This all of course sounds a lot more significant until you remember we're making a small hop from $4 to $6.
The $2 extra is well worth it as it adds Wi-Fi support to to the teeny tiny device, which has been called the Pico W. This might not be a big deal for many projects, but according to the , the addition of Wi-Fi seems to be just what the Pico needed. Especially when using the board with sensors as the data can be easily transferred over a network without much extra effort on the part of the user.
Other than that, there aren't any notable changes to the Pico board, which means it's very similar to this
I could employ one in my open source energy recovery ventilator if it has libraries for iot functionality, so the machine can be set to turn up/down the ventilation on a schedule, saving even more energy/making the air more fresh when you arrive home etc.
Remote controlled 3d printer is looking easier by the day
The Pi has built in WiFi tho right?
Hopefully Raspberry Pi's level out soon, its so hard to find one that's not triple the price.
Perfectly timed with the release of the software that turns the Pico into a modchip for the Gamecube.
