analog in). It's the same chip as the Feather nRF52840 (https://adafru.it/DLQ) but

really really small

. So it's great for

those really compact builds. It even comes with 2MB of QSPI Flash built in, for data logging, file storage, or

CircuitPython code.

The most exciting part of the ItsyBitsy is that while we ship it with an Arduino IDE compatible demo, you can also install

CircuitPython on board with only a few clicks. When you plug it in, it will show up as a very small disk drive with

code.py on it. Edit code.py with your favorite text editor to build your wireless-enabled project using Python, the most

popular programming language. No installs, IDE or compiler needed, so you can use it on any computer, even

ChromeBooks or computers you can't install software on. When you're done, unplug the Itsy' and your code will go

with you.
