Banana Pi BPI-PicoW-S3 is an open source hardware development board designed for IoT development and maker DIY. Designed with Espressif ESP32-S3 chip, it supports 2.4 GHz Wi-Fi and Bluetooth® LE dual-mode wireless communication. The peripherals are compatible with low-power hardware design, and the power consumption in deep sleep mode is only 10uA. In terms of programming, BPI-PicoW-S3 supports ESP-IDF, Arduino, micropython and other methods.
The size is exactly the same as the Raspberry Pi pico, and most GPIO definitions are compatible with the Raspberry Pi pico
