 Okay, lady. What is this? Hey, we're putting it together some new boards. This is the IS-31FL 3741 It's a PWM LED RGB driver that can do a lot of LEDs This is cool because it's much cheaper than individual dot stars or near pixels So this is the prototype which I hand assembled and it's a little like wobbly And this is the nice ones that just came off the pick-and-place or a little toasty even so let's try out our test code plug into our Metro Mini and Moment There you go and see a nice demo showing text and color gradients We're also testing two RGB LEDs. These are only a penny a piece But there's a slight variation to one's a little brighter than the other We're getting this ready to put in the shop. It's a cute little RGB LED matrix That's all powered and controlled over I squared C stem a QT
