You can use the same Arduino IDE now.<p>Which makes more sense depends on your needs; if you&#x27;re heavily invested in the Arduino ecosystem (primarily add-on boards) it might not be a great fit.<p>But for a GP board with enough GPIO to get small things done, it&#x27;s a great board, and just as easy to use. For example, I have a number of lights hooked up to it using SSRs. I use it more as a peripheral chip rather than a main controller, because it&#x27;s so ridiculously cheap and easy to use.<p>Where I used to use IR comms to hook together small devices (light&#x2F;power controllers, sensors) I use these now.
