Off-Grid Message Board

Since this message board uses a LoRa mesh network, it does not need to rely on Wi-Fi, cellular, or any centralized infrastructure to receive and display messages. - Adafruit Learning System

Marquee - a new way to create interfaces for e-paper displays

I spent a couple of months working out how to avoid manually programming interfaces on an e-paper display that would take up valuable memory and processing power. The result is Adafruit Marquee, a way to visually create interfaces for e-paper displays and send them directly to the device without any additional coding. Assets like fonts, images, and layouts are not stored on the device itself. - Adafruit Playground

UDP Broadcasting and the Brave New World of IPv6

Maya Posh explores UDP broadcasting in IPv6, and compares it to the traditional IPv4 approach. - HackADay

Nordic nRF54LC10A

This chip came out the week I’m writing the IoT Monthly - so why not include it? Nordic’s nRF54LC10A is their new entry-level wireless SoC for ultra-low power wireless applications over BLE, Thread, Zigbee and Matter. -Nordic Semiconductor

Support Adafruit

Here at Adafruit, we sell all of these amazing components, but we couldn’t find a good way to interact with them over the Internet. So, we decided to create our own IoT platform, and that’s Adafruit IO. It’s built from the ground up to be easy to use and platform agnostic (connect any development board or device!). For those who want to get a project off the ground without programming - Adafruit IO offers a No-Code interface for building IoT electronics projects using WipperSnapper, our open-source IoT firmware. Support Adafruit’s open-source development by subscribing to Adafruit IO Plus, the upgraded, all-systems-go version of the Adafruit IO service.
