GeeekPi 3PCS Raspberry Pi Pico W with Pin Headers - Raspberry Pi RP2040 Chip, Wi-Fi Wireless Connectivity

Works as expected. Hardware is much more reliable than some others like cheaper ESP32 boards or knockoff arduinos.Waiting keenly on BLE updates in micropython.

The GeeekPi Raspberry Pi Pico W kit is just like other picos on the market. I like thie pico because it is easy to get started and is much more capable then the Arduino. I do embedded sw for my day job so having a micro that you can control almost anything on is great! This is an inexpensive board that can be used for almost any embedded project. I plan on using it to sample an ADC at about 1us and then transmit this over wifi. To have a controller that can sample this and get it off fast enough is pretty crazy. I really like this micro and will be buying more.

Three pieces nicely packaged. Did code for on board LED test and it did not lit. I realized, onboard led has different callout then regular pin in code. Tried on all three - they worked. So, beware of this. More expensive then MicroCenter.

I am using these for testing home projects. Thanks

I own an original Raspberry Pi, as well as a Raspberry Pi 3. I always thought those were great for tinkering but I also considered them overkill for tasks an MSP430 or Arduino could accomplish. I'm surprised the Pico W has been released so many years after those platforms, but offers the flexibility of an Arm M architecture CPU. Actually, two of them!The size compared to the "full size" Raspberry Pi's is pretty stunning. It's a little wider and a little shorter than the footprint of a AA battery laying down. My Linux box is offline, so I quickly used windows to load the LED blinking and Hello World examples from the excellent documentation. Other than a quick hiccup with a bad USB cable, the examples were exceedingly simple to program and execute.To program the Pico W, all you do is hold down the BOOTSEL button, and plug in the USB cable. The Pico W mounts itself as a mass storage drive. From there, you just drop the uf2 file onto the Pico W mass storage drive. This somehow programs the Pico W, and restarts it and allows it to run the program. I have never had such a simple setup procedure for flashing a device. The MSP430 is very streamlined as well, but even that requires some programming hardware which happens to be included on a lot of the MSP430 evaluation boards.I haven't used the wireless portion yet. The one item I'm contemplating is whether I want to start tinkering in C/C++ or micropython. There are pluses and minuses to each one. I'm guessing I'll choose the one which fits the project I have in mind. I am curious to mess with the wireless stack in C/C++. It has been a long time since I have tackled that!Ok, so one last thing should be said. These boards are supposed to be $4 each. The current price for a three pack of these boards ($40) is well out of line of the expected price. Raspberry Pi boards are in high demand currently due to the silicon shortage and high demand. Hopefully when the dust settles, we'll be lucky to be able to buy these for the $4 they're supposed to be.
