BPI%20Leaf-S2%201

The Banana Pi BPI-Leaf Series is a low-powered microcontroller designed for IoT development purposes. The Leaf-S2 has Xtensa® 32 bit LX7 single core processor on board with frequency up to 240 MHz. It features Wi-Fi connection and supports various peripherals. The board can be powered via USB or 3.7V lithium battery. The compact size, an abundance of IO, and user-friendly interface are a great fit for low-power consumption IoT projects. It is also compatible with the Arduino IDE. Programming-wise, it supports Arduino, idf(linux), and MicroPython. These features combined with marked IOs makes this all in all very user-friendly.

N otice : The ESP32 is aimed towards developers, not all peripherals are provided with example codes. Potential bugs are yet to be tackled. In the Arduino IDE environment, IO pins and I2C/SPI are enabled and can be used directly, other features are still under development. BPI%20Leaf-S2%203
