What's smaller than a Feather but larger than a Trinket? It's an Adafruit ItsyBitsy nRF52840 Express featuring the Nordic nRF52840 Bluetooth LE processor! Teensy & powerful, with an fast nRF52840 Cortex M4 processor running at 64 MHz and 1 MB of FLASH - this microcontroller board is perfect when you want something very compact, with a heap-load of memory and Bluetooth LE support This Itsy is your best option for tiny wireless connectivity - it can act as both a BLE central and peripheral, with support in both Arduino and CircuitPython
ItsyBitsy nRF52840 Express is only 1.4" long by 0.7" wide, but has 6 power pins, 21 digital GPIO pins (6 of which can be analog in). It's the same chip as the Feather nRF52840 but really really small. So it's great for thse 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.
Here are some of the updates you can look forward to when using ItsyBitsy nRF52:
Each order comes with one assembled and tested ItsyBitsy nRF52840, with headers that can be soldered in for use with a breadboard.
So what are you waiting for? Pick up a ItsyBitsy nRF today and be amazed at how easy and fast it is to get started with the teensiest Bluetooth dev board we have.
