BPI-Leaf-S3


Description

The Banana Pi BPI-Leaf-S3 is a series of low-powered microcontrollers designed for IoT development and Maker DIY board.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 inputs: USB and external 3.7V lithium battery, both can be interchangable freely. The battery could also be charged while USB is plugged in. Compact size, various interface, easy to use, and can be directly applied to low-power IoT projects.

In terms of programming, the Leaf-S3 supports ESP-IDF, Arduino, micropython and other methods.

The IO pins on BPI-Leaf-S3 are identical to the Espressif ESP32-S3-DevKitC-1, developers can add peripherals that are supported by DevKitC-1 onto the BPI-Leaf-S3, and can also combine it onto a breadboard.
