This new edition has NXP's MPXV5010DP sensor which is an integrated on-chip silicon pressure sensor that is signal-conditioned, temperature compensated and calibrated. Two axial ports are included in the Pressure Sensor Board for Pico to allow industrial-grade tubing. The sensor's maximum error rate between 0 and 85 degrees Celsius is 5.0%. It communicates with the target microcontroller over the SPI interface (CS, SCK, MISO). Pressure Sensor Board for Pico W is made to compare two pressure readings. Taking the difference in gas pressure in a flow tube with different diameters, for instance.
This github provides getting started guide and other working details for Pressure Sensor Board for Pico W

- Every board will be provided with boot firmware already installed on Pico W, so you can skip this step and directly go to step 2.
- If in case you want to install firmware for your board, Push and hold the BOOTSEL button and plug your Pico W into the USB port of your computer. Release the BOOTSEL button after your Pico is connected.
- It will mount as a Mass Storage Device called RPI-RP2.
- Drag and drop the MicroPython UF2 - Firmware file provided in this github onto the RPI-RP2 volume. Your Pico will reboot. You are now running MicroPython on ArdiPi.
-
Download Thonny IDE from Download link as per your OS and install it.
-
Once done start Thonny IDE application, Connect Pico W onboard to laptop/PC.
-
Select device at the bottom right with a suitable COM port, as shown in the below figure. You might get a different COM port.
-
Write simple onboard blink Python code or Download Led blink code, then click on the green run button to make your script run on Pico W.
Now that we've reached this point, you're executing your script through Thonny IDE, so if you unplug Pico W, it will stop running. To run your script without using an IDE, simply power up Board and it should run your script, go to step 3. Once you have transferred your code to the Pressure sensor board, to see your script running, just plug in power either way using micro USB or via Vin, both will work.
-
Click on File -> Save Copy -> select Raspberry Pi Pico , Then save file as main.py
In similar way you can add various python code files to Pico. Also you can try out sample codes given here in examples folder.
-
But in case if you want to move multiple files at one go, example suppose you are interested to save library files folder into Pico W, below image demonstrate that
NOTE: Don't rename lib files or and other files, only your main code script should be rename as main.py for standalone execution without Thonny.
Save whatever example code file you want to try as main.py in Pico W as shown in above step 3, also add related lib files with default name if required any. In example folder you will find demo example script
- Buzzer : code to test onboard Buzzer
- Display : Display working demo code
- Pressure Sensor: Demo code to test Pressure sensor
Using this sample code as a guide, you can modify, build, and share codes!!
