Really intrigued about the particle boron with no monthly fee.

    I bought mine years ago for around $40. I think they still sell it but it costs a bit more now. They have cheaper boards, but I don't know if those have the no monthly fee thing. It's a very cool little dev board, but be warned! Unless they changed it, there's no reverse polarity protection on the battery connector! It uses a regular jst battery connector which can physically only plug in one way. I foolishly assumed this meant that it couldn't be plugged in with reverse polarity, but it turns out there's no established "correct" polarity for that connector and the battery I had fried the first board I bought. If you buy one, make sure you double check the battery polarity!
