BPI-Leaf-S3 has an onboard ESP32-S3 chip, supports 2.4 GHz Wi-Fi and Bluetooth LE dual-mode wireless communication, is compatible with low- hardware design, and consumes only 10uA in sleep mode .It supports two supply modes: USB and external 3.7V lithium battery, which can realize automatic switching function under dual supply, and supports USB charging mode. Small size, convenient interface, easy to use, and can be directly applied to low- IoT projects.The BPI-Leaf-S3 development board supports for ESP-IDF, for , for MicroPython and other methods for programming and development in terms of software.All IO pins corresponding to the chip are marked on the BPI-Leaf-S3 development board, and the order of the IO pins is with the Espressif ESP32-S3-DevKitC-1 development board. Developers can support DevKitC-1 according to actual needs. The peripherals are added to the BPI-Leaf-S3, and the development board can also be plugged into the breadboard.color:BlackMaterial:PCBPackage Contents:1 x Development BoardOnly the above package content, other products are not included.Note: Light and different displays may the color of the item in the a little different from the real thing.
