Running lwIP itself in the Fuzix kernel may be an option but right now Fuzix has to run from RAM as the flash XIP stuff gets on very badly with filesystem writes to the flash, and lwIP looks like it’d use 70-odd-kB of space, which isn’t trivial. I wonder how hard it would be to add networking support for the Pico-W?įuzix actually runs its own networking stack in userspace based on uIP, so I’d need a frame interface with the W’s networking chip (which is actually an ARM M3-based device with lots of RAM and ROM, which is considerably more powerful than the RP2040 itself!). I’m actually just now fixing the bitrot on the Fuzix port to the Pico. Posted in Hackaday Columns, Microcontrollers, News, Slider Tagged ESP32, pico, raspberry pi, rp2040, wireless Post navigation
And in these days of silicon shortages, it’s nice to have a couple of options. Either way, it’s firmly in the ESP32 module price range, so you’ve got some comparison shopping to do if your project needs a microcontroller and WiFi. How you see things probably depends on your order quantity. You can view this two ways: a small $2 premium over the old Pico, or a price increase of 50%. The price? $6 for the whole shooting match.

The CYW43439 is also Bluetooth capable, but there’s no firmware support for that yet, but we wouldn’t be surprised if it showed up soon. It looks trivially easy to get it working, and it’s based on the time-tested lwIP stack, a classic in the embedded world. They had some extra real estate on the PCB, so they’ve added an Infineon CYW43439 WiFi chip, and voila: Pico W.Īs of now, the WiFi is supported in both the C SDK and the pre-baked MicroPython image. This in turn has two Cortex M0+ cores and a good chunk of onboard RAM, which has made it a popular target for MicroPython. The Pico is, of course, the Raspberry Pi microcontroller dev board based on their RP2040 microcontroller. Boo! So until it shows up, here’s what we can glean from the press releases and documentation. We were going to get our hands on a sample unit and kick its tires, but it’s stuck in customs. News just in from the folks at Raspberry Pi: the newest version of their Pico has WiFi and is called, obviously, the Pico W.
