Banana Pi BPI-PicoW-S3 is a low-powered microcontroller designed for IoT development and Maker DIY boards. It is designed with an ESP32-S3 chip and 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 10 uA in deep sleep mode. In terms of programming, the BPI-PicoW-S3 supports ESP-IDF, Arduino, micropython and other methods.

It is the same size as the Raspberry Pi Pico, and most GPIO definitions are compatible with Raspberry Pi Pico.
