## Description

Compact development board for rapid prototyping and IoT or robotics projects, based on the Raspberry Pi RP2040 dual-core at 133MHz, with 2MB flash and 264KB SRAM. It offers 3.3V I/O with digital and analog GPIOs, PWM and I2C, UART, SPI interfaces, plus USB Type-C for easy programming in Arduino, MicroPython or CircuitPython.
The development board equipped with the Raspberry Pi RP2040 chip, Seeed Seeeduino XIAO RP2040, is designed to be compatible with the Arduino, MicroPython and CircuitPython platforms. It offers an efficient and versatile solution for the development of electronic projects and robots, bringing together the power and flexibility of Raspberry Pi chips and the ease of use of Arduino development platforms.
Through the RP2040 chip, the board offers a dual-core architecture with two ARM Cortex-M0+ cores, which makes it capable of managing complex tasks and offering outstanding performance. This development board has 264KB of SRAM memory and 2MB of flash memory, thus providing enough space for storing code and data.
Seeeduino XIAO RP2040 comes with a variety of interfaces for connecting peripheral components and sensors. It includes digital and analog GPIO pins, PWM pins and I2C, UART and SPI interfaces. It also has a USB Type C (Type-C) interface for programming and communication with the computer, which facilitates the process of developing and debugging applications.
The board supports multiple programming languages, including Arduino, MicroPython and CircuitPython, allowing programmers and hobbyists to use the development environment they feel most comfortable with.
The board offers a button for Reset and one for Boot. It has a programmable RGB LED (USER programmable), a power LED, two status LEDs and a user LED.
The board can be programmed with the Thonny editor, just like a Raspberry Pi Pico.
The I/O pins are on 3.3V. Do not use more than 3.3V, otherwise the board will burn. For use with 5V sensors and modules, use a logic level translator.
