Adafruit(PID 3505 Metro M0 Express - Designed for CircuitPython - ATSAMD21G18

Produit commandé pour mon travail , le premier exemplaire était hors service dés la réception , pas reconnu par l’ordinateur ( alors que j’utilise un câble avec données ) bouton reset inopérant ( simple ou double clic) et pas de lancement du programme interne , je l’ai donc renvoyé . Le second exemplaire fonctionne lui parfaitement , il a été reconnu tout de suite et le fichier systeme crurent.uf2 était à jour . Délais de livraison très correct deux ou trois jours , retour du produit défectueux sans problème .

I purchased this after I got the Circuit Playground Express. I have been programming Arduinos for years and if you are doing some basic tests, this is great. I have only been programming in CircuitPython at this point but the great thing is the number of test cycles you can get is much greater than what you get with Arduino due to the lack of a compile cycle. If speed is a concern, do not use CircuitPython as I do notice a significant speed limit. I am using a 60 NeoPixel ring and with some of the effects I have programmed, there is no need to pause / sleep / delay due to the interpreter. I am still working with this board and I haven't tried out all of the features. The next task is testing the analog out to see what it can do. It would be interesting if this can produce true wave forms.

Used these with Elegoo robot car kits so kids could program with CircuitPython instead of C++

This thing is pretty neat! You literally just need to drag and drop your python script (+libraries) to the flash and everything just works. Performance wise, I would check out other reviews.I will definitely move toward this board for a lot of the projects in the future. For now, the public knowledge base and resources for this fella are still developing on the Python side.

First it worked then it didn't. A waste of my money I am afraid.
