Lilygo T-Deck Pro is a mobile dev kit with ePaper display, QWERTY keyboard, 4G (liliputing.com)
Last summer LILYGO launched a pocket-sized mobile communications device called the T-Deck Plus that looks like a phone, but is really more of a mobile dev kit with a 2.8 inch IPS LCD display, a BlackBerry keyboard, and support for WiFi, Bluetooth, and LoRa wireless connectivity… but no support for cellular networks.

Ask HN: Best way to learn STM32 and embedded for beginner (ycombinator.com)
My google foo is producing garbage - Most tutorials don't go past blinky. Most suggest CubeIDE, others have suggested ChibiOS. I followed some tutorials on stmbase to get a blinky going on a ST Nucleo, but it used a HAL library and it feels like cheating.

Just barely fitting a full Wi-Fi stack on the nRF9151 (danielmangum.com)
In my last post on the Nordic Semiconductor Thingy:91 X IoT prototyping platform, I outlined the features and architecture of the device. The combination of wireless protocols on the Thingy:91 X (Bluetooth LE, LTE-M, Wi-Fi) make it a compelling foundation for a wide variety of applications. However, there are a few intricacies to the protocol support.

Demystifying Common Microcontroller Debug Protocols [video] (media.ccc.de)
Many developers know that the answer to "How do I debug this microcontroller" is either "JTAG" or "SWD". But what does that mean, exactly? How do you get from "Wiggling wires" to "Programming a chip" and "Halting on breakpoints"? This talk will cover how common debug protocols work starting from signals on physical wires, cover common mechanisms for managing embedded processors, and ending up at talking to various common microcontrollers.
