A funny thing happened when Raspberry Pi launched the successor to its famous RP2040-based Pico board in August of this year. One of the company's bloggers reported that the Raspberry Pi Pico 2 with the RP2350 MCU has twice the performance of its predecessor and includes many of the features it originally intended to deliver with the RP2040. On the previous launch, it either couldn't find the real estate to include essential features such as security, or the silicon didn't exist with the right power/ performance/cost metrics to offer the full spectrum of critical features.
The RP2040 is legendary despite any perceived shortcomings. Still, Moore's Law has seemingly caught the wave of the tiny, embedded boards, and the RP2350 has plenty of processing horsepower, memory, and I/O resources packed into a 21mm-x-51mm board. Although many projects featuring the RP2040 have been documented on Circuit Cellar's pages, including this edition, one can only imagine what projects the RP Pico 2 might inspire with a more complete allotment of computing resources.

New TI MCUs Enable Edge AI and Industry-Leading Real-Time Control to Advance Efficiency, Safety, and Sustainability
Texas Instruments (TI) introduced two new series of real-time microcontrollers that deliver advancements to help engineers achieve more intelligent and secure processing in automotive and industrial applications.
Using Amazon Alexa to Control Custom IoT Gadgets
In part two of his article, Brian describes integrating custom IoT gadgets with Amazon Echo using emulation to receive spoken alarms. In part one, he used emulation and Arduino Cloud services as a middleman.
Holiday Hangover Hardware Hacking
Having too much cheer during the holidays? In this month's article, Colin offers a diversion from the jolly season by urging developers to retreat to the basement to brush up on hardware hacking skills. He shows how a low-cost Raspberry Pi Pico and a TP-Link Tapo C200 smart IP camera could become the next automated bird deterrent or a home automation server.
Datasheet: Microamps Per Megahertz Ultra-Low Power MCUs Minimize Current Consumption
How do chip makers differentiate if many ultra-low power MCUs on the market feature the same processor core? The peripherals and different power states offer various ways to manage current consumption down to microamps per megahertz.
Smart Home Lock Down Matter Provides Security Blanket
As more devices in the smart home connect to the Internet, they become increasingly vulnerable to outside attacks. Developers can now add the latest security measures to their Smart Home devices through Matter.
Basic Pulse Circuits
In part one of a three-part series, Wolfgang wrote how basic pulse circuits help digital circuits, such as embedded boards with ARM processors, deal with pulse trains or bursts of pulses from the outside. In Part 2, he dives into enabling flip-flops, timing parameters, and synchronization, design tasks needed to capture, detect, and filter pulses.
Building a Wi-Fi Router Watchdog
Dev created a watchdog for a Wi-Fi extender using a Raspberry Pi Pico. This monitors Wi-Fi connectivity for his smart home lighting system, which would require a reset twice a year due to rapid power interruptions.
