ArduinoNano RP2040 Connect with Headers

Incredible system, you can use the DMA to write bitmaps to a screen from the onboard flash chip. That’s 16MB, plenty for me to pre render all the graphics it’ll ever need during compilation. You can show some cool dense stuff lightning fast on a 240x240 screen and barely use 20% of its ram and very little cpu time.Two cores at 130MHz on an arduino nano?? 260kB ram and 16MB flash? And a DMA? That’s amazing! Makes you think back to the 328p days… Bluetooth, WiFi, accelerometer and mic…I’ve found their quality exemplary and ease of use par for the course for a microcontroller.

I'm very impressed with the capabilities of this chip in the classic Nano form factor. My plan is to fly it, so size and weight are important, and I couldn't get my sketch to fit in a classic Nano. One recommendation: go to Github and check out Earle Philhower's code for this board.

I'm not sure what I'm going to make with it but the quality is superb

This is a really good chip from a programming point of view. My complaint however, is the USB connection is really flimsy and came off when I tried to pull the USB connector out. So I'm out sadly out 30$.

Great job with the board! The combo of the pico with the power of the arduino chipset makes this a powerful little guy!

The size, the speed.

I've purchased three of these so far in two separate batches: Two in one, one in the other. I encountered the same issue which I now see others have also reported here: The third of my units was dead on arrival.- The dead unit's power indicator lights up, but it never boots into the default "Blink.ino" script that comes pre-installed on these units.- The microUSB interface was non-responsive and was not recognized by either my PC or the ArduinoIDE.- Neither double-tapping the on-board reset button nor connecting a jumper between the RESET and GROUND pins would open the mass storage.I encountered none of these issues with my other two units, though with one, I did encounter a problem reported here by another user where the microUSB port breaks off easily.I love Arduino, and the RP2040 is an amazingly versatile board, but there appears to be a lot of inconsistency in terms of product QA when ordering these through Amazon. My advice for anyone considering purchasing this through here out of convenience is to test your board for any issues before the return window closes.

I received one and i couldn't get the USB port to work unless i was pressing down on it, got a second one and as i was finalizing on a breadboard, i went to put the USB cable in and the USB port completely fell off . I've never had this issue with any other board, but this RP2040 just seems to hate me. Now I'm left with a nano connect and no USB Port...
