I think this Announcements forum should be the right place for this message, but if it’s not I hope the moderator can relocate it to the right forum.
Parallax customers (teachers) from schools that switched to Arduino have been asking Parallax Education staff for a while about generating some Parallax hardware and documentation that would be compatible with Arduino.
Our answer was the Board of Education Shield for Arduino (or BOE Shield for short). The new BOE Shield was just listed for pre-order and we’re beginning to post material that not only explains how to use the Parallax BOE Shield, but also Arduino in general.
We will print the “Robotics with the BOE Shield for Arduino” book soon but first will be posting the whole book online (for free access) as it comes available chapter by chapter at learn.parallax.com:
You can currently access the first chapter of the book which shows an introduction on Arduino and students can follow this chapter with just an Arduino hooked to their PC (they don’t even need any Parallax hardware in Chapter 1).
Adafruit is already setup as Parallax distributor and if Adafruit customers are interested in buying these products I’m sure Adafruit could carry them.
I hope you find this information useful and a good fit and use of your Announcements forum.
