If all we are doing is collecting temperature / humidity and air pressure data, do we need a Linux OS? General use of the Raspberry Pi Pico W It is cheap, low power and can be used with many of the sensors and inputs used on the Zero W. Computationally, the Pico W is slow, even compared to the Zero W, but if we don’t need the horsepower and bloat of a full Linux OS, or if your project doesn’t need a camera, then the Pico W makes sense. The nearest Raspberry Pi we can compare to the Raspberry Pi Pico W is the original Raspberry Pi Zero W and its newer incarnation the Raspberry Pi Zero 2 W. But for the original $4 price point there had to be a sacrifice, and Wi-Fi was it. This is what the Raspberry Pi Pico should’ve had from day one. Though we have plenty of experience with MicroPython’s network module, even a beginner would be able to write and understand the five lines of code needed to make the connection. The ease with which we got online was astounding. All of this is done on a $6 microcontroller instead of a $10 to $15 single board computer. We no longer have the overhead of a full Linux OS to deal with. Why is this important? Well now we have a $6 IoT board from Raspberry Pi Ltd that can use a plethora of sensors and then send the data over a reliable network, where it can be collated and worked on. How long until some enterprising hackers enable Bluetooth on the Pico W for themselves? We shall wait and see. Upton told us that Bluetooth is not as of yet enabled in the Pico W’s firmware. Looking at Infineon’s datasheet for this chip, we spotted that it also is capable of transmittingBluetooth 5.2, but in the Raspberry Pi documentation, there is no mention of this. The only difference is the inclusion of Infineon’s CYW43439 2.4-GHz Wi-Fi chip. We have the same GPIO, microUSB port, dimensions and SoC. Infineon CYW43439 2.4 GHz Wi-Fi with onboard antennaĪs you can see there isn’t really much difference between the original Raspberry Pi Pico and the new Pico W.
