The Grove – LED Matrix Driver v1.0 can be a nice helper when you need to driver a dual color LED matrix. It is built around the neat little chip STM32F103C8T6, which works at a frequency of 72MHz and very low power consumption. You can use the drivers to control a LED matrix sized at 64x32 or 32x16. And as though we’ve prepared handy and easy-to-use libraries, you only need to write few lines of code to get it working quickly and display whatever you wish.

Wiring is quite simple as well. Connecting the driver to your development board to the onboard UART interface with a Grove 4-pin cable and to your LED panel through the 16 Pin DBSTAR_HUB08A Header connector, and then you are ready to roll.

You need a WiFi Internet connection, and a smartphone or tablet for the Echo App. That's it. It is easy to set up, but it may take you a while to figure out all of the little things that the Echo App can do.

BEWARE this is NOT STEREO and it is NOT MONO. This is only one channel. You will not hear part's of songs (recorded in stereo) that are only played through the left channel. Kinda ridiculous. Still it is a decent sounding speaker.

★★★★★ Great bag
Purchased this for my 23 year old daughter in the butterscotch color. Great versatile color. She loves the size -- perfect for day or going out at night. Chain can be double to shorten for nighttime and left long to wear as a crossbody during the day.
