Adafruit has announced the imminent arrival of a new development board in the form of the Adafruit Feather M4 Express equipped with a ATSAMD51 Cortex M4 with floating point support and 512KB Flash and 192KB RAM.The new development board measures just 51mm x 23mm x 8mm without headers soldered in place and weighs just 5g and will be available to purchase very soon.
Adafruit explains more about the exciting parts of the Feather M4 development board, “you can use it with the Arduino IDE – and it’s bonkers fast when you do, we are shipping it with CircuitPython on board. When you plug it in, it will show up as a very small disk drive with main.py on it. Edit main.py with your favorite text editor to build your 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 Feather and your code will go with you.”
