This is a compact microcontroller with multiple digital interfaces in the familiar Raspberry Pi Pico format. The main chip on board is the ESP32-S3R2 powered by an Xtensa 32-Bit LX7 Dual-Core processor offering powerful computing capability with solid security features. There's Bluetooth 5 (LE) and 2.4GHz WiFi support built-in to offer stable and reliable wireless connection options with any project you are working on! 

The interface chips are CH343 and CH334, allowing you to manage USB and UART development with a single USB-C port without switching interfaces. There is also a high-efficiency buck-boost chip to optimize circuit stability and response speed.

With substantial support for ESP-IDF, Arduino and MicroPython, including dev resources and tutorials, you will have no problem getting started!

Note: This version comes with a pre-soldered header. If you would like the version without the header then click here
