NEW IoT Hardware: Adafruit Matrix Portal - CircuitPython Powered Internet Display


Folks love Adafruit’s wide selection of RGB matrices and accessories for making custom colorful LED displays… and Adafruit RGB Matrix Shields and FeatherWings can be quickly soldered together to make the wiring much easier.

But what if we made it even easier than that? Like, no solder, no wiring, just instant plug-and-play? Dream no more - with the Adafruit Matrix Portal add-on for RGB Matrices, there has never been an easier way to create powerful internet-connected LED displays.

To celebrate its release - we’ll be highlighting some of our favorite Matrix Portal guides in this newsletter.

Amazon Details Sidewalk, a new range- extension for Echo and Tile devices


There was not much information available last time this newsletter covered Amazon Sidewalk. Last week at Amazon’s hardware event, they provided some details about the new service. Sidewalk “uses Bluetooth Low Energy (BLE), the 900 MHz spectrum and other frequencies to simplify new device setup, extend the low-bandwidth working range of devices and help devices stay online and up-to-date, even if they are outside the range of home WiFi.” New Echo devices are capable of acting as a Sidewalk Bridge to extend the working range of connected IoT devices - Amazon Developer Blog
