The Banana Pi Leaf series are low-power microcontrollers designed for the Internet of Things. Maker and STEAM education.
The Leaf-S3‘s onboard ESP32-S3 chip is powered by an Xtensa® 32-bit LX7 dual-core processor with a main frequency of up to 240 MHz.
It supports 2.4 GHz Wi-Fi and Bluetooth® LE dual-mode wireless communication, the peripheral is compatible with low-power hardware design, and the power consumption is only 10uA in deep sleep mode.The main controller supports two power supply modes: USB and external 3.7V lithium battery, which can realize the function of automatic power switching under dual power supply, and supports USB charging mode. Small size, convenient interface, easy to use, and can be directly applied to low-power IoT projects.In terms of programming, Leaf-S3 motherboard supports ESP-IDF, Arduino, micropython and other methods for programming and development.All IO pins corresponding to the chip are marked on the Leaf-S3 motherboard, which lowers the threshold for use.
