Microcontroller Raspberry Pi Pico - RP2040 ARM Cortex M0+

Raspberry Pi Pico - RP2040 ARM Cortex M0+

A compact Raspberry Pi Pico module with Raspberry 's own RP2040 microcontroller made in the UK. The RP2040 is a dual core ARM Cortex M0+ based chip clocked at 133 MHz. The module has 264 kB of SRAM memory and 2 MB of Flash memory. The chip features 26 GPIO pins that operate at 3.3 V and a temperature sensor. Raspberry Pi Pico is programmed in C/C++ language, via microUSB connector.

Pinouts of Raspberry Pi Pico module

The Raspberry Pi Pico module is equipped with 26 GPIO pins, which include: 2x SPI, 2x I2C, 2x UART, 3x ADC 12-bit, 16x PWM. An additional 8 IO (PIO) pins are provided to support custom peripherals.

Power supply for Raspberry Pi Pico

The microUSB connector is used to power and communicate the Raspberry Pi Pico board with the computer. A 5V power supply is required for the module to work properly. The board can also be powered from VSYS pin with 1.8V to 5.5V using e.g. 3.7V Li-Pol battery or 3x AA battery.

First steps with MicroPython

The Raspberry Pi Pico can be programmed by connecting it to a computer via USB cable by dragging and dropping a file. A downloadable UF2 file has been prepared to help you get started with MicroPython.

• Download the MicroPython UF2 file.
• Press and hold the BOOTSEL button and connect the board to the USB port of your Raspberry Pi or computer.
• Release the BOOTSEL button once the Pico is connected to your computer.
• The Raspberry Pi Pico will be mounted as a storage device with the RPI-RP2 volume.
• Drag and drop the MicroPython UF2 file onto the RPI-RP2 volume.
• Pico will restart, now MicroPython will be used.
• You can access the REPL and MicroPython through the serial USB port.
