Texas instruments has a micro controller start kit, witch is excellent for beginners or advance users who want a cheap dev kit. This kit, at 4.30$ comes with the small board, and pin outs for easy attachment.
I've been using it to learn more about embedded coding. I've been lazy and haven't been very productive with it, but im sure a lot of people would jump at the opportunity to use something like this.
I know it be perfect for school final projects in engineering or similar fields.
If anyone got any cool projects they like to share~ hit me up!
