Translate【Introduction to development board】
The BPI-PicoW-S3 has an onboard ESP32-S3 chip that supports 2.4 GHz Wi-Fi and Bluetooth® LE dual-mode wireless communication. The board supports two power supply modes: USB and IO power supply, which can realize the function of automatic power switching under dual power supply. Small size, convenient interface, easy to use, and can be directly applied to low-power IoT projects.
The BPI-PicoW-S3 development board supports ESP-IDF, Arduino, MicroPython and other methods for programming and development in terms of software.
All IO pins corresponding to the chip are marked on the BPI-PicoW-S3 development board, and the shape is consistent with the Raspberry Pico W development board. Developers can add peripheral devices supported by the Raspberry Pico W to the BPI-PicoW- On the S3, the development board can also be plugged into the breadboard.
