Raspberry Pi Pico W Launches For $6

The Raspberry Pi Pico W is an update to last year's Raspberry Pi Pico using their in-house RP2040 silicon. The Pico W is a small update to this IoT platform that has already sold more than two million boards.

With the Raspberry Pi Pico W, there is now 802.11n wireless networking added to the Pico platform to make it more attractive for IoT use-cases. The Pico W retains pin compatibility with the original Pico. The Pico W makes use of an Infineon CYW43439 wireless chip.

Aside from the addition of 802.11n wireless networking, the Pico W is the same platform as the Pico. Rather than $4, this 802.11n WiFi variant will sell for $6 USD.

Also launching are two versions with pre-soldered headers:

Pico H ($5) and Pico WH ($7) add pre-populated headers, and our new 3-pin debug connector, to Pico and Pico W respectively. Pico H and Pico W are available today; Pico WH will follow in August.

[...] Eagle-eyed readers of datasheets will notice that CYW43439 supports both Bluetooth Classic and Bluetooth Low-Energy: we have not enabled Bluetooth on Pico W at launch, but may do so in the future.

    I may just pivot my Particle-Argon development to a Raspberry Pico W instead... hopefully it is competitive on the power draw front, I'm trying to maintain a (very low usage) wifi connected webserver on 50 watt-hours per day or less.

    Technical question for those who know: Is it really required for all BLE devices to have agonizingly long connect times? I understand that they only "listen" at intervals to conserve energy, but it seems like the user experience of every BLE widget I have encountered starts with an excruciatingly long (sometimes 90 seconds or more) delay followed by an uncertain / unreliable and remarkably slow connection, and usually some buggy software to go along with it. My latest disappointment is this thing: https://www.homedepot.com/p/Melnor-4-Zone-Bluetooth-Water-Timer-93280/315869270 [homedepot.com] which seems to lack effective checksums on its communication. You can spend 5 minutes programming each channel, and once in a random while the program for one of the channels will overwrite itself on another channel - even a channel you haven't touched. Then the plants that depend on that water start to wilt a few days later...
