Small Raspberry Pi Pico module with proprietary Raspberry RP2040 microcontroller with CYW43439 wireless system. The RP2040 is a dual-core ARM Cortex M0+ chip running at 133 MHz with 264 kB of SRAM and 2 MB of Flash memory. CYW43439 enables wireless WiFi IEEE 802.11 b/g/n communication. The system has 26 GPIO pins that operate at 3.3V and a built-in temperature sensor. Raspberry Pi Pico is programmable in C/C++ and MicroPython via a microUSB connector.
Raspberry Pi Pico W Module Pins
Raspberry Pi Pico W comes with 26 GPIO pins. Among them you can find such interfaces as: 2x SPI, 2x I2C, 2x UART, 3x ADC 12-bit, 16x PWM. The module is additionally equipped with 8 programmable IO pins (PIO) to support non-standard peripheral devices.
Raspberry Pi Pico W Power Supply
The board has a built-in microUSB port, which is used both for power and for communication between the Raspberry Pi Pico W board and the computer. The module requires a 5V power supply with a power supply of 1.8V to 5.5V using e.g. a 3.7V Li-Pol battery.
Raspberry Pi Pico W Programming
Raspberry Pi Pico W is programmed in C/C++ or MicroPython. To load the program on the board, press and hold the BOOTSEL button and connect the Raspberry Pi Pico to the computer with a microUSB cable. The computer will detect the module as a USB mass storage device named RPI-RP2, the program file needs to be dragged to the newly found volume.
Getting started with MicroPython
Raspberry Pi Pico W is programmed by connecting to a computer via a USB cable, dragging the file with the program code to the newly created volume. A sample UF2 file is also available for download 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 the Raspberry Pi or computer.
- Once the Pico is connected to the computer, release the BOOTSEL button.
- The Raspberry Pi Pico will be detected as a mass storage device with a volume of RPI-RP2.
- Drag and drop the MicroPython UF2 file onto the RPI-RP2 volume.
- Pico will restart, MicroPython will now be used.
- You can access the REPL and MicroPython through the serial USB port.
Hello World C/C++
The first program every programmer writes is Hello World, in this case the Raspberry Pi Pico W will be programmed through the USB serial port of the Raspberry Pi 4B.
- Download the UF2 Hello World file.
- Press and hold the BOOTSEL button and connect the Raspberry Pi Pico to the USB port of the Raspberry Pi.
- The board will be detected as a mass storage device with a volume of RPI-RP2.
- Drag and drop the UF2 file onto the RPI-RP2 volume.
- Pico will restart.
- Open a terminal on your Raspberry Pi 4B and run the commands:
- sudo apt install minicom
- minicom -b 115200 -o -D /dev/ttyACM0
- You should see Hello World in the terminal window.
