Finally, it's time to ！ After a year and a half , Raspberry pie Launch new products again ：

Pi Pico W, In old style Pi Pico On the basis of , Added Wi-Fi function , Support **Pi Pico W, Raspberry pie's latest microprocessor development board , Compared with the previous generation, new Wi-Fi 4 Wireless capabilities .

The price only needs 6 dollar （ Renminbi conversion 40 element ）.

New products have just come out , Open officially authorized sales channels , One day on the market stock It's gone ……

The new product of the official twitter account is tweeted like 2000+：

Netizens are also hi , Like this old man ：

Like the clouds in the face of drought .

There are also netizens who have filled in various usage scenarios .

besides , Raspberry pie also brings two other new products ：Pi Pico H and Pi Pico WH, The selling prices are 5 The dollar and 7 dollar .

The biggest difference , Is in the Pi Pico and Pi Pico W A pre filled needle base is added on , More convenient connection .

See together .

Pi Pico W increase Wi-Fi function

Last year 1 The old model released in January Pi Pico comparison , The new Pi Pico W, The biggest change is the increase Wi-Fi function .

The hardware of wireless module is Infineon CYW43439 Wireless chip , Can support Wi-Fi 4 Wireless network , Allow to use 2.4 GHz and 5 GHz Two radio bands , At the same time, it can provide 600 Mbps The speed of data transmission .

increase Wi-Fi After function , Wireless network control and transmission will become very convenient .

For example, use the old style Pi Pico To control a row LED The lamp , If no additional wireless communication accessories are added , It can only be realized by physical switches , But through Pi Pico W, You can go through Wi-Fi Connect PC Control of equipment .

in addition , The new product is equipped with CYW43439 The wireless chip also supports Bluetooth function , but Pi Pico W Bluetooth is not enabled yet , The specific reasons are not disclosed , But raspberry pie officials also said ：

future May open Bluetooth .

besides ,Pi Pico W It is basically the same as the old model , The computing core is still RP2040 Micro controller .

While releasing new products , Raspberry pie officials also released guidelines for the use of wireless connectivity .

about C Language users Come on , Abreast of the times Pico SDK Including wireless network support , The network stack surrounds lwIP establish , Use at the same time Damien George Of libcyw43 Library to communicate with wireless chips .

MicroPython Users are relatively troublesome , Need to download an updated UF2 Image to support Pico W The Internet of things , While connecting USB after , Enter the following code at the serial terminal ：

And then you can go in REPL see Wi-Fi Access list .

Raspberry pie officials also said ,C Language and MicroPython How to get started , as well as API Level document links , Can be found in the official documentation website .

in addition , In the next month or two , The official will also launch more demonstration documents , Convenient for users .

Last , And the most important , How much is it? ？

The official answer is ：6 dollar , Renminbi conversion 40 yuan .

It doesn't look too expensive , But compared with the previous generation Pi Pico Of 4 The price in US dollars Rise 50%, The increase is not small .

Regarding this , CEO of raspberry pie Eben Upton Express , by Pi Pico W The development cost of increasing wireless communication capability is relatively high , Just solving the radio compatibility problem requires 50 Thousands of dollars .

therefore ,Pi Pico W The logic of pricing , Or considering the development cost .

There are two new products ？

a Pi Pico W Is that enough? ？

Raspberry pie officials obviously don't think it's in place , With Pi Pico W Pushed into the market together , There are two new products ：

Pi Pico H and Pi Pico WH.

The two new products are essentially products of the previous generation Pi Pico And new products Pi Pico W Improved type of , The biggest progress is , Additionally reserved on the basis of their respective versions Pin connector and debugging connector , The basic version has only pins similar to pads .

The purpose of the reservation device is , Easier to connect wires , It saves the trouble of welding to a great extent .

price ,Pi Pico H The price is 5 dollar （ Renminbi conversion 33.5 element ）,Pi Pico WH The price is 7 dollar （ Renminbi conversion 47 element ）, Increased than the basic version 1 dollar .

Time of sale , Raspberry officials say ,Pi Pico H and Pi Pico W Available upon release , but Pi Pico WH You need to wait longer , It is expected that by this year 8 Only in January can it be officially put into the market .

Are you going to start one ？
