Pico W with Pre-Soldered Header Compatible with Raspberry Pi Pico W Microcontroller Board, Built-in WiFi, Based on Official RP2040 Dual-core Processor, Dual-Core Arm Cortex M0+ Processor + USB Cable

If you've used a Pico before, then there are just a couple differences between the Pico and the Pico W. Obviously, the biggest difference is the W has an onboard wifi module. The other major difference is the onboard LED. On the Pico, it's addressed as PIn 25. On the W, it's a GPIO "pin". In MicroPython, it would be:import machineled = machine.Pin("LED", machine.Pin.OUT)led.off()led.on()Other than those differences, this is a solid little module. The pin headers are presoldered (except for the 3 pin DEBUG header). Unit comes with a USB cable (sadly still using microUSB instead of USB-C).IMHO, Picos are more fun than Arduinos, but YMMV.

I am building a device that can time how fast/how many times I run up stairs with a web interface. I already wrote the code, just need to find two appropriate switches. Since it has Wifi you can create a simple web server and simple API to show data. You aren't going to create Amazon with it but you can certainly load a nice page of HTML, css and js (it is built into a string, possibly can be loaded from a file) and python can read from tables that you store. This does not run a full linux distro, but it is more like an embedded device with a python or c++ interface. It does not have direct I/O for keyboards and video. For that you need its big brother, but this device certainly has uses. I read that it could also interface with bluetooth, but I haven't tried it. The chip supports it but they supposedly did not enable it when it came out, but now it works. That can be interesting for automotive with an OBD bluetooth device. Documentation is great and available on the web. It is relatively inexpensive for what it does.

I got this Pico to build a little desktop e-ink dashboard.This Pi Pico W came with pre-soldered headers, except for the 3-pin debug header which was separate.The box is the Waveshare brand box. It's marked Raspberry-Pi-Pico-W-M.You get a Micro USB cable in the box.The Pico works as expected. When I plugged it in it appeared as a mass storage device, and said it had UF2 bootloader v3.0.
