 AW 9523, 16 pin GPIO expander on I squared C, and LED drivers that use constant current. 16 pins arrayed around the top and the bottom, there's I think 11 on the top and 5 on the bottom there, and all those pins are in pairs because they each have that V in for the voltage. 16 little 3mm red LEDs plugged into the board, and as you can see I'm doing some different little fades and lighting them in some sequences, turning them on and off, right now they're getting brighter, brighter, brighter, and then they'll drop down. Use the little STEMA QT connectors, you can plug in up to four of these on one microcontroller, and then you'd be able to run buttons, LEDs, galore. That's the product pick of the week this week.
