The Raspberry Pi have far exceeded the stage of computers to learn computer science. They have been integrated into the daily life of millions of users for all kinds of projects: multimedia controller, weather station, home automation control tower… In more than ten years of existence, many versions have been released, always with the desire in mind. to offer the most affordable prices possible.
In January 2021, the British manufacturer caused a sensation by launching the Raspberry Pi Pico, its cheapest computer. And when we say the cheapest, it’s not a pipe since the small motherboard costs less than 5 €! The success was there with more than 2 million units sold.
Cheap and versatile
For this price, impossible to ask for the Moon, but there was at least one function that the computer was sorely lacking: Wi-Fi. It is now fixed with the Raspberry Pi Pico W, which integrates support for wireless. thread, all for the modest sum of €6.99! It is the addition of a CYW43439 chip from Infineon which allows the computer to access Wi-Fi, in this case 802.11b/g/n on the 2.4 Ghz band.
The rest of the data sheet does not change from one model to another, we find in the W card the same characteristics as on the previous model: RP2040 chip which embeds two ARM Cortex-M0+ cores clocked at 133 MHz, 256 KB of RAM, 2 MB of Flash memory and 26 multi-function GPIO pins.
The Raspberry Pi Pico W also features low-power standby and sleep modes, supports USB 1.1, and includes a temperature sensor. The manufacturer has also added the Pico H to the range, without Wi-Fi but with pre-soldered GPIO pins for €6. And as usual with Raspberry Pi, all the documentation is provided to start developing around these computers.
