Features: This is Not a Pico, It is a Size compatible with for Pico But CPU- is different from Pico,which mean you can not run for Pico same Program.However, You can use ESP-IDF for Arduino- MicroPython to run this board The ESP32-S3-Pico is a low-cost, high-performance microcontroller development board with a compact- size and rich peripheral- interfaces. Adopts ESP32-S3R2 as the main- chip, which is an MCU chip with integrated 2.4GHz Wi-Fi and Bluetooth-compatible 5 -LE. The interface chips are CH343 and CH334, so you can experience the fun of USB and UART development with a single usbC port, and no more trouble switching interfaces. The DC-DC chip adopts MP28164, a high-efficiency buck-boost chip, which adopts PWM fixed-frequency current control mode- to optimize circuit stability and response speed.
