interface, strong compatibility and scalability Supports multiple low-power working states, can adjust the balance between communication distance, data rate and power consumption, and meet the power consumption requirements of various application scenarios Colour:Black Material:PCB Package Contents: 1 * Driver Board 1 * Straight Pin Only the above package content, other products are not included.
