The for Leaf is a series of low-powered microcontrollers designed for IoT development. 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 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, for , micropython and other methods. The IO pins on -Leaf-S3 are identical to the for ESP32-S3-DevKitC-1, developers can add peripherals that are supported by DevKitC-1 onto the -Leaf-S3, and can also combine it onto a breadboard.
