Great choice for small electronic devices
RP2040 has recently become my favorite microboard for building relatively simple and compact electronic devices (which usually contain a couple of inputs, a couple of outputs, a couple of buttons, a potentiometer or two and an I2C OLED display). For simple status signaling, it has a very bright built-in RGB LED which doesn't use any of the onboard pins, of which there is a limited number. I have already made a laser control box, a temperature control board for a custom-built 3D printer and a spot welder based on this board, and all of them work well. Sure, this board is not as powerful as Teensy 4.0, but it is not as expensive either, and noticeably more compact. Kudos for including the USB-C port, which is much more convenient than Teensy's micro USB. RP2040 can be soldered to one side of a PCB, leaving the other side completely free to run traces for other components, without pin holes getting in the way. For the types of devices I mentioned before, it has more than enough processing power. If such power is not needed, the clock speed of the CPU along with power consumption can be dialed down at compile stage, which helps RP2040 to run much longer when powered by battery. The PWM library is not what you would call an Arduino standard, but once you're familiar with it it's just as fast and capable. Overall, nice and very usable microboard.

This is the future
Tons of processing power in a package the size of your thumb. So tiny that any USB cable plugged into it has to be secured as it weighs more than the MCU itself. Barely uses any power even while operating at full tilt, and absolutely just barely sips on a battery while in standby mode.You’d think that the GPIO would leave something to be desired, but given its size I wouldn’t say that’s much of an issue. If you need more pins, get an expansion board or use a different model.Super useful if you’re trying to shrink down your projects - pairs well with displays and other components from Adafruit, Waveshare, etc.

Great device so far!
The media could not be loaded. Updated review. Found more information and I'm quite pleased with the Xiao Rp2040. So far it works with SSD1306 Oled display. See attached video of 3D plotter I wrote. Using the U8g2 library configured for SSD1306. I also tried an SH1106 display. the 1306 driver in the u8g2 library works with minor glitches, the 1106 config doesn't work at all. I'm trying to find libraries for use with ST7735 and 7789 displays.I also wrote a sketch that generates random color on the internal RGB LED, when fades from one color to the next. Doesn't require any external connections. That LED is bright!It's a work in progress of course.

No instructions.
Haven't used yet, because I'm a beginning learner with such.No instructions, not even a link. Somewhat understandable though, it being tiny.

I love this board!
I just got the Seeed RP2040 board, and it's a great improvement over the previous generation (the Seeed XIAO).The older Seeed XIAO was fun and easy to use, but this new RP2040 is even easier to reboot, to move into CircuitPython mode, and to code for!I can power 7 LEDs and a small motor all at the same time!I'm going to buy more soon :)

Cool little device!
Purchased this to create a circuitpython gift for a friend. This is the first microcontroller I’ve purchased and it was pretty easy to figure out how to flash it with circuitpython. Both Visual Code and Mu make it easy to connect to and update the code on it. I don’t know circuitpython but I’m learning as I go and enjoying it.

Fun to play with
Low power consumption, small footprint. I'm using it as a plant watering smart controller for a starter. I plan to reconfigure and add a radio so I can add to my RF network of controllers.

Just works
I like rp2040 in all the different formats. This is probably my favorite due to the small size
