“Not easy to get hold of an M4 right now. I wanted to graduate from the terrific Arduino Due with Arm M3 to the even more terrific M4 with a single-precision floating-point unit. Mirabilis, Pimoroni have several. Good price and delivery too. Delivered way quicker than the estimate. This is a quality SBC, well-made and loads of options. As soon as I figured out how to unlock the flash I had it under control for bare-metal development using the pre-socketed SWD mini-connector and a well-known JTAG interface to a well-known cross-compiler and debugger. A snip longer to get the latest version of FreeRTOS running in a simple round-robin. Arduino, Pimoroni, Adafruit, S*****, R***** C*********, Wittenstein, all class acts.”
“As a n00b on control boards I decided on this model as it came along CircuitPython.
I had tinkered with some Arduino boards before but always found the compiling and flashing method cumbersome and programming in C was never my taste. Python is great for developing and you can get fantastic results very quickly. Getting your scripts to run just by uploading them and having a basic IDE that allows you to check your code as well as some auto-completion is a breath of fresh air. You can come up with ideas in a whiffy and implement them painlessly.”
